Android mainboards, documented down to the pin
Our KTM boards run Android on Rockchip RK3588, RK3576, RK3568 and RK3566 chips, plus RK3399, RK3288 and Amlogic T982 for existing designs. Every board has a public page with its connector map, pin table and serial ports, and ships with rooted firmware and a system API — so you can start developing before you place an order.

FAQ
Can I read the documentation before buying a board?
Yes. Every KTM board has a public wiki page with its pin table, serial map and firmware guides.
Which Android version does each board run?
From Android 7.1 (RK3288) to Android 14 (RK3576, RK3566). See the board table in the wiki.
Do I need platform signing to control the hardware?
No. Our firmware is rooted, so a normally signed APK can call the full system API.
Can I buy a board without a display?
Yes. Every board is sold on its own, with the same firmware and API as our finished devices.
