LILYGO TTGO T-U2T USB to TTL Automatic Downloader CH9102 Programmer Adapter Serial Development Board Open Source Module

Product description Every time the ESP32 circuit board is designed, the same circuit as USB To TTL appears on the schematic, especially when designing small circuits. This circuit takes up a lot of space and also increases costs, so we wanted to change it. In the end, we found that each product also has another function, which is the USB interface with TYPE-C. Based on the characteristics of the C-type USB male port and the C-type USB female port, we designed the CH9102 USB interface chip and automatic download circuit into the shape of a USB adapter, respectively.

We will start with a new product (such as the T-pay electronic paper version), and there will no longer be duplicate USB to TTL circuits on the motherboard. And you only need one 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.
