Description
[Arduino Boards] 🔷 Nano V3 CH340 ATmega328P Development Board (Soldered Headers) Compatible with Arduino ATmega328P CH340 USB Interface Compact Design Breadboard Friendly Ready to Use The Nano V3 CH340 Development Board is a compact and powerful microcontroller board based on the ATmega328P-AU microcontroller. Fully compatible with the Arduino Nano platform, it offers the same functionality as the Arduino Uno in a much smaller, breadboard-friendly form factor, making it ideal for embedded systems, robotics, IoT, automation, and DIY electronics projects. This version features the CH340 USB-to-Serial converter, providing a cost-effective and reliable programming interface. The board comes with pre-soldered headers, allowing it to be plugged directly into a breadboard or PCB without additional soldering. Powered by the ATmega328P running at 16MHz, the Nano provides 14 digital I/O pins, 8 analog input pins, 6 PWM outputs, and supports communication protocols including UART, SPI, and I²C. The onboard bootloader allows programming directly through the Mini USB port using the Arduino IDE. The Nano can be powered through the Mini USB connector, an external 6–20V DC supply, or a regulated 5V input, with automatic power source selection for seamless operation. Note: Some computers may require the CH340 USB driver before the board is recognized.
