Adafruit Metro 328 - Arduino Compatible with Headers

This is the  Adafruit METRO Arduino-Compatible - with headers.  It's a fully assembled and tested microcontroller and physical computing board with through-hole headers attached. The METRO works great with the Arduino IDE, and runs the ATmega328P at 16MHz so it is shape and pin-compatible with Arduino UNO R3 shields and boards. You can use this with the Arduino IDE (both desktop and cloud version) by selecting 'Arduino UNO' in the Boards menu. Need a power supply cable? Follow this link!
