RGB Tablets RK3399

The larger meeting room tablets run on a Rockchip RK3399 CPU. They are slightly better performing than the RK3288 CPUs, but the Android version is only available up to a maximum of Android 11.
The firmware is transferred in the same way as for the other tablets, using the RKDev tool. Instructions see below.
The reset button is located next to the Lan port.
