LilyGO T-QT C6 Mini Dev Board w/ ESP32-C6, 0.85-Inch Touch TFT

You can program the T-QT C6 using the Arduino IDE with the ESP32-C6 board package installed, Espressif's official ESP-IDF framework, or MicroPython. Connect the board via USB-C, select the correct COM port, and choose 'ESP32-C6 Dev Module' or a similar target in your development environment. The board's 4MB flash is sufficient for most applications. Example code for the GC9107 touch display is typically provided in the LilyGO GitHub repository to get started with graphics and touch input.

The onboard ETA4662 power management chip supports single-cell Li-ion or Li-Po batteries, typically with a voltage range of 3.7V nominal. The chip handles charging via the USB-C port and includes battery ADC detection for monitoring charge level. Connect your battery to the designated pads, ensuring correct polarity. The integrated breathing light LED provides a visual charging status indicator. For optimal performance, refer to the ETA4662 datasheet for specific input current limits and charging profiles supported by the IC.

The 0.85-inch TFT display uses the GC9107 driver chip and communicates with the ESP32-C6 via the SPI interface. You will need to include a compatible graphics library like TFT_eSPI or LovyanGFX in your Arduino or ESP-IDF project. Configure the library with the correct pin assignments for SPI_CLK, MOSI, and chip select (CS) as defined in the board's schematic. The capacitive touch layer is typically accessed via a separate I²C or SPI channel; check the provided example code for the specific touch controller initialization and reading touch coordinates.
