This project is a USB-C daughterboard that provides with ESD protection and a standard 4-pin JST connector. Dimensions are approximately 42 x 11mm and has two M2 screw mounts. This daughterboard was heavily influenced by the C3 Unified Daughterboard project. While the C3 Unified Daughterboard is a great product, this daughterboard offers a different footprint and vertical JST connector.
