Description
CH340C programmer [extra pins exposed]
I needed an CH340C programmer with some extra pins exposed (RST / CST) and because I didn't find one, I decided to build one. :)
I wanted to keep it as small as possible, I chose to use 0603 resistors / capacitors/ LEDs. ME6211 is also a small footprint LDO. A small diode ensures reverse voltage protection.
Hope you guys find this useful !
