From the project

Open hardware extension board for Lichee-Jack with battery, Ethernet, and LED integration.

This sub-directory contains the USB 2.0 hub + UART converter board designed specifically for the Lichee-Jack project. It is intended to simplify development, debugging, and flashing by combining USB OTG, UART console, and power control into a single compact board.

The LicheeRV Nano features a USB 2.0 Type-C OTG port implemented directly by the SoC PHY. This design is slightly different from a typical USB 2.0 Type-C implementation:
