This tiny board provides a 12-pin Pmod port, controlled over USB. <![CDATA[]]>Pmod<![CDATA[]]> 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:


<![CDATA[]]>Atmel SAMD21<![CDATA[]]> - Cortex M0+ microcontroller
<![CDATA[]]>Fairchild FXMAR2104<![CDATA[]]> - IO level shifter


Firmware bringup is in progress. It will work with the <![CDATA[]]>Tessel 2 JavaScript API<![CDATA[]]> and <![CDATA[]]>Signalspec<![CDATA[]]>.
