CH340G is 5V powered, not 3.3V

CH340G is 5V powered and thus pushing 5V level (through R12 ~4.3V) into ESP12 on RXD0 instead of 3.3V level.

This would explain why my 0.9 boards are unstable and difficult to flash.

Argh, lovely...

Where is the software for these drivers? The one on here drives me nuts as it keeps disconnecting and connecting.
