Nano V3.0 CH340 Chip Board, ATMEGA328P. This Product Is A Lower Cost Version. The Only Difference Being That The USB To Serial Converter Chip Is The CH340 Instead Of The ATMEGA16U2 FTDI Chip.

Nano V3.0 CH340 Chip Board


The Arduino Nano with a CH340 chipset is a small, complete, and breadboard-friendly board based on the ATmega328. It has more or less the same functionality as the Arduino Uno but is in a smaller package. It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one. The Mini-B USB cable is supplied with the NANO
