RGB Tablets RK3399

The larger meeting room tablets run on a Rockchip RK3399 CPU. They offer slightly better performance than the RK3288 CPUs, but the Android version is only available up to Android 11 at most.
The firmware is transferred in the same way as with the other tablets, using the RKDev tool. See below for instructions.
The reset button is located next to the LAN port.
