T-U2T USB to TTL UART converter, type-C Male to type-C Female, CH9102 - LILYGO® Q320


LILYGO T-U2T is the abbreviation of USB To TTL.
The original intention of this product design is that every time you design an ESP32 circuit board, you will find that the same circuit of USB To TTL appears on the schematic, especially when creating a small-sized circuit.

This circuit occupies a lot of space, and it also increases the cost, so we want to change it, Finally, we discovered that each product also has another feature that is the USB interface with TYPE-C.
So based on the characteristics of the male Type-c and female Type-C USB ports, we separately designed the CH9102 USB interface chip and automatic download circuit into the shape of a USB adapter.
