ADIY Uno R3 CH340K ATmega328p Development Board is the low-cost version of the popular Uno R3 Arduino. It is assembled with the CH340 USB to Serial converter chip, instead of using an Atmega16U2 chip. The only time the CH340 chip is used is during programming and when using the serial output of the USB port. During normal operation, this board is identical to the more expensive version without 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. Additional 3 rows of the holes for wiring. Changes to the DIP package of ATMEGA328P to flat package. CH340k replace ATmega16U2

How to use: Download the IDE Arduino Link: (Copy to open)  Download the USB chip driver Link: (Copy to open) Plug in UNO development board, the driver will be installed automatically Select the UNO from the die Select the COM port The best choice first, Arduino comes with routine procedures, burn into it.
