Runwelltec RWA027 RK3588 SBC Rockchip RK3588 digital signage display board

The company provides Android 12 with Linux 5.10 for the board, but there’s no mention of support for any Linux distributions. I’d assume it could be done upon request. It’s quite a versatile Rockchip RK3588 single board computer so besides applications like digital signage displays and network video recorders, it could be found in all sorts of more advanced applications.

I don’t think I had ever written about this company before. Runwelltech has a website, but it has not been updated for several years, so most of the information comes from an Alibaba page that shows a $186 price tag for samples as well as a PDF user manual with additional technical information.
