The Raspberry Pi Zero 2 W review

I got my hands on the Raspberry Pi Zero 2 W. It's more than twice as fast as the original Pi Zero and Pi Zero W, but what other secrets does it hold?
I X-rayed it to find out what's inside this little Pi! It's not cheap making these videos, so if you like them, please consider supporting this channel:

I know this advice doesn't help most people, but for those living in the UK and are willing to go to Cambridge the official Raspberry Pi shop seems to have a stockpile. Accidentally found it when visiting a month or so ago and was surprised to see stock, they do limit how many you can purchase though.

so funny lol

[@Debloper]

This will fit perfectly for purposes where ESP32 doesn't cut it (you need a general purpose OS for flexibility in your project), and a full Raspberry Pi is an overkill (either from compute or cost perspective). For e.g. as an infra/SRE guy, I want to use half a dozen of Pi Zero 2 to drive (old/salvaged) LCD screens all around my home to display various dashboards & notifications, so I can spend time with my family better without having to constantly check my phone or run to desk intermittently to check for incidents. If I can actually get my hand on any of those, that is...

[@andreamitchell4758]

how would economically get a salvaged LCD screen connected to it though? assuming there is no composite or HDMI in

[@thermostance1815]

​@@andreamitchell4758the LCD interface has a spi port plus a video interface such as LVDS, RGB, or eDP. It wouldn't be *too* complicated to go from hdmi to one of those. Probably would need a custom PCB.

[@John.0z]

To me, this is just highlighting how late the release version of 64bit RasPiOS is! Now there is even a Zero-sized board that could benefit from it (with care about RAM usage).

[@JeffGeerling]

I'm hopeful the 64-bit Pi OS build will become the default sooner or later. The Zero is the last of the boards that didn't have proper 64-bit support...

[@thewiirocks]

@@JeffGeerling That’s because the old Zero was an ARM 7 32-bit chip incapable of running modern ARM instructions. That’s been a huge challenge trying to find software that’s still buildable and functional on such an old instruction set, even if I pulled 32-bit compiles. To get Docker containers working, I pretty much had to run HyperiotOS as the only option. And then there were only a handful of software packages that worked, mostly compiled by Hyperiot. Once I found a working JVM I could run Java software. But that was painful on a CPU that underpowered. So this upgrade was long overdue as the old hardware was quickly growing useless.

[@ernestgalvan9037]

@@thewiirocks ..”the old hardware was quickly growing useless “ to YOU, mayhaps… But there are plenty of us out here that are running use cases (power budget) that run FINE on the “old, useless “ hardware. Software has been written, and validated. Now, having NEW hardware at the same price point AND power budget… then yes, it’s gonna be an easy (easier?) upgrade path,,, And making the case for the ‘old’ hardware more difficult to support… ARM7 to ARM8 is a major stepping stone in terms of software support.

[@stephenvalente3296]

Think that’s the one given now the Pi Zero 2 has a custom in-house SOC. Still hoping they make a more daring choice to produce a “pro” Pi 5 with a different footprint, maybe up to the size of the CM4 I/O board to allow more headroom for advanced features.

A beefed up CPU would probably really help here!

Hi from the UK, another great video Jeff. Knowing it can run 64 bit is incredibly useful. I run either Ubuntu (64 bit only) or Raspberry Pi OS 32 64 bit on my Pi 4Bs depending on the use case. The 512 MB RAM is likely to be a limiting factor but in time hopefully falling memory prices will give us a 1 GB version. For £13.50 at the Pi Hut in the UK it is priced cheaply enough that it can be bought to just ‘play with’. Looking forward to the next video.

[@davidmalkowski7850]

This is perfect for my needs! A while back, PRUSA of the MK3S fame released a guide to attach a Pi Zero directly to their Einsy RAMBo board in a seamless case solution. Just one problem: the Zero could run OctoPi okay by default, but attaching a camera caused things to explode in a hurry. Even with the same amount of memory, the 02 should have more than enough processing power to run OctoPi with a camera streaming at the same time. I'm sold!

[@JeffGeerling]

Yeah, this little guy is ideal for use with 3D printers, though if you stream the camera feed, consider backing it off the 480p

[@davidmalkowski7850]

@@JeffGeerling Oh no, the stream will be 480p, but ideally I want to attach a USB webcam for Octolapse streaming as well. My machine has the MMU2S, which means I want a camera on the selector. Maybe I should jerryrig a servo HAT in there to slide the camera up and down in it's enclosure?

On the original Pi Zero W it made a difference to disable USB power. You might try that too, if you're looking to present minimum power requirements. I used a Pi Zero W in a "Linux on Solar power" project. It turned everything off and only woke up every minute to record solar power stats from the Solar Charge Controller.

[@charlesjmouse]

Finally! Yes it would have been much better with 1Gb of RAM but I'm not going to complain. Ever since faster Pi's became a thing sufficient power in the smaller form factor versions to actually be useful as something more than a glorified microcontroller has been a glaring omission. Now if the Raspberry Pi foundation could finally, finally, come out with an "A" model that contains the Pi 4 SoC I'd be delighted! No, no, no, the Compute Module is not a reasonable alternate for those wanting a Zero with a bit of 'grunt' or an "A" of equivalent power to the Pi 4. Once you have factored in the inevitable IO board it's too expensive for most people's projects and when coupled to any IO board that has a useful range of ports you end up with something larger than a Pi "B" anyway. PS If there really is to be no "A4" I would really appreciate the option to buy "B4s" with the connectors and GPIO supplied separately. Being able to ignore what you don't need or mount connectors remotely would be a real boon to those of us who are forever disordering stuff from their new Pi's.

You mentioned the Kubernetes cluster; I just made a docker swarm cluster using 3 RPi Zero 2 W. The catch is that you will need to use ARMv7 as your base image for your containers. But it's incredible to see such a tiny PCB perform much. 😁

[@619easyfix]

Thanks for show us the Zero2! I have original Zero W running my DNS server and went with it over a full Pi because I liked the smaller power usage with it running non-stop, so that was nice to see you captured the 2's power as well. I am curious thou how did you get the speeds for a wired connection, should I assume you connected an USB to Ethernet adapter to it or is there another option to add a wired connection to the Zero I have overlooked? 👀

[@AudreyRobinel]

Hello Jeff, nice video as usual! :) I paused mid video to order one, should be shipped soon :) I like that with the raspi foundation, you don't expect anything, then boom! new board! However, it is becoming more expensive and difficult to try to "catch em' all"... anyways, that is a great new board, will be perfect for HQ cam builds! In order to compare efficiency, it would be interesting to compare the energy used for a fixed compute task. For instance, transcoding a X Gb file on both, and see the Wh consumed. The zero 2 might draw 2 times more, but for much shorter (less than half the time) , thus using less overall energy. But i think that the idle power draw will still keep a place for the original zero W on battery.

[@TheOleHermit]

Interesting food for thought, but not as much as CM4, IMO, which offers full Pi functionality + a wide variety of carrier boards, a small form factor, and lots more bang for admittedly a lot more bucks. But, how much is one's time worth, while building a project? Good call on Radxa's competitor. Fell for the specs of their Rock P4b a few years ago, especially with it having the M.2 NVMe connection. But. alas, just as you mentioned, their OS wasn't stable, it was plagued with bugs, and there was only a small specialized volunteer support community. Even after investing into building a custom aluminum case, w/Noctua cooling, I was forced to give up in frustration, When it comes to Linux, I'm more of a Redshirt Jeff kinda guy, enough brains to be dangerous and constantly getting into trouble. So, my $300 ROCK P1 4b project has only been collecting dust on the shelf for 2 years. Lesson burned in memory. Fooled me once...

[@JeffGeerling]

I have a couple Banana Pi and one ODROID unit collecting dust over in my electronics pile for the same reason :(

[@eddycolangelo]

Yeah, I'm ashamed to admit it, but same here with the NTC CHIP. Support used to be great but now it's a mess, almost non-existing, basically I have to rely on old documentation and reddit whenever I have a problem. Couple that with the software and even hardware issues that are popping up left and right and now I have a huge pile of pain to go through every time I want to try and do something with it, so it inevitably ended up collecting dust in a drawer. So yeah, I really wish I went with the Pi Zero instead of this, I wish I had not allowed the spec sheet to push me into this purgatory. No amount of storage, ghz or wi-fi was worth the time and energy I had to waste on this thing just to make it work.

[@thewiirocks]

@@JeffGeerling I tried getting a Banana Pi Zero to replace the underpowered Rasp Pi Zero. OMG. The thermals were out of control on that thing! Absolutely useless board and I managed to burn myself playing around with adding a heat sink. Which did nothing, BTW. Idling produced too much heat for the thing, much less any serious workload. And trying to figure out a fan for that’s form factor just wasn’t worth it. I’m sticking with Pi Foundation. The hardware may not be the fastest, but it’s well built and balanced.

[@paulmichaelfreedman8334]

I bought an Orange Pi PC2 some years ago (2016 I think), and remember that I could not get it to boot. Support for that board was lacking for quite a while. It wasn't until after about two years that I got it to actually run GNU/linux. Now it's running as an openvault server.

Great video 👍. If I used this to replace the Zero in the web cam project, would it handle 1080p?

[@DelGray]

I'm with ya on usb-c. Kinda annoying having to solder my own USB with C connector onto my PI Zeroes. I get that it's probably cheaper and you don't get high-speed USB but it saves so many headaches as I only have usb-c hubs that provide power, data and network than I've ever owned that are micro compatible.

[@stheil]

Yeah even ignoring all the high-speed and alternate modes that the Zero can't do, just the physical USB type C connector would be great to cut down on the number of different cables to keep around.

[@Voyajer.]

I needed a micro-usb cable with data recently, I think I found my only surviving one after finding all of my other non data-capable ones first. Not having to worry about that anymore (as much) would be fantastic.

You can try to sand down to 2-3um higher than last element/connecting wire to increase thermal conductivity and cool the whole package, since the cpu under the memory will heat up the memory which will show those weird errors that probably did...

Those x-ray pics are amazing. And, you have an x-ray machine??

[@JeffGeerling]

Haha, I wish! I actually worked on getting an old dental X-ray for this, but in the end found the resolution wouldn't have been very good. So I worked with a professional electronics inspection company instead. Their CT machine cost over $500k!

Really excited about these new units, I can't wait to give one a shot, but I am a little worried about how available they're going to be, CM4s and the normal Zero W are both still very hard to find due to limited supplies, and if anything adding a new unit to their product catalog will only hurt that further unless they're also seriously upgrading their manufacturing capacity.

I'm glad they gave the new zero 4 cores, 512mb of ram seems like limitation, I'm wondering if swap could help, but might be too slow
