What it does

The Arduino Nano R3 CH340 Un-Soldered is a compact, breadboard-friendly microcontroller board based on the ATmega328P supplied without soldered headers. Its small form factor and unpopulated pins make it ideal for custom permanent installations and space-constrained projects.

Key features

  • Un-soldered headers for custom wiring and permanent installation
  • Compact size (45mm x 18mm) fits standard breadboards
  • ATmega328P microcontroller with full Arduino compatibility
  • CH340 USB chip for programming and serial communication
  • 22 digital I/O pins including PWM and SPI
  • 8 analog inputs (2 more than Arduino Uno)
  • Low power consumption suitable for battery projects

Good to know

  • Headers not included – solder your own or wire directly
  • Install CH340 driver before first use on Windows/Mac
  • Select ‘Arduino Nano’ in Arduino IDE
  • Requires soldering skills for header installation
  • More durable for permanent/vibration-prone installations
