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.

    NOTE: NC should not be connected, and VCC output as supply voltage (USB power supply: 5V, Lithium power supply: 3.7V).

    FAQ

    • Hi!
      If I understand correctly, this module with antenna is the transmitter. Can the same module be used as receiver? So this would mean that I need to buy 2x this module to be able to work?

      Hi Menno,

      yes, you would need to get 2X of this module to use them as receiver and transmitter.
