Build Faster with the Nano V3.1 by DFRobot Arduino Compatible

Nano V3.1 by DFRobot Arduino Compatible - The Nano V3.1 by DFRobot Arduino Compatible is a breadboard-ready version of the Arduino mini with integrated USB. The Nano has everything that the Diecimila has (electronically) with more analog input pins and an onboard +5V AREF jumper. The 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 Arduino Nano V3.1 DFRobot 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 as the highest voltage source.
