Description

LILYGO T-LoRaC6 is a compact IoT development board based on the ESP32-C6-MINI-1 module, integrating 2.4GHz Wi-Fi 6, Bluetooth 5 (LE) and LoRa® long-range communication (SX1262 module, supporting 868/915MHz frequency bands), combining high performance with low power characteristics. The board features 4MB Flash, supports C/C++, MicroPython, Lua multi-language development, and is compatible with mainstream platforms such as Arduino-IDE, VS Code and ESP-IDF. It provides BOOT/reset buttons, custom LED and Type-C power interface for quick debugging and deployment. Its compact size (33x29mm) and multi-protocol integration capability (Wi-Fi/Bluetooth/LoRa) make it suitable for smart home control, industrial sensor networks, remote environmental monitoring and other scenarios. The 5V 500mA power supply design further simplifies mobile device integration, making it an ideal choice for low-power wide-area IoT applications.
