Crowd Supply ITACA Innovation uChip Microcontroller Board

Crowd Supply ITACA Innovation uChip Microcontroller Board is an Arduino Zero-compatible, narrow DIP-sized USB board. Based on the Microchip Technology SAM D21 Arm® Cortex®-M0+ Microcontroller, the uChip integrates 500mA boost and 1A buck converters and 14 I/O pins, two of which can be used for SWD programming and debugging. The tiny uChip can fit into a standard 0.3″ 16-DIP socket or plug directly into a breadboard, making it easy to integrate into any application.

The Crowd Supply ITACA Innovation uChip can easily be programmed using  BASIC, C/C++, asm, or CircuitPython.

With plenty of communication peripherals, low stand-by/run current consumption (270µA in standby when powered externally), and a compact size, uChip is ideal for IoT and battery-powered applications.
