Price: 24.00

The M5Stack Unit C6L is a LoRa-ready ESP32-C6 module with OLED display, RGB LED, buzzer, dual SMA antennas and Meshtastic support — ideal for private LoRa networks, remote monitoring and rapid prototyping.

The M5Stack Unit C6L is a compact, fully integrated LoRa communication unit built around the Stamp C6LoRa module, which uses the ESP32-C6 as its main controller and includes an SX1262 LoRa transceiver with an onboard RF switch. It supports an operating frequency range of 868–923 MHz.

The unit includes a 0.66" monochrome OLED display, a programmable RGB LED, a buzzer and a user button, giving it straightforward and intuitive interaction features. It can connect to the Meshtastic network or be used for secondary development, making it easy to deploy private LoRa networks for remote monitoring, outdoor exploration and emergency communication.

For wireless performance, the Unit C6L provides two SMA antenna interfaces—one for 2.4 GHz Wi-Fi 6 and one for LoRa—ensuring stable connectivity and flexibility. An onboard AW32901FCR over-voltage protection chip adds another layer of hardware stability.

With its HY2.0-4P expansion interface and LEGO-compatible mounting holes, users can easily add sensors or modules to quickly build out additional applications.
