LILYGO T-QT V1.1 a tiny board with an ESP32 and a 0.85-inch color display

LILYGO T-QT V1.1 board changes that and combines the dual-core WiFi 4 and Bluetooth LE 5.0 AI microcontroller with a 0.85-inch color display.

The board also happens to be rather small and comes in at a tiny 33 x 18 mm form factor, and also offers some I/O via headers and a 4-pin connector, and can be powered via its USB Type-C port or a battery

  • Storage – 8MB 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.
    • On board and external antenna support
  • Display – 0.85-inch 128×128 IPS LCD with 262K colors based on GC9107 SPI display controller
  • USB – 1x USB Type-C port for power and programming
  • Expansion
    • 2x 7-pin headers with up to 11x GPIO, FSPI (fast SPI), ADC,  Sub SPI bus, 5V, 3.3V, and GND
    • 4-pin connector with 3.3V, GND, and 2x GPIOs
  • Misc – Reset button, 2x user buttons
  • Power Supply
    • 5V via USB port
    • 2-pin header (unpopulated) for battery; voltage monitoring is possible through IO04, but there’s no charging circuit

Development

Arduino:

  • Click “File” in the upper left corner -> Preferences -> Additional Development >Board Manager URL -> Enter the URL in the input box. (ESP32S3 is a new chip, and the SDK version needs to be version 2.0.3 or above) https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
  • Click OK and the software will be installed by itself. After installation, restart the Arduino IDE software.

PlatformIO:

  • PlatformIO plug-in installation: Click on the extension on the left column -> search platformIO -> install the first plug-in
  • Click Platforms -> Embedded -> search Espressif 32 in the input box -> select the corresponding firmware installation

Purchase

The LILYGO T-QT V1.1 costs about £11 from Aliexpress. The T-QT Pro costs around £13.70
