Arduino-compatible Nano V3 Development Board (ATmega328P-AU)

The Nano V3 is a compact and versatile microcontroller board based on the Atmega328P-AU microcontroller running at 16 MHz. It features a Mini-USB port for programming and power and utilizes the WCH CH340G USB-UART chip for reliable driver compatibility across various operating systems. This version boasts enhanced voltage regulation compared to the standard Arduino Nano, offering improved stability for your projects.

Key Specifications:

  • Microcontroller: Atmega328P-AU (16 MHz)
  • Flash Memory: 32kB (2kB bootloader)
  • SRAM: 2 KB
  • EEPROM: 1 KB
  • Digital I/O Pins: 14 (PWM capable)
  • Analog Inputs: 8 (10-bit resolution)
  • DC Operating Voltage: 6.2 – 15V
  • DC Output Current (5V): 1A Max
  • Communication Interfaces: Serial, SPI, I2C


  • Compact Design: Ideal for projects with limited space constraints.
  • Wide Operating Voltage: Accommodates various power supplies (6.2-15V).
  • Enhanced Voltage Regulation: Improved stability compared to standard Arduino Nano.
  • Driver Compatibility: Utilizes CH340G for reliable driver support across operating systems.
  • Rich Feature Set: Supports analog/digital I/O, PWM, SPI, I2C communication protocols.

Pin Functions:

  • Digital Pins (0-13): Configurable for input or output (5V logic). Each pin can provide/receive up to 40mA and has an internal pull-up resistor (disconnected by default).
  • Serial (0 – RX, 1 – TX): Used for TTL serial communication.
  • External Interrupts (2, 3): Configurable for interrupt triggers.
  • PWM (3, 5, 6, 9, 10, 11): Provide 8-bit pulse width modulation output.
  • SPI (10 – SS, 11 – MOSI, 12 – MISO, 13 – SCK): Enables Serial Peripheral Interface communication.
  • I2C (A4 – SDA, A5 – SCL): Supports inter-integrated circuit communication.
  • AREF: Analog reference voltage for analog inputs.

    Super, rien à redire, il fonctionne à la perfection. Il vaut mieux payer un peu plus chère et avoir un clone de très bonne qualité plutôt qu’un one chinois sur Ebay qui va marcher deux jours. En plus, il y a des leds et une carte des valeurs de résistance qui vient avec en cadeau.

    A good buy in my opinion. All the units tested as good. I didn’t need any “special drivers” to make them work.I liked that the headers were not already soldered in because I use ribbon cable to connect with other devices in the projects.I would buy from this company again.

    As far as I can tell, this is functionally identical to an “official” Nano. It looks and works fine. You do have to solder the pins on, but I didn’t want them on anyway so prefer it this way.
