Zero 3E RK3566 4-core CPU SBC, GPU, NPU, HDMI with 1080P Output, and Gigabit Ethernet Single Board Computer (Radxa Zero 3E 2GB with GPIO)

Nice to have a board with the "pi zero" footprint but with much more power!It definitely needs to be said that if you are a Raspberry Pi enthusiast who has an interest in venturing out of the RPi Universe -- you should know up front that support is not a Google search away -- one of the strongest aspects of the Rpi boards is the robust community around it and the ease with which you can get support/answers for pretty much anything. This is, to date, an area that is lacking by comparison with boards like Orange Pi, Radxa, etc. That said, the Radxa discord is active and once you get your hands on a decent image (and a little experience with troubleshooting) these can be really great boards, and the Rockchip SoC's are getting more and more support, but you will likely need to be prepared to hold your own hand a lot more often. That being said, Radxa's discord is extremely active and an incredibly helpful community exists there.The current Armbian images for this board work incredibly well here, as does the Ubuntu images created by Joshua Riek, and there are options like DietPi as well, upon which you can build a solid foundation for whatever your project is for the boards. With the use of overlays, Raspberry Pi v1 and v2 cameras can be used with this board (Radxa official Debian and Armbian at this time). Octoprint installs without incident using the scripts provided on their github. the board will need heatsinks/cooling -- it does get hot, around 60+ with no form of thermal control, so that's a must. if you're just getting your feet weth with Linux and SBC's in general, you may wanna stay with Rpi until you have the basics down -- and many of the boards that were nowhere to be found during the shortage are back in stock.But if you're up to the challenge and willing to learn, or if you're looking for more power in a smaller footprint, I'd highly recommend these boards.

if you don't mind tinkering around to get things working, its priced very well, but beginners beware, this is not a raspberry pi. You will have compatibility issues, and you will have to find your own solutions. It was fun putting Armbian on it, the Radxa OS limits the CPU frequency by default. Unless you want to edit the device tree, you will be stuck at a frequency lower than what its capable of. However, with Armbian, your going to have to deal with even more compatibility issues, because its not their official OS.

Really like this SBC but it has some issues. Operating system support is weak. The vendor has issues with the images they generated for this SBC. One key issue, is this board has NO WAY programmatically to provide the board revision. Since RADXA often releases updates to their board designs over time, this is key to able to know which board revision you software is running on. The raspberry Pi devices have had this feature since day one all the way back in 2012, so this feature missing on this board is really odd and frankly a disappointment. The board not being GPIO pin compatible with Pi option boards, is not surprising given the different processor chip. But would have been nice if that was at least addressed in the documentation. There is no easy way to over come this limit, and in may cases if mapping the GPIO pins cannot be done given that RADXA design just is that different in reference to the GPIO assignments and processor limits. If you plan to develop your own software and/or your own boot image, this is nice board given its features, somewhat comparable to Pi Zero or other 'zero' boards. The onboard Ethernet (1GBE) is fast, faster than some other SBCs. But if you expect this board to be directly comparable to the Pi Zero line of boards, that is definitely not the case. In some ways better, better process, more memory, ethernet support! In some ways, not as great.

Works great for what I use it for (Pi-hole) . It's tiny and uses very little electric.

Was trying to use this with the linux g_mass_storage kernel module so I could use my NAS server on my Wii U. Radxa provides a guide specifically for setting up a previous Radxa Zero as a g_mass_storage module. It does not work with the Zero 3, or at least the debian image provided for the Zero 3 does not include the g_mass_storage kernel module. I've been waiting on an email from Radxa for 5 days, after the "Contact Us" said I would get a response in 48 hours

Excellent value.

This is yet another in the class of tiny single board computers and, on paper, seems to have a number of advantages. Faster processor, more power and more RAM, up to 8gb is available. It would be a great product if it wasn't so poorly documented and supported. The only useful option for an operating system is Debian, so you would need to configure this as any stand alone system. There is a command line version available but I couldn't get a connection to it so I needed a keyboard, mouse and monitor to use this. Since a general purpose computer is not the primary use case for systems like this, which commonly are used for automation, network duties and other dedicated applications, it isn't something I'm likely to look at again. When it starts to get support, including real documentation, it may amount to something, but not yet.
