Description
The Uno R3 CH340G ATmega328p Development Board is a popular and versatile microcontroller board ideal for beginners and experienced makers alike. It’s based on the ATmega328P microcontroller and features a CH340G USB interface chip, providing a cost-effective and reliable way to connect to your computer. This board is compatible with the Arduino IDE, making it easy to program and use with a wide range of projects. It offers digital and analog input/output pins, allowing you to interface with various sensors, actuators, and other electronic components. The board also includes a Micro-USB connector for easy programming and power. Whether you’re building robots, home automation systems, interactive art installations, or learning about embedded systems, the Uno R3 is a great starting point.
The Uno R3 CH340G ATmega328p Development Board is the low-cost version of the popular Uno R3 Arduino. It is assembled with the CH340 Micro-USB to Serial converter chip, instead of using an Atmega16U2 chip.
We have used plenty of these low-cost Arduino boards with CH340 chips, and have found them to work perfectly. The only time the CH340 chip is used is during programming and when using the serial output of the Micro-USB port. During normal operation, this board is identical to the more expensive version without the CH340 chip.
Main changes from the older version:
- Two rows of holes for the pins (Male and Female). So it can be connected with normal Female Jumpers.
2. Additional 3 rows of the holes for wiring.
3. Changes to the DIP package of ATMEGA328P to flat package.
4. CH340G replace ATmega16U2
