  • TX Power: adjustable up to +14 dBm high efficiency PA.
  • FSK, GFSK, MSK, GMSK, LoRa and OOK modulation.
  • Low RX current of 10.3 mA, 200 nA register retention.
  • The shield comes with 1 x SMA 90 deg antenna connector, 1 x U.FL SMD antenna connector and 1 x single through hole for wire antenna.
  • 3 Grove connectors for sensors or other grove-compatible devices.
  • Interface via SPI with Arduino main board.
  • Option for OLED display.
  • Suitable for low power wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, etc.
  • Antenna Spec:
    • 2dBi gain
    • Impedance: 50 Ohm
    • VSWR: <=2.0
    • Terminated Terminal: SMA
    • Antenna Length: 10.9cm
    • Frequency: 915MHz

  • Packing List:

    • 1 x Shield-LoRa-RFM (915MHz)
    • 1 x 915Mhz SMA Antenna (50 Ohm)
    • 1 x U.FL to SMA Pigtail
  • Note: This is LoRa Radio shield, it does not contain LoRaWAN protocol, so the Arduino main board will require more program to store the LoRaWAN stack.
