Nano USB C V3.0 ATmega328P CH340G 5V

$12.95 (AUD)

The Pro Micro is similar to the Pro mini except with an ATmega32U4 on board. The USB transceiver inside the 32U4 allows us to add USB connectivity on board and do away with a bulky external USB interface.

Nano USB C V3.0 ATmega328P CH340G 5V is a surface mount breadboard embedded version with integrated USB. It is the smallest, complete, and breadboard-friendly. It has everything that Diecimila/Duemilanove has (electrically) with more analogue input pins and an onboard +5V AREF jumper. Physically, it is missing a power jack. The Nano is automatically sensed and switched to the higher potential power source; there is no need for the power select jumper.

It is two layers. Nano’s got the breadboard-ability of the Boarduino and the USB C with a 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). This new version 3.0 comes with ATMEGA328, which offer more programming and data memory space. That makes it easier to hack and more affordable.


  • Microcontroller: Atmel ATmega328
  • USB Controller: CH340G
  • USB C
  • Operating Voltage (logic level): 5 V
  • Input Voltage (recommended): 7-12 V
  • Input Voltage (limits): 6-20 V
  • Digital I/O Pins: 14 (of which 6 provide PWM output)
  • Analog Input Pins: 8
  • DC Current per I/O Pin: 40 mA
  • Flash Memory: 32 KB (ATmega328), of which 2 KB used by the bootloader
  • SRAM: 2 KB (ATmega328)
  • EEPROM: 1 KB (ATmega328)
  • Clock Speed: 16 MHz
  • Dimensions: 44mm L x 18.5mm W x 20mm H

This is a small, complete, and breadboard-friendly microcontroller board based on the ATmega328. It has the same functionality as the Arduino Uno but in a smaller physical package. The main difference is the lack of a DC Barrel Jack and the substitution of the square Type-b USB connector for a  USB C connector.


Package Included:

  • 1 x Nano USB C V3.0 ATmega328P CH340G 5V

Development  Resources: demo codes, schematics, datasheets, etc
