ArmSoM-p2 pro is a compact Rockchip3308B-S SBC for headless applications
ArmSoM claims Debian 11 and buildroot support with OS images and some documentation to get started provided in a Wiki. But there’s something odd on the bottom side of the board… I can see a “Bpi” (Banana Pi) logo, and the ArmSoM-p2 pro is actually the same board as the Banana BPI-P2 Pro introduced earlier this year.
Further to this, they point out to SinoVoip (Banana Pi) store on Aliexpress to purchase the ArmSoM-p2 pro board, so I’d assume ArmSoM is either a subsidiary of Banana Pi or contracted by them to design some of their boards. Another interesting RK3308 board to point out, especially if you’d like an even smaller form factor, is the Radxa RockPi S SBC that was first unveiled in 2019 and is still sold today.
