Overview
The LILYGO T-QT C6 is a tiny ESP32-C6 development board — about the size of two thumbnails — offering WiFi 6 (802.11ax), BLE 5.0, and IEEE 802.15.4 (Zigbee 3.0 / Thread 1.3) in a compact package with a built-in 0.85-inch 128×128 TFT LCD touchscreen.
The ESP32-C6's 802.15.4 radio opens up direct Zigbee and Thread mesh networking without any additional hardware, enabling native integration with Matter smart home ecosystems. The ETA4662 battery charger IC provides LiPo charging and power path management, while a breathing LED adds visual feedback for status indication without consuming GPIO.
Despite its tiny footprint, the T-QT C6 exposes SPI, I2C, and UART headers for sensor expansion. The combination of WiFi 6 efficiency, Zigbee native support, and ultra-compact size makes it perfect for wireless sensor nodes, Matter bridge devices, and miniature display-equipped IoT gadgets.
