AOICRIE Board 340 compatible with offical (pack of 3)

• The is compatible with official board, using the same chips 340 with the official version.
• It is a smallest, complete, and breadboard friendly board. It has everything that official board has (electrically) with more analog input pins and onboard +5V AREF jumper.
• got the breadboard-ability and the Mini+USB with smaller footprint than either, so users have more breadboard space. It's got a pin layout that works well with the Mini or the Basic Stamp (TX, RX, ATN, GND on one top, power and ground on the other).
• can be powered via the Mini-B USB connection, 7-12V 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.

The is a small, complete, and breadboard-friendly board based on the . It has more or less the same functionality of the official for Arduino/Genuino, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.
