This is an automatic downloader adapter for USB to TTL, Motherboard Circuits ESP32 Serial Development Board Open Source Module.
(Currently only compatible with Windows, Mac systems of 10.15 and below)
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 a small-sized circuit.
This circuit occupies a lot of space, and also increases cost, so we wanted to change that. Also, we found that each product has another feature which is the USB interface with TYPE-C.
So based on the characteristics of the male Type- and female Type- USB ports, we separately
designed the CH9102 USB interface chip and automatic download circuit into the shape of an
USB adapter.
We will start with new products:
(for example: T-display epaper 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 supply environment of chip wafers.
