Hkey_ Root Philip Bedford not necessarily a bad thing, my main pc doesn’t support booting for Nvme although I’d rather keep the OS on its own SSD, I install all my apps and games to the nvme drive. There is no real speed increase to load times with nvme, only really visible when copying large files or running benchmarks.

After 3 days of tinkering and 3 weeks after I purchase this. This is definitely NOT an ARM SBC for the beginner or the average RPi4 user. It has become one of my favorite ARM SBC boards. I managed to solved 99% of the issues it initially had. It requires so much tinkering it kind of reminds me of the old days of linux 20 yeas ago. RockPi4c is a very flexible board with great documentation and support via official forum that require manual configuration for almost each component. I loved it. Best way to keep this board cool at all times, even under full load running less than 46 degrees is to use a 20mmx20mm 1.0mm copper shim between the radxa large heatsink and the CPU. Apply some quality thermal paste on Top and bottom of the Copper shim and you're golden. Do this and you will achieve From 20 to 30 degrees Celsius LESS now. With the Copper shim, There is no longer need to use an active fan with it. Currently, official Debian 9 is the best OS for this relatively new board, it has less than 3 month old. Keep in mind, RockPi4B images and documentation won't work on newer RockPi4C because of hardware differences with dual video output. Some other features like MIPI display serial interface won't work without modifications and currently there is No working version for 4C. You need to change and compile 4B overlay with dtc to create the dtbo file by disabling min DP port because RK3399 only supports two(2) video output engine. Built-in Bluetooth requires a manual patching in order to work on 4C. This powerful and customizable board does NOT work out of the box. Overall, I'm truly impressed with Radxa boards. I will be buying a RockPi N10 when becomes available and definitely the next RK3588 board from Radxa when get released in 2021 or 2022.

[@IndependentNewsMedia]

Enjoying the SBC industry trying to out do each other, bringing wider choice to tinkerers 👍

[@zen608]

Indeed. Competition encourages these companies to really push their limits and in the end the consumer wins.

[@patdbean]

But all these non-pi SBC all come down to the same thing, good hardware but limited software and long before the software ecosystem catches up the rasburry pi's hardware will have moved on anyway.

[@WithinandThroughout]

Literally, got to love competition in a free market.

[@TheOleHermit]

@@patdbean Exactly! RADXA simply copies RPi, just with more impressive HW specs. But, that's only half of a computer system. IOW, RADXA simply throws some impressive HW onto a board, then mostly depend upon their community to sort out the software issues. That may interest some bored Linux gurus, but it took them 3 generations of the ROCK Pi, just to get the HD video playback to an acceptable state. The heatsink still covers the eMMC module. The M.2 connector still points in the wrong direction and the ribbon cable still obstructs the microSD slot. The fragile M.2 'shim' adapter, flimsy ribbon, and expansion board are only remaining after thoughts from the 4B. Still no onboard DC power connector, which dedicates the USB-C to only power delivery. Still no on-board PWM fan connection. Still no case to house the static sensitive components. So, if you actually want to MAKE SOMETHING USEFUL, start with designing your own DIY case if you want to waste the extra time and money. But, admittedly, the ROCK Pi ships inside a nice plastic throwaway case. 🥴 Sorry for the rant, but I've already had the RADXA experience and I'm triggered every time I see one reviewed. Once burned, twice shy. Best regards. Stay safe, everyone!😎

[@laurinneff4304]

[@johnjoyce]

It’d be great to see more about setting up the Real Time Clock with that battery connector along with booting to NVmE and/or MMC. After that, it would be fabulous to see an example of USING the USB OTG feature. I think those features are a little more challenging but offer much more rewarding overall usage for turning this SBC into a project. For the OTG feature, an interesting starting point might be as a fake keyboard or as a keyboard translator, translating a keyboard’s key codes to another set of keycodes. (Such as taking a a PC keyboard and making it work for a Mac but the Pi being a smart configurable intermediary)

[@runepedersenDK]

Interesting with the comparison between different SBC's. But I always ending choosing the Raspberry Pi series, mainly because of: 1) I want to support the pioneer developers at Raspberry Pi Foundation 2) The community 3) The stability, and (mostly) bugfree OS

[@pilabs3206]

Pioneers? Rpi is not the first sbc around at all (by far)

[@greyline3051]

You sold me on the 4C. It is a very fast SBC, but I chose to use the heavy heat sink in order to avoid having to use a fan. This choice of setup is unsuitable for what I had hoped would be a "tablet like" application. I'm going to try the Radxa Zero instead.

[@DallasMike424]

Ah, a very good spot! This said, I have used this board to watch a lot of KZbin now, and performance has been very good.

[@lander1591]

The main reason I stuck with a Pi4 4gig is the large user base which will ensure device and software support. I have heard horror stories about unique SBC's being paperweights as none of the distro's supported the hardware and firmware requirements, and community interest and uptake was too low for anything to be tailored for them.

[@BlueBird-wb6kb]

Pick the superior product and the community will come as well, so your way of thinking allows inferior products to succeed.

[@abchk22]

@@BlueBird-wb6kb Only one is willing to tinker and be patient I feel. ARM SBCs are a very different experience than x86 PCs currently.

[@TheOleHermit]

You must have read some of my comments. 😎

[@TheOleHermit]

@@BlueBird-wb6kb How do you figure? IMHO, purchasing half baked products allows inferior products onto the market. Burned customers (self included) waste their money. I'm looking at my ROCK Pi 4B paperweight, only collecting dust on the shelf, after wasting ~$200 and several months on troubleshooting. Underdeveloped products only cause needless suffering. They should not be marketed until they can live up to their promises. HW is only 1/2 of a computer. Without a stable, fully functional distro specs are useless. Maybe I'll glue some impressive components onto a board, then sell it to naive customers. I'll even start a support forum, so that folks like you can figure out how to make it work. Works for Radxa.😒

[@KameraShy]

And how many such SBC boards will the market support? Are the additional features of this 4C compelling? If so, will they appear RSN on the Raspberry Pi?

Another great video. You are a must see every time. Dual video was a hurdle that had me purchasing a RPi a few months ago. 8 megs of ram would be a slight stumbling block for me. A complete fail with the NVMe slot sticking out into nowhere. Such a great idea with poor execution.

Another expert video on a SBC! A pretty impressive one as well for the money. My suggestion to improve it: It comes packaged in a pretty good acrylic case - Surely it would not have been too difficult to design and construct this case as a housing in itself? Cutouts for the ports, heat sinks etc. A huge advantage over competitors, I would think?! Just an idea, where I think the packaging could form a part of the end product.

[@MarkTheMorose]

Nice idea; it would also be a good way to prevent plastic waste. If they could make the case stable when sitting on its side, that would improve the cooling.

"Hardware is useless without software". I often see videos titled "raspberry pi alternatives" or raspberry pi killer" like videos in my feed. What is common in every one of them is 1) lack of software support and 2) less community involvement. The first can be fixed with some updates here and there but the second one will, in my opinion, never equal raspberry pi. Raspberry pi has been here for 11 years now and in that time it has created a firm foothold in the SBC market, deserved too. It is in everything from 3d printers to space stations. It was wide software support and a huge community backing, tinkering and supporting it. It has many add ons for it, HATs, cameras and what not. That said, if raspberry pi foundation sits on their back and do not make new innovations to the SBC people will start to migrate to other SBCs. Right now, I do not see much reason to choose other SBCs over the pi.

[@boink800]

At least there is one distro which can run on the Rock Pi 4C. I am still amazed why they often release these boards without a working OS.

Great Video - Thanks so much for this Prof. Chris! Just a couple comments on this board. Overall I really really like it, and in time, I will buy one for a certain spot where I need a light-duty Linux desktop here for home. But - The two main issues you correctly point out need to be fixed first. They have to get the large heatsink issue worked out and provide a large aluminum block heatsink for the Rock Pi 4C.. Also, not being able to boot properly from SSD is just a blunder. It seems that their marketing guys or the bean-counters forced the technical guys to rush this to market before these issues were worked out.. BAD! As a workaround for the SSD booting issue, you can always boot from SD-Card or eMMC (or whatever) and just put the bootloader and grub on the initial boot medium and then point grub to the SSD to boot the operating system.. You can do that with *any* Linux/Unix/BSD variant, you just need to boot SOMEthing and then grub takes it from there and points to your desired mass storage.. But you have to know how to set that up.. Some Assembly Required... Thanks Again for the great video on this new and very capable SBC!!

As a sidenote, at about 4:35 you noted the board had 802.11 a/c WiFi. The slash implied that it supports a and c, and while 802.11a existed (it was the old old original standard), 802.11c did not.

I wish one of the SBC manufacturers would release a board with the latest ARM processors like an A76 or the new A77, of course, the price would be increased somewhat but I believe there is a need for faster SBC's with more memory, just look at the success of the RPi4 8Gb and the multitude of OS's that have taken advantage of this boards abilities.

Hello Christopher! I really learn a lot from your videos and this time I thought I might contribute something on this subject. I have my Rock Pi 4C booting and running on the Acer 128 GB NVME SSD that I purchased from Allnet. This is an approved NVME SSD to boot and run for Rock Pi 4B and 4C. I was able to achieve this after running a command to verify the SPI Flash module: ls /dev/mtd* This showed the following: /dev/mtd0 /dev/mtd0ro /dev/mtdblock0 I then ran the command: sudo apt update && sudo apt upgrade During this process I noticed the system started writing the block info to install the bootloader into the SPI Flash. I remembered this happening when I was trying to boot and run Ubuntu Bionic from my approved HP EX 900 NVME drive for my Rock Pi 4B. So I then installed Debian For Rock Pi 4C on the previously mentioned ACER NVME and pulled out the SD card I was booting from and installed the NVME only. No SD card no EMMC module. NVME only. I rebooted and to my surprise the NVME booted up Debian. So I suggest when trying to boot NVME check that your NVME has been approved by Radxa. All I know is that I have my Rock Pi 4C booting and running from NVME, as well as my Rock pi 4B doing the same. Anyway, I hope this helps.

You know, although I do love the Pi and associated ARM boards, I have to say that for the moment x86 is still my go to choice system for most stuff, and what I was doing with the Pi's (MediaCenter and Router) I'm doing much better performance and features wise with the Atomic PI, which is based on the same Atom CPU as the Rock PI X. For my Router solution (custom) I got OpenWRT on one AtomicPI, for my MediaCenter I actually went with eLive Linux (64 bit) and I am astonished at the performance I got out of the AtomicPi! (Not available for ARM unfortunately), this thing is booting fast as heck and performance all around if praise worthy! I'd recommend you test your RockPI X with eLive (maybe give 1£ or 2£ to the project, I did give 2€ but ended up using the Beta version regardless, and still worth every cent!

[@josephtremblant2173]

It depends on the m.2 drive. Samsung EVO 970 plus NVMe does 940MB/s on RockPi4C for reading and writing speeds. That's is almost 3x times as fast as USB3 SSD speeds on the Raspberry pi 4.

GreenRecon I think you might be right! Memory, it seems, is a reconstruction at best! I don’t think I have the first book anymore to look it up ....

Yes, a leopard was on the sign!

Fantastic video Chris. What a beast of a SBC this is! Regarding your knife cutting skills, maybe I should create a new channel for you "Explaining Stanley".

Hi Christopher. It is a nice board indeed. Now I got the Odroid N2+. Very fast CPU, but not as well supported yet in Linux, bad I/O and bad working USB3. So the RK3399's are still my favorite. I wonder how well it works with multi dislpay. I guess good GPU drivers will be needed to make it a good experience. Good the RK3399 has Panfrost. I've got a video showing how to install it on RK3399. Finished my N2+ Linux review this week. It's good to be able to review something new again. I can't wait for the RockPiX. x86 and a bit higher clocked than the Atomic Pi (1.9Ghz vs 1.7Ghz) while same SoC and 4GB vs 2GB. The same form factor as RockPi4. I like the Atomic Pi, but it's a bit too big and could use a bit more performance. Have a great evening. Greetings. NicoD

🤯 Good to see you here, my friend. Been missing your reviews. Wondered whether you had fallen victim to COVID-19. Been up to my ears with RPi HQ cameras, stereoscopic vision, OpenCV, AI robotics, Jetson NX, & RPi CM3. Looking forward to RPi dropping the CM4 along with the inevitable variety of 3rd party carrier boards. Been eyeballing the Odroid N2 lately, so I'm looking forward to watching your review. 😎💨

@@TheOleHermit Hi, the N2+ review is online on my channel. I indeed had a sabbath. Didn't have new toys to play with and didn't feel good when locked down. I'm a bird that needs freedom. Greetings.

[@ExplainingComputers]

Hi Nico. It all comes down to software support, doesn't it? Always.

[@DeepFrydTurd]

Woah! M.2 slot on a SBC. Holy moly

[@TheOleHermit]

Khadas, NVIDIA, and Odroid also offer M.2 slots for NVMe SSDs.

[@itperdition]

They make a large heat sink for the 4c, I bought mine a month ago with the heat sink specifically for the 4c. Maybe your vendor doesn’t carry it or you were looking in the wrong place. I have mine booting off eMMC and it’s very quick. I bought this over the PI 4 because of all the storage and video connection options

[@ExplainingComputers]

This is great to hear. Not sold by Seeed Studio at present, which is where I got the board from.

[@Alberto_RiscvsCisc]

Great video ! Wanna see a speed test nvme.

[@josephtremblant2173]

Trickiest part I found is to configure/setup a m.2 NVMe drive. If you want to boot from NVMe on RockPi4C, only use approved Radxa Acer m.2 NVME drives: shop.allnetchina.cn/collections/rock-pi-4-accessories/products/acer-m-2-nvme-ssd-for-rock-pi-4 Don't forget the heatsink to keep it cool: shop.allnetchina.cn/collections/rock-pi-4-accessories/products/heat-sink-for-nvme-ssd-2280 Currently the fastest drive for RockPi4C is Samsung Evo Plus 970 NVMe. Unfortunately it doesn't boot from yet, Currently only five(5) m.2 NVMe drives are booting from RockPi4C: wiki.radxa.com/Rockpi4/FAQs#Which_M.2_SSD_are_supported.3F

Thanks.

Great update video as always 👍 Thanks for sharing 👍😀

[@yt3dkraft]

I would really appreciate if you could include testing camera and video encoding with these SBCs. Most of them have impressive specs but suck, when it comes to hardware acceleration support. In this regards, RasPi still is ahead of the crowd.

[@laxr5rs]

Thank you. I hope things are going well.

[@ExplainingComputers]

Thanks. Things are going much better for me right now :)

[@williamhart4896]

Nice looking SBC's waiting for rockchip to release the new octacore 3588 soc to the single board market . .. the dream would be if calvineum would put up a Thunder 2 chip as a arm desktop PC .

[@33lex55]

Great video, Chris! Makes me wonder how these SBC's compare to the Mainframes of the '70's (you know, those things, where a whole building had to be designed for it). Seems to me they've already surpassed those Million Dollar Babies...

[@ExplainingComputers]

Great thought. It is amazing what computer power sits in a credit-card form factor these days.

I have 2 of the model B with 4GB and I think they are great. Things they got right. CPU on the underside, makes for a neat and compact cooling solution. RPI could learn a lesson from this example. Generally well laid out and constructed board. The Rock64 3399 is fast and the options for NVMe and eMMc memory let you tailor your capacity and access speeds. Prices for accessories is more than reasonable for example the kit they sell for eMMc flashing has a nice USB3 speed and is cheap. Some meh attributes. Beyond initial basic stable OS choices not much seems to be happening on the development front. The orientation of the NVMe slot is backwards requiring a sub board sandwich. I can understand the decision, Radxa could not guarantee all NVMe drives will fit under the board with the heavy duty heatsink but a solution for a specified drive would be nice. Things that disappointed. The audio IO socket relies solely on the solder pads for retention, one of my boards had the socket break off whist plugging in a jack.(very tight socket) This lifted the pads on the board so now the board is effectively deaf and dumb to analogue audio. Audio over HDMI still works fine however. USB C power input is all the rage but a simple barrel socket is sturdier and power sources are more common. Things that caught me out. This board will not run on 5V via the USB C socket unlike the RPI so RPI PS's ( with a USB2 to USB3 adapter) will not work. Do not buy the RTC battery. Believe it or not the the simple mention of a battery in the packing list sends the freight companies into conniptions and I had to downgrade delivery speed with a refund for the lower class delivery. Just buy a battery locally and add your own connector. Soldering is the best way to connect the battery but the creative use of hot glue and heatshink should work fine for those averse to soldering. Being such a low power device I was leaving it powered on 24/7 when used as a Kodi player. Even with the large optional heatsink fitted, after prolonged use the heatsink got quite warm, not dangerously so but a concern none the less. Like I said overall I like these boards, good value, accessories and options are useful and cheap. If Radxa offered a single stack solution for the NVMe drive with the larger heatsink and improved the audio socket retention at a hardware level it would be a 10 but 8.5 with the quirks.
