Nano R3 CH340 Development Board – Arduino Compatible (No Cable)
Nano R3 CH340 Development Board – Arduino-Compatible ATmega328P Board (No Cable)
The Nano R3 CH340 is a compact, breadboard‑friendly microcontroller board built around the ATmega328P. It is fully compatible with the Arduino Nano platform and uses the CH340G USB‑to‑serial chip for stable programming and serial communication. This board is perfect for prototyping, robotics, and IoT projects where space is limited and reliability matters.

Compatibility
The board works with all standard Arduino Nano shields and 5V sensors. It is programmed via the Arduino IDE after installing the CH340 driver (available for Windows, macOS, Linux). Common pairings include breadboards, jumper wires, ultrasonic sensors, and servo motors.
Wiring Notes
Power the board through the Mini‑B USB port or apply 7–12V to the VIN pin. All I/O pins operate at 5V logic levels; use level shifters when connecting to 3.3V devices. The CH340 chip is auto‑recognized on most systems, but manual driver installation may be needed on older Windows versions. Current per I/O pin is 40 mA max.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino IDE?
Yes, it works seamlessly with the Arduino IDE. Simply select “Arduino Nano” under boards and install the CH340 driver if needed.
Does it require soldering?
No, the board comes with pre‑soldered male pin headers, so you can plug it directly into a breadboard or use jumper wires.
What is the difference between CH340 and FTDI chips?
Both are USB‑to‑serial converters. The CH340 performs the same function as FTDI chips but at a lower cost; it requires a driver installation to appear as a COM port.
