LILYGO® TTGO T-U2T USB To TTL Automatic Downloader CH9102 Programmer Adapter Serial Development Board Open Source Module
LILYGO® T-U2T USB To TTL Automatic Downloader CH9102
- 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.
- We will start with new products (for example T-display e-paper version), there is no longer a duplicate USB To TTL circuit on the motherboard.
- And you only need a T-U2T to use the LILYGO motherboard. T-U2T is also an open-source product. Other products with USB To TTL circuits can also be designed to be compatible with T-U2T.
- This can not only save space on the circuit board but also save costs, especially in the current environment of a tight supply of chip wafers.
