FireBeetle SX1276 LoRa 868MHz Wireless Transmission Module

SKU: TEL0125

DFRobot FireBeetle IoT series are low-power controllers for IoT development, including Boards, Covers, and Accessories. The FireBeetle LoRa 868MHz module uses the SX127x chip with built-in PA, is Arduino-compatible, supports long-range communication, FSK (max 300Kbps) and LoRa (max 37.5Kbps) modulation, and has a low-power mode of <0.2uA. It’s suitable for home automation, health monitoring, and wearables. Note: Maintain consistent wireless parameters in the same network to avoid communication issues.

    Pinout

    FireBeetle Covers-LoRa Radio 868MHz mainly communicates via SPI interface(MISO, MOSI, SCK, CS, RESET), and couples these control ports to the SPI interfece(MISO, MOSI, SCK) on the FireBettle mainboard. CS(chip-select) and RESET are connected to D2, D3, D4, D5 by DuPont wires.
