Ant2 USB-C LiPo Charger

Available on CrowdSupply

Ant2 is a tiny USB-C LiPo charger measuring just 16 x 9 mm in footprint. It is 30% smaller than the first Ant and is barely larger than the USB-C connector. It uses a popular Microchip MCP73831 in a DFN package, which minimizes the risk of thermal throttling.

Ant2 has half-cut mounting holes and despite the tiny size, it is still possible to conveniently mount it using regular M3 or M2.5 screws. The battery terminals are to be soldered directly to the board.
