Product Description
While this is a clone board, upgrade to the Official Arduino UNO R4 EK Minima — now ₹100 OFF! Use Coupon code UNO100 at checkout.
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.
Note: Actual product may vary in terms of design we will ship according to the stock availability
