Pinout & Pin Definitions

F1 Starter Kit Pinout Diagram

All IO pins on F1 Starter Kit could be MUX to any digital functions, while P19 and P20 are connected to I2C lane of the on-board fuel gauge.

Analog and touch inputs should only be used on analog pins.

The mechanical arrangement of the pinout is compatible to standard Arduino UNO shields.
