Looking to build the smallest, most handy, bread-board friendly Arduino-compatible microcontroller? The Ardweeny from the Maker Shed fits on the back of the included ATmega328, taking up no more valuable breadboard space than the microcontroller itself! Just solder the seven components and pins to the PCB and the Ardweeny is ready to program with your FTDI cable. Perfect for embedded systems where room and weight is at a premium.
