That new engineer has had one hell of a good first 12 months with RPi. It has been proven once again that one of the most important things a company must do is to hire the right talent.

[@pipsqueak2009]

I went to the same school (St Albans School), and worked at a local TV repair shop on Saturday mornings (Colbourn Electronics on Folly Lane - with Graham Colbourn) with Dominic back in the early 90s.... He was a year or two above me - and I remember he was a very talented electrical and software engineer even at the age of 15. I was a complete numpty by comparison..... It's great to see him still doing amazing work at the Raspberry foundation - Hi Dominic!

[@NikitaLab]

Finally easier PCI-E access, this is great

[@lucmorvan1867]

Can you make another short video to explain my wife why I absolutely need it, on top of my existing Raspberry Pi herd? This would save me a lot of trouble 😂

[@vwtch]

Back in the day I used to have to take out a rather significant bank loan to buy a computer. Over the years I have spent far more money on computers than I paid for my house.

[@jyvben1520]

yeah, not so cheap when getting cm4 and dev board and "industrial powersupply/poe hat+poe switch" and antenna kit , but still interesting for the dual camera option. might need cooling fan ...

[@arnitdo]

The PCI Gen2 x1 slot is going to be very useful for mass fast storage, like an NVMe SSD

[@zungaloca]

nvme really?

[@marslif]

But does the SoC even support NVMe? Also, PCIe 2.0 x1 is 500MB/s, slower than USB 3.0 so i don't see the point...

[@travis1240]

@@zungaloca yes. Its proven to work and work well

[@travis1240]

​@@marslif Theoretically you're going to get slightly better throughput on the PCIE bus than USB3.0. They actually have the same theoretical throughput limit, but since in the RPI the usb chip is behind the PCIE 2.0 x1 bus, you have to add a translation layer with no possible speed increase. Practically, putting an NVME board on the PCIE bus is a simpler translation than going from PCIE->USB3(host)->USB3(client)->(SATA or NVME).

[@jyvben1520]

that card uses a bit more than x1 i expect, also needs a pc powersupply, not impossible but highly unlikely

[@ygrittesnow1701]

@@jyvben1520 If I remember right didn't they say this board could accommodate up to a 24 v power supply for industrial applications? If that is the case, don't see a reason why this might not be able to handle a RTX 3090 provided you can work out the problem with the PCIe connector limitation. I am just learning a lot of this so forgive this for what it is. The GPIO handles varying voltage outputs yes? Would it be unrealistic to make a GPIO to the power connection on the 3090?

[@ErilynOfAnachronos]

I doubt the board can handle 15 Ampère, so an additional power supply will be necessary. I assume someone will get it working, but with a huge performance penalty due to bandwidth limits. So no, it can't run Crysis. 😜

[@_tsu_]

Most likely not. Nvidia's drivers are binary only and closed source. They don't have an ARM version for Linux yet though that is somewhat likely to change(don't keep hopes up). HOWEVER, AMD has open source drivers so you might be able to plug a Big Navi card into it though you may need(or may not) a pc power supply

[@scotty3114]

It has become clear that the Free Software approach, applied to both software and to hardware, is the only platform which has the ability to prevail over the long term.

[@IAmNumber4000]

Microcomputers like this are going to be a BIG deal. All the difficult design work is in that processor and that board, this frees up PCB makers to do a lot more in a lot less time.

[@madman1027]

This range is utterly fantastic!! I can also see this being popular with people for media players/games consoles

[@smorrow]

Yeah. The Slice media player already used the original Compute Module.

[@smorrow]

Good for laptop sleepers too. If anyone reading this wants to make an OLPC XO-1 sleeper, I will buy it. I'd like to give my XO to my nephew, but it's too old and slow, right now.

[@alexdiamantopoulos6614]

I like the antenna connection with a wire attached. We use computers in basement when routers are upstairs. And external cable attached makes it better WiFi connect.

[@williamlazenby314]

Exactly what I need for several projects.

[@ygrittesnow1701]

The IO board is brilliant. As long as future modules maintain the same form factor, all you would have to do is upgrade to the next gen board and keep going. The only downside to losing the DIMM side is there are a few products that just came out that depend on that interface. Be nice to see a second iteration of the CM4 come with the same DIMM interface or at least another board that it can connect to. Maybe a DIMM adapter that will fit the PCIe 1 slot to carry over.

[@logtothebase2]

Surely Eben knows the answers to all these questions already.

[@edmondVerboseLogging]

with these new interface for CM4, it will be very hard to stack multiple CM4 in a single compact interface board (Cluster).

[@YuriG03042]

New boards will be made to accommodate this

[@W1ldTangent]

I've already seen a carrier board that the CM4 snaps onto and then allows you to slot it into an edge connector like the previous modules.

Will there be ready-made cases for it?

[@Jayanky]

I don't think there will be as many ready-made cases as much as kits that include the CM4. The CM4 is designed to be fit into another PCB instead of just being self-contained.

[@smorrow]

@@Jayanky I think "it" here meant the I/O board.

[@theengineer9910]

Raspberry pi and arduino are responsible for my love for electronics, everything embedded and Analog. But my love for building started with wanting my own arcade machine.

Do you have any plans for adding PCIe boot to the CM4?

[@petermichaelgreen]

Someone asked on the forums about NVMe boot and was told it was on the todo list but other things were ahead of it.

[@mickfreeley6054]

To use a baseball expression, the RPi Foundation has really 'hit it out of the park' recently with the CM4 and the RPi 400 - standing ovation !! The CM4 I/O board is a great companion but I consider it a version 1 product. I really hope that a newer version will include all USB3 ports and PCIe v3 x4 which almost all NVMe flash storage cards are designed to. Due to the published CAD files other vendors probably have this in the works already. Also looking forward to HATs and cases that will make multiple drive (say RAID 6 HDD) NAS solutions possible.

[@hooooooooz]

Like it and look forward to using it in our product next year.

[@whothefoxcares]

Who has visions of *Hackintosh* running on Raspberry Silicon?

[@Kabodanki]

Hackinstosh run on x86 hardware, because x86 is extremely backward compatible, stable, standard, in fact cost of supporting old instructions for x86 is among other thing are things that slows down x86 in front of ARM that doesn't have such things to support. So in fact next version of Mac won't run at all.

[@Lp-ze1tg]

The quality control of the emmc is very important.

[@wskinnyodden]

Make an expansion board designed specifically for making tablets and sell it together with a touchscreen with at least one camera on it. Of course this board must have battery support and can discard ethernet in favour of some other nicety. And the PCIe must be converted into a MiniPCIe slot like on them laptops. And bang, you have entered the Tablet market big time.

[@W1ldTangent]

The only possible problem I see with this is having to use the built-in PCB antenna of the CM4, since you wouldn't want to stick that u.FL bulkhead connector on your tablet, or re-certify it with another. Here's hoping RPi Foundation will make another u.FL option with a flat antenna you can stick inside the casing like laptops have.

[@Sembazuru]

AFAICT, "all" that one would need to do is design a case for the existing R-Pi 7" screen that would hold at least 1 r-pi camera (maybe 2 for front and back cameras?) and the CM4-IO board. Might be a bit thick tablet with all the IO connectors on the existing CM4-IO board... But it is doable.

[@ThaRealChuckD]

Does the wireless support monitor mode?

[@bananaman2184]

What are the limits of this? Is it possible to design a board for the CM4 to have ram slots?

[@ygrittesnow1701]

Question. Very undecided as to which to get. Looking at the new Raspberry Pi 400 and the new compute Module 4. Obviously the Pi 400 needs no case, however the computer module and the IO board are so incredibly new, are there any dedicated cases available for this?

Hi RPI guys, just wondering if you will produce GPIO-only dongle for this module without any need to use mother board. I need more powerful substitution for RPI Zero W with at least 2GB of RAM, but I don't need any PCI-X or HDMI or USB ports from your mother board for CM4. Or maybe you've got some plans to substitute your legacy RPI Zero W with something modern and more powerful?
