Description

The Chinese Uno R3 CH340 board differs from Italian Arduino UNO R3 boards in that it does not use the expensive FTDI USB-to-serial driver chip. Instead, it features the CH340 USB-to-serial converter chip which makes it low cost and 100% Arduino UNO R3 compatible board.

[!] Art of Circuits tests every Arduino Board before selling to customers. Buy Arduino Boards with peace of your mind.

Main Changes from the older version

Change the in-line package of ATMEGA328P to flat package.
