Hello,
I bought ARDUINO UNO R3 with CH340 cip from Asian market...
The installation of USB 340 appear correct on Sytem.
The ARDUINO IDE 1.8.1 seems to be correct installed. When RESET board LED L blinking and after solid RED.
It is no way to Upload Sketch or Burn Boot-loader !
Can somebody suggest behaviours of ARDUINO UNO R3 ?
Please supply the following information.
OS and version ?
Type of USB ports being used ?
What COM port is being used ?
You're going to need to use a driver for this board. Google "CH430 driver for Windows 8" (or whatever operating system your computer is using), and download a driver.
Issue sorted... self installation of CH340 on Windows 7 Pro; Installation didn't started when plug Arduino R3 !
