Featuring T-Display-S3 with ESP32-S3 and 1.9 inch Color Display

T-Display-S3 is a development board that has ESP32-S3 as the main control chip. It features a color LCD screen that is 1.9 inches in size and two buttons that may be programmed. The connectivity is made possible by the use of the I8080 interface. It also maintains the same design and layout as the T-Display. The LCD Display Development Board has WIFI Bluetooth 5.0  and a wireless module with 170 x 320 resolution. The product page states that it is recommended to use a USB 2.0 cable (USB A-USB C cable) and that it is compatible with ST7789.

A new component has been introduced as part of the T-Display series. It comes equipped with the most up-to-date ESP32-S3 (which supports Wi-Fi 802.11, BLE 5, and BT mesh). The screen has also been widened from its previous measurement of 1.14 inches to its current measurement of 1.9 inches, and a plate made of acrylic has been added to fix it. This will be the second iteration of the LILYGO model display to incorporate a permanently attached acrylic plate. The T-Display series’ design is carried over into the overall aesthetic of the product.


  • The ESP32-S3R8 Dual-core LX7 microprocessor provides the necessary processing capability.
  • The programming platform consists of Arduino-ide as well as Micropython.
  • A 1.9-inch LCD diagonal Full-color TFT Display is an appealing characteristic of this product.
  • It offers a Resolution of 170 (H)RGB x320 (V) and Utilizes an 8-Bit Parallel Interface.
  • The ST7789V drive chip is the one that is used.
  • It has 16MB of Flash storage and 8MB of PSRAM, and it also has IO04 for detecting the voltage of the battery.
  • Moreover, there is an IO14 button, a boot button, and a reset button supplied.
  • Wireless connectivity is provided by Wi-Fi 802.11, Bluetooth Low Energy 5 (BLE 5), and BT mesh.
  • 3.3 volts is the working power supply.
  • It supports STEMMA QT/Qwiic and the JST-SH 1.0mm 4-PIN connectors.
  • The connector that is utilized is a JST-GH 1.25mm 2-PIN.
  • Dimension is 62mm x 26mm x 10mm.


The Arduino IDE, MicroPython, or the ESP-IDF framework are all listed as supported development environments for the board by LilyGO. However, the Github repository only provides fundamental instructions for getting started with the Arduino IDE and PlatformIO. T-Display-S3 can be purchased through LILYGO, Amazon, and Aliexpress.
