Trivia Time!
When I got around to a project with this board it was missing the SY6280AAC low loss power distribution switch. Meaning the otg usb-c was dead. I missed the warranty period. Ameridroid great. Radxa bad.
When I originally ordered my Zero it arrived and was bricked. I contacted Ameridroid and they refunded me and I ordered again. The second time the device was just fine, I installed DietPi on it. I'm using a 1GB device with no eMMC. It works great as a combined PiHole and PiVPN server. It's functioned great in this capacity for nearly a year without issue.
Great board but, has limited hardware support and it's SPI implementation is flawed, it's 8 bits instead of 16.
Bought this guy with the intention of making into a mini-home server, mainly for Home Assistant, which worked well, I went through Radxa's wiki articles to install Armbian then HA on top of that and it all went pretty smooth, mostly just some small bugs to work around that I could easily google.
Then I got bored and opted to expand the scope and turn it into a proxmox server to run some other services like a fileshare and openthread, which it still works fine for but running into a couple of small issues that are more annoying than gamebreaking.
Now both Armbian and DietPi have official support for the Radxa Zero which should make things easier.
Pros
Tiny
Sips power
Moderately developed platform (Linux mainline kernel added support for this recently)
Great amount of processing power for the size and wattage
Can be powered by any USB charger, and the USB 3 port *does* support USB PD input, but it seems to do so only after it's turned on, and I haven't figured out a way to turn it on without plugging in the OTG power.
eMMC has better longevity than microSD
Cons
Not really any good case options, PiZero cases mostly work but not entirely.
Needs an adapter for microHDMI port, wish it could send display over USB-C.
Neutral
Only 4GB of RAM, I know it's a platform limit but more would still be nice.
Have been having some odd issues where it doesn't boot properly and not sure why, wondering if it's dropping to bootloader for some reason, might be my fault somehow.
While I'm not fond of the version of Android that comes default on the Radxa Zero, it's easy enough to reimage it. During testing with a USB-C hub and the WiFi connected, a couple of times during boot it exceeded 500mA at 5VDC. But most of the time during operation, it consumed 300-450mA. It seems to be stable and efficient. It is by far the fastest Zero-sized SBC I've ever tried.
