This board does not have an MCU/SoC. It just has EPD driving circuit and the header for connecting your development kits.
The Touch Expansion Board for EXT3 (EXT3-Touch) opens a new dimension for EPDs. Instead of being passive, they can now act as input devices for any interactive interface, like Human Machine Interface (HMI) and thermostat. This is also a perfect configuration for ultra-low power IoT remote controls.
Note: this EXT3-Touch board needs to work with EXT3-1 board which is included in this kit.

Note: the 3.70″ Touch EPD is excluded in this kit. You will need to order it from here.
