Arduino Nano ATmega328P 5V 16MHz CH340 USB Type-C Development Board – Unsoldered

Product Description

The Nano V3.0 ATmega328P Development Board is a compact Arduino-compatible microcontroller board based on the ATmega328P-AU. It provides similar functionality to the Arduino Duemilanove while offering a much smaller form factor, making it suitable for compact electronics projects, robotics, automation, and embedded applications.

The board operates at 5V and 16MHz and uses the CH340G USB interface controller for USB communication and programming. It can be powered through the USB Type-C connection, a regulated 5V external supply, or a suitable unregulated external supply through the designated power pin.

The board provides 14 digital I/O pins, 8 analog input pins, and 6 PWM outputs, along with a TTL-level RX/TX serial interface. It comes with a bootloader installed and supports programming through USB as well as ISP.

This is an unsoldered version, meaning the supplied header pins are not soldered onto the PCB. This gives users flexibility to install the headers according to their preferred orientation or directly integrate the board into custom PCB and embedded projects.
