Description;

The Nano Board R3 with CH340 chip is a compact, versatile, and cost-effective microcontroller development board designed for enthusiasts, students, makers, and engineers working on a variety of electronics and embedded system projects. Based on the widely popular ATmega328P microcontroller—the same chip used in the Uno—the Nano R3 delivers full IDE compatibility in a significantly smaller and breadboard-friendly form factor.

This particular model is equipped with the CH340G USB-to-Serial interface chip, providing reliable USB communication at a more affordable price compared to models that use the FTDI chip. Despite its budget-friendly nature, it retains the same core functionality and programming ease.

What sets this version apart is that it is unsoldered—header pins are included but not pre-attached—offering flexibility for users who want to customize their connections for compact setups or custom soldering needs. It’s perfect for prototyping, permanent installations, or soldering directly onto perf boards.

Additionally, this product does not include a USB cable, making it ideal for users who already have a Mini USB cable or are integrating the Nano into a permanent build where USB connectivity is not required after initial programming.
