Product details

This is a T-U2T USB to TTL adapter from Lilygo. Every ESP32 board has the same USB to TTL circuitry, which takes up space on the circuit board and is only needed during programming. The purpose of this adapter is to incorporate the USB to TTL translation into a separate module with USB-C instead of on the board itself, allowing for the development of more compact ESP32 devices.

This adapter is used for all new ESP32 devices from Lilygo, such as the T5 E-Paper series. The adapter is an open-source product, meaning that other devices can also be developed with it.

Recommended accessory:
1m black USB 3.0 Type C cable
