SKU CH-D26J-08RZ8

ATmega328P microcontroller board with CH340 USB interface for Arduino Nano V3.0 compatible development

  • ATmega328P microcontroller powers Arduino-compatible projects
  • CH340 USB interface enables direct computer connection
  • 5 V regulator supplies stable breadboard power
  • Nano V3.0 form factor fits standard protoboards

ATmega328P CH340 Development Board

This board combines an ATmega328P microcontroller with a CH340 USB interface. It operates at 5 V and follows the Nano V3.0 pin layout. The compact form factor suits breadboard prototyping and embedded projects.

Practical limits of the Mini USB interface

The Mini USB connector supplies power and data but lacks the throughput of newer USB standards. Builders who need native USB device support or higher serial speeds will find this interface restrictive. Buyers who want more storage or multiple hardware serial ports cannot meet those needs with this board.

Highlights

  • ATmega328P microcontroller powers Arduino-compatible projects
  • CH340 USB interface enables direct computer connection
  • 5 V regulator supplies stable breadboard power
  • Nano V3.0 form factor fits standard protoboards
