LILYGO T4-S3 board combines 2.41-inch AMOLED touchscreen display with ESP32-S3R8 microcontroller

LILYGO T4-S3 is yet another ESP32-S3 board with an integrated display, but the main difference here is the 2.41-inch AMOLED touchscreen display with brighter colors than typical TFT displays.

It’s actually not the first ESP32-S3 board with an AMOLED display from LILYGO as we previously covered the T-Track and T-Display-S3 AMOLED boards from the company, but the new T4-S3 has a larger 2.41-inch display with touchscreen function and an aspect ratio that may make it more suitable for a wider range of HMI applications.

The company claims the T4-S3 devkit supports Arduino, PlatformIO IDE, and MicroPython, but only provides Arduino/PlatformIO sample code on GitHub with the factory test code, a Qwicc GPS (UART) sample, a Qwiic HP303B I2S sensor sample, a touchpad demo, a TFT-eSPI sprite sample, and various LVGL samples. There are also other samples such as a LumenMeter, a PMU voltage detection sample, and a PMU interrupt sample that are designed for the T-Display-AMOLED-Lite board with a 1.47-inch AMOLED only. The GitHub repository also includes datasheets, mechanical drawings, firmware files, and PDF schematics.

LILYGO is selling the T4-S3 ESP32-S3 2.14 AMOLED board for $65.98 including shipping on Aliexpress.

Thats the same answer as before. He wants to know whats the vat amount. So it,s 75eur with 20% vat for me. Also usually prices in us is similar to prices in eu without vat because they pay their taxes later or smth. So ali price shown in aritcle is somewhat accurate for without vat price (60eur ali price converted from us, vs 62.5eur calculared from ali eu price).
