It supports 2.4 GHz Wi-Fi 6 and a documented 868–923 MHz LoRa range, with separate antennas included for the two radio bands. The integrated interface makes it suitable for mesh messaging, telemetry, alerts, remote sensors, and field experiments. Actual range and legal operating channels depend on region, antenna placement, terrain, interference, transmit settings, and local radio regulations.\u003c\/p\u003e\u003ch2\u003eMeshtastic and LoRa Networking with the M5Stack C6L Unit\u003c\/h2\u003e\u003ch3\u003eRun Meshtastic or Custom ESP32-C6 Firmware\u003c\/h3\u003e\u003cp\u003eThe ESP32-C6 provides RISC-V processing, 2.4 GHz Wi-Fi 6, and programmable control for Meshtastic-compatible operation or custom sensor, gateway, and messaging applications.\u003c\/p\u003e\u003ch3\u003eTransmit through the SX1262 Sub-GHz Radio\u003c\/h3\u003e\u003cp\u003eThe SX1262 transceiver supports long-range, low-data-rate communication across the documented 868–923 MHz hardware range.
