Software
Rockchip provides Android 7.1 and Android 8.1 SDK with sources, Debian and
Ubuntu Linux distributions with all hardware accelerators working. The Linux
is not mainline.
Pre-built images are hosted at: http://images.olimex.com/release/rk3328/
We recommend the images to be written to SD card with minimum 16GB Class10
speed like: https://www.olimex.com/Products/Components/Storage/MICRO-SD-
CLASS10/

Power supply
RK3328-SOM requires +5V, 1A to operate. Do not apply more than 5V as this
would damage the RK3328-SOM.
The power supply is provided on pin.1 of the LCD connector.
Power consumption is: · around 0.4A during boot and idle · around 0.6A when
working at full speed · around 0.8A at stress
