LoRa/FSK Transceiver Module - 915MHz (RFM97CW)
Discontinued
The RFM97CW is a sub-GHz LoRa/FSK transceiver module operating at 915 MHz, based on the Semtech SX1276 IC. With receiver sensitivity down to −138 dBm (at BW = 125 kHz, SF = 12), it is well suited for long-range, low-power wireless applications such as IoT sensor networks, remote monitoring, and telemetry.
The module operates from 1.8–3.7 V with ultra-low sleep current as low as 160 nA, making it ideal for battery-powered deployments. Communication is via a 4-wire SPI interface, and the module supports fully automatic independent working mode and duty-cycle operation for power-efficient listening.
