The Cuttle is a bare-bones, Arduino-compatible, soldering kit from Boldport, based on the concept of shrimping.it. 

The Cuttle was first designed by Boldport as commissioned work for Embecosm, who made it open source hardware.

The microcontroller comes with an Arduino bootloader on it, but you'll need a serial programmer to load Arduino sketches to it. The programming header holes are staggered so that it can be removed after programming. Once assembled, the board fits on a breadboard for easy prototyping.

Note: requires through-hole soldering!

The Cuttle was project #6 of the Boldport Club.
