Arduino Nano v3 Compatible

ATmega328 with CH340G and Micro USB

Note: This model has been discontinued and is replaced by a USB-C and different Micro USB model.

This Arduino Nano-compatible module is a small, complete and breadboard-friendly design. Designed around the ATmega328, which is the same as the original Arduino Nano 3.x. It has more or less the same functionality as the Arduino Duemilanove, but in a different package. It lacks only a DC power jack and works with a Micro USB cable instead of the less common Mini USB..

For added protection, the board has an auto rest fuse to protect the on-board electronics.

Technical Specifications

Microcontroller: ATmega328
Operating Voltage: 5V DC
Input Voltage (recommended): 7-12 V
Digital I/O Pins: 14 (6 provide PWM output)
Analog Input Pins: 8
DC Current per I/O Pin: 40 mA
Flash Memory: 32 kB (2 kB used by Bootloader)

Unlike the original Arduino Nano v3, the USB interface used a Mini USB B connector. This new design uses the more popular Micro USB B connector.

Note: This unit includes two headers of 15-pins and the six pin expansion connector. These will require soldering on to the processor Nano board.
