Initially it will use a SNAPZZ M.2 Module (ESP32 or PICO2040 based) as it's MCU.
The BETA only exposed I2C (STEMMA QT) externally but ultimately i will expose the remainding GPIO (which is a lot) from the MCU Module. So MAKERS can attach their favourite thing.
The Display brainwork is done by a Bridgetek Display processor that is driven only by SPI protocol and talks RGB to the Display.
Unfortunately my square friend has no name yet :-( which is also something i need to fix ASAP.
7.April: PCBs and Components are ordered. Will update after BETA is alive.
