Cheap Arduino Serial Driver

If you’re struggling to get a cheap Arduino clone to upload code using your IDE; the chances are that it’s not connecting via the COM port correctly. This maybe caused because your board uses a CH340G serial to usb chip, which Windows doesn’t recognise. Download the driver below or from the manufacturers website (in Chinese). Failing that, you could have bought a board without a bootloader. I’ll write a tutorial as soon as I get a board without one pre-installed.
