Ant USB-C LiPo Charger
The USB-C has been around for quite a while, but there is still a lack of a miniature basic USB-C chargers for LiPo battery. I decided to make my own with as minimal footprint as possible, which resulted in being 13.5mm x 16mm.
A well known MCP73831T-2ATI/MC is used as a battery charger in DFN package, to minimize the risk of thermal throttling. A high quality USB-C connector is used from Amphenol (12401610E4#2A). The charging current is configured to 500mA. Battery wires should be soldered directly to the board by a user. Red and green LEDs indicate whether a battery is charging or is charged.
The mounting cutouts are designed for M2.5 or M3 size screws.
