Good value for money!
Great little board, can do quite a bit. Will need decent cooling and is a little more hassle to set up then a traditional RaspberryPi. Will serve a good range of uses!
Good value, works well and easy to get going
Great board, only had it for a day. No plans to work it really hard, but running DietPi using a micro SD card got it up and running first time headless without issues. Forgot to get a mini-HDMI cable, so waiting for that to test with a display, but using it as a USB serial controller is great.
Great for the price.
Great if you have even a rudimentary knowledge of SBCs. Unfortunately not as supported as Raspberry Pi's (I mean, what is?) but as mentioned the DietPi images work great, well optimised. Only problem I have (aside from the odd Radxa wiki) is the cpu temperature tends to run hotter than raspberry pi's. I recommend pairing this with the Heatsink Case from Jaycar (CAT.NO: XC9112) to keep this unit cool and ventilated. That said, it has more grunt than its rapberry counterpart, so it's to be expected.
Steer clear of this
Very poor. There are almost no images that work as an OS for this, and those that at least start have the display blinking on and off. Mine now has no video output at all, so that has failed. This product is far from "reliable".
Nice and cheap SBC, Easy to setup
Excellent board for a pihole, unbound and tailscale setup installed dietpi and was able to setup everything headless.
