The Arduino Nano R3 Compatible Board with CH340 chip SOLDERED is a compact and efficient microcontroller board designed for embedded systems and prototyping where space is limited. It is based on the ATmega168 or ATmega328 microcontroller and offers similar functionality to larger boards like the arduino nano or UNO, but in a smaller footprint.
For Arduino based Projects used electronics component, due to its breadboard-friendly design and reliable performance. With 14 digital I/O pins and 8 analog inputs, it supports a wide range of sensors, actuators, and communication modules.
The Arduino Nano supports programming through a USB interface CH340, making it easy to upload code using the Arduino IDE. Its SMD version, often referred to as nano board (Soldered), ensures better stability.
StemVolt provides this Arduino Nano R3 Compatible Board for final-year engineering students working on IoT projects, robotics, and smart automation systems.
