Unit C6L is a highly integrated LoRa communication device, built around the Stamp C6LoRa module featuring the ESP32-C6 as its core controller. It integrates the SX1262 LoRa transceiver and RF switch circuitry, supporting a wide 868 ~ 923 MHz frequency range for robust wireless communication.

This unit comes with a 0.66″ OLED monochrome display, a programmable RGB LED, a buzzer, and a user button offering intuitive human-machine interaction.

Whether you’re connecting to the Meshtastic network or building your own LoRa-based applications, Unit C6L enables rapid deployment of private networks perfect for remote monitoring, outdoor exploration, and emergency communication scenarios.

On the hardware side, it features dual SMA antenna ports for 2.4 GHz Wi-Fi 6 and LoRa, ensuring strong and scalable wireless performance. It also includes an AW32901FCR over-voltage protection chip for enhanced stability.

With its HY2.0-4P expansion interface and LEGO-compatible mounting holes, you can easily expand with sensors or modules to build your own smart applications.
