NANO R3 CH340 development board with ATmega328 microcontroller chip without cable (Unsoldered)

The NANO R3 CH340 Development Board is a compact, affordable, and breadboard-friendly microcontroller board based on the ATmega328P chip. Designed for minimal space projects, it offers the full functionality of the Arduino UNO but in a much smaller form factor.Unlike earlier models using the FTDI chip, this version utilizes the CH340 USB-to-Serial converter, significantly reducing the cost without compromising performance. It supports USB programming and external power options, making it ideal for DIY electronics, robotics, IoT projects, and embedded systems.It connects via mini USB, and automatically selects the highest voltage source between USB and external power, ensuring reliable operation.

Features:-

•  Support USB download and power
•  Support for external 5V to 12V DC power supply
•  It supports power supply by 9V battery
•  Support ISP download
•  Automatic reset during program download.
