Description:
The Nano R3 with CH340 is a compact, breadboard-friendly Arduino compatible board based on the ATmega328P microcontroller and uses the CH340 USB-to-serial chip for communication. This version comes unsoldered (i.e. without pin headers soldered), giving you flexibility to place headers or wires exactly as your project needs.
It is fully compatible with the Arduino IDE, supports all standard Arduino libraries, shields, and code. With 14 digital I/O pins, 8 analog inputs, and 5V logic, it’s perfect for small embedded & IoT projects.
