The DFRduino Nano USB Microcontroller V3.1 ATMega 328 is a breadboard ready version of the Arduino mini with integrated USB.

The arduino Nano has everything that the Diecimila has electronically with more analog input pins and an on board 5V AREF jumper. The arduino Nano automatically senses and switches to the higher power supply, so there is no need for a power select jumper.

The nano's pin layout works well with the Mini or the Basic Stamp TX, RX, ATN, GND on one top, power and ground on the other .

The DFRobot DFRduino Nano USB Microcontroller V3.1 ATMega 328 can be powered via the mini B USB connection, 6 20V unregulated external power supply pin 30 , or 5V regulated external power supply pin 27 . The power source is automatically selected to the highest voltage source.
