What it does

The Arduino Nano R3 CH340 Soldered is a compact, breadboard-friendly microcontroller board based on the ATmega328P. Its small form factor makes it ideal for projects where space is limited while maintaining full Arduino Uno functionality.

Key features

  • 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)
  • USB Mini-B connector for power and data
  • Low power consumption suitable for battery projects

Good to know

  • Install CH340 driver before first use on Windows/Mac
  • Select ‘Arduino Nano’ and ‘ATmega328P’ in Arduino IDE
  • Same pin capabilities as Arduino Uno in smaller size
  • Some shields may not fit; use breadboard wiring instead
  • Soldered version comes with headers pre-installed
