Nano CH340 USB driver Arduino Compatible


Arduino boards have different kinds that fit different applications. One variety of these boards is the Nano. This board is compact and used for small-scale projects, but it also has the capabilities of an Arduino Uno. The primary differences between them are the size and the type of USB cable used for uploading programs.

This board has an integrated CH340 chip, which is also used in ESP boards and clones of the Arduino Uno and Mega. It has 22 I/O pins: 14 digital I/O pins, with 6 supporting PWM, and 8 analog input pins. It also supports SPI, I2C, and UART communications. Each I/O pin of the Arduino Nano can source or sink around 40mA of current.

This board operates at a voltage of 5V. It can be powered by an input voltage of 7V to 12V (recommended). The input voltage limit is 6V to 20V. The board has 32KB of FLASH memory, with 2KB used by the bootloader, and 1KB of EEPROM.

The board is programmable using a Mini-B USB cable. Unlike the Arduino Uno, it does not have a built-in DC jack for an external power supply. Powering it up is possible through its USB port or by directly connecting to the VIN and GND pins. Note that this board typically does not come with a USB cable.



  • Arduino IDE: Can be programmed using the Arduino Integrated Development Environment.
  • Bootloader: Comes preloaded with a bootloader that allows you to upload new code without an external programmer.
  • ATmega328P: This microcontroller is the brain of the Arduino Nano, providing the processing power for running your programs.
  • Auto-reset: Automatically resets the board when a new sketch is uploaded.
  • No built-in DC jack: Unlike the Arduino Uno, it relies on VIN pin or USB for power supply.
