Hackoween badge

This has been made with a very hot needle in a very short timeframe.

PCB design is suboptimal.

It is based on the WCH CH32V003 MCU and draws between 11mA and 14mA at 5V.

To flash the badge, you need to have a WCH-LinkE programmer and the wlink CLI tool.

NOTE: The older WCH-Link (without E) does not work!
