Arduino Nano Tutorial - Breakout Board with 2A SMPS #1

One thing the Arduino Nano lacks is a 2.1mm power socket for supply voltages higher than 5v. The standard Nano breakout board has that 2.1mm socket, but doesn't offer any additional current availability - 5 volts still comes from the small analogue regulator on the back of the Nano PCB. But I've found a Nano compatible breakout board complete with a 2A switched mode power regulator. It's actually designed for the Arduino Micro (a breadboard friendly Leonardo), but the Micro and the Nano are largely pin compatible.
