LILYGO T-QT C6

T-QT C6

Introduction

LILYGO T-QT C6 is a smart wearable development kit based on the ESP32-C6-MINI-1U microcontroller. It integrates a 0.85-inch TFT LCD display with a resolution of 128×128, a 6-axis sensor (LSM6DSL, supporting accelerometer and gyroscope functions), and a SGM41562 power management unit (PMU).

  • Key features include:

  • Built-in battery power supply,

  • Touch interaction,

  • Breathing light status indicator,

  • 4MB Flash storage,

  • QWIIC 4-PIN connector and I2C/SPI pins for hardware expansion.

It supports Wi-Fi and Bluetooth wireless communication and is suitable for applications such as motion tracking, embedded development, or portable interactive devices.

The product may adopt a ring-style extension dock design (T-QT-C6 Extended Finger Ring Dock), balancing low power consumption with high integration, making it ideal for prototyping and functional validation in fields like IoT and wearable devices.
