LilyGo T-QT C6 Smart Ring Display Module with ESP32-C6

The LilyGo T-QT C6 is an innovative, portable mini-display module with an integrated ESP32-C6 microcontroller, Wi-Fi 6, and Bluetooth 5 LE. The compact, ring-shaped design allows real-time information to be displayed directly on the finger or back of the hand—ideal for applications where both hands need to be free, such as logistics, inventory management, food service systems, or manufacturing. The ESP32-C6, the 0.85-inch color TFT display, and all control electronics are integrated into the upper ring module. The base houses the built-in Li-Ion battery, which is charged via the USB-C port. The device can be programmed directly from the Arduino IDE, ESP-IDF, or PlatformIO and is ideally suited for compact, mobile IoT applications due to its modern architecture with a RISC-V processor, Wi-Fi 6, and Bluetooth 5 LE.
