■ 제품사양

Maximum Output Power = +13dBm Receiver Sensitivity = -148dBm Supported Bus Interfaces = SPI Supply Voltage = 3.3V
크기 = 16 x 16 x 1.8mm RFM9xW 433/868/915MHz ISM LoRa Transceivers, HopeRF. The RFM9xW Transceiver Modules feature the Semtech SX1272 transceiver chip which uses a variation of Chirp Spread Spectrum coding called LoRa?? to improve receiver sensitivity and hence achieve extended range. The module can also use OOK and FSK modulation schemes to maintain compatibility with other standards such as IEEE 802.15.4 and wMBUS. LoRa features increased interference immunity over conventional FSK providing an enhanced coexistence capability in crowded channels. Module Features.
