This tiny board provides a 12-pin Pmod port, controlled over USB. Pmod is a standard pinout for SPI, I2C, UART, and GPIO on a 6 or 12 pin connector, with over 100 modules available from several companies.
Level shifters and a digitally-controlled voltage regulator allow it to operate at 1.2 - 5V IO levels.
Key components:
- Atmel SAMD21 - Cortex M0+ microcontroller
- Fairchild FXMAR2104 - IO level shifter
Firmware bringup is in progress. It will work with the Tessel 2 JavaScript API and Signalspec.
