Frequently Asked Questions

How do I program the LilyGO T-Display-S3 board?

You can program it using the Arduino IDE with the ESP32 board package, Espressif's ESP-IDF framework, or MicroPython. In Arduino, select 'ESP32S3 Dev Module' as the board, set the PSRAM to 'OPI PSRAM', and use the TFT_eSPI or LovyanGFX library for the display. Ensure the correct USB driver (CP210x or CH340) is installed for serial communication.

What is the power supply requirement and how do I connect a battery?

The board requires a 3.3V DC power supply. You can power it via the USB-C port or connect a single-cell LiPo battery (3.7V nominal) to the onboard JST-GH 1.25mm 2-pin connector. The board includes a charging circuit, and you can monitor battery voltage via the IO04 pin in your firmware for accurate battery level readings.

Which libraries are recommended for driving the touch display?

For Arduino, use the TFT_eSPI library with a custom User_Setup.h file configured for the ST7789V driver and 170x320 resolution. Alternatively, the LovyanGFX library offers high performance. For touch functionality, the built-in FT6236 or CST816 capacitive touch controller is supported by corresponding Arduino libraries. In MicroPython, use the lv_micropython library for a full GUI framework.

Can I connect external I2C sensors to this board?

Yes, the board features a STEMMA QT / Qwiic-compatible JST-SH 1.0mm 4-pin port (I2C) for daisy-chaining compatible sensors without soldering. You can also use the broken-out GPIO pins via the provided PH2.54 headers to connect standard I2C, SPI, or digital sensors. Remember to use 3.3V logic level for all peripherals.

Package Includes

  • 1 x LilyGO T-Display-S3 ESP32 1.9-inch Touch Board (non-solder version)
  • 2 x PH2.54 Pin Headers (1x12P)
  • 1 x JST 1.25mm 2P Connector
