A few days ago we saw what would have been a killer Kickstarter a few years ago. It was the smallest conceivable ATtiny85 microcontroller board, with resistors, diodes, a USB connector, and eight ...

Just how small is the Micro? It measures in at 1.9-inches x 0.7-inches (48mm x 18mm). The board is based on the ATmega32u4, and has a built-in USB. It features 20 digital I/O pins, seven of which ...

Another advantage is the small footprint of the Narrow boards. They are approximately 1/5 the size of an Arduino Mega 2560 board, making them perfect for projects where space is a constraint.
