LilyGO T-Display-S3 is an ESP32-S3 WiFi and Bluetooth LE IoT development board with a 1.9-inch color LCD and support for LiPo batteries that follows the company’s T-QT ESP32-S3 board with a tiny 0.85-inch display introduced earlier this month.
The new board offers the same layout as the previous T-Display RP2040 or ES32 boards, but the 1.14-inch display has been replaced with a larger 1.9-inch display that covers most of the board, and thanks to the ESP32-S3 microcontroller, gains proper Bluetooth 5.0 support, as well as vector instructions for AI acceleration.
- Wireless MCU – Espressif Systems ESP32-S3R8 dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration, 512KB RAM, 8MB PSRAM, wireless connectivity
- Storage – 16MB flash
- Connectivity via ESP32-S3
- 2.4 GHz 802.11 b/g/n Wi-Fi 4 with 40 MHz bandwidth support
- Bluetooth Low Energy (BLE) 5.0 connectivity with long-range support, up to 2Mbps data rate.
- PCB antenna and external u.FL antenna support
- Display – 1.9-inch 320×170 IPS full-color LCD using the ST7789V 8-bit parallel display controller
- USB – 1x USB Type-C port for power and programming
- 2x 12-pin headers with up to 13x GPIO, 1x SPI, 10x ADC, SPI, UART, Touch interfaces, 5V, 3.3V, and GND
- 4-pin connector with 3.3V, GND, and 2x GPIOs/UART
- Misc – Boot, Reset, and user (IO14) buttons
- Power Supply
- 5V via USB Type-C port
- 2-pin 1.25mm pitch JST header for LiPo battery; voltage monitoring is possible through IO04 (but there may not be a charging circuit…)
- Dimensions – 62 x 26 x 10mm
The T-Display-S3 is also the second board from the company, after the T-QT V1.1, to feature an acrylic plate to protect the display and provide a sturdier design.
The TFT_eSPI library needs to modify some settings. It has been modified in the lib. Please use this library or add Micky_commit.patch to the local library.
The T-Display-S3 can be purchased on Aliexpress for $16.98 including shipping (but not VAT for Europeans).
