The T-Display S3 board with ESP32-S3 WiSoC and a 1.9-inch color LCD

T-Display-S3-pinout

This is a new addition to the T-Display series from Lilygo, the board comes with an expanded screen of 1.9-inch, previous boards had a 1.14″ display screen.

Another nice touch is the addition of an acrylic support plate, I’ve seen a few other similar boards were the display was loose. This does make it potentially tricky to solder headers to the board as this plate is fitted above the header.

The T-Display-S3  module can support dual power supplies as it has a USB type-C connector through which power can be provided from a 5V external power adapter, and a 2-pin JST GH 1.25mm header through which a Li-Po battery can be connected

The board use the latest ESP32-S3 and Bluetooth 5.0.
