OrangePi Zero 3W Review: Tiny yet Powerful

The problem I personally have with OrangePi is that they maintain their own distro versions and do not upstream support as much as they could, either to kernel itself or to e.g. Raspbian.

The Allwinner A733 chip here is still pretty mediocre for upstream support. There's people working on it, but the Rockchip cpus have the benefit of having been around for a long long time & having had many years of support.

Down for me right now but usually https://linux-sunxi.org/A733 has ok details. Where-as collabora maintains this incredible support matrix, which generally indicates a modern want for nothing for Rockchip. https://gitlab.collabora.com/hardware-enablement/rockchip-35...

I still bought two allwinner a733 boards, on an AliExpress sale. I went with the Radxa Cubie A7z, as Radxa isn't perfect either, but much better ecosystem participants than OrangePi. https://linuxgizmos.com/radxa-debuts-raspberry-pi-zero-alter...
