The Uno R3 CH340G ATmega328p Development Board is an affordable alternative to the popular Uno R3 Arduino. It features the CH340 Micro-USB to Serial converter chip in place of the standard Atmega16U2 chip.
We have used numerous boards with the CH340 chip and found them to perform flawlessly. The CH340 chip is only utilized during programming or when using the serial output through the Micro-USB port. In regular operation, this board functions the same as the more expensive version without the CH340 chip.
Main changes from the older version:
1. 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
Why Choose Original Arduino Boards Over Clones?
Original Arduino boards offer superior quality, reliability, and long-term support, ensuring your projects
run smoothly and efficiently. Here’s a quick comparison:
How to use:
1. Download the IDE Arduino
Link: http://arduino.cc/en/Main/Software (Copy to open)
2. Download the Micro-USB chip driver
3. Plugin UNO development board, the driver will be installed automatically
4. Select the UNO from the die
5. Select the COM port
6. The best choice first, Arduino comes with routine procedures, burn into it.
