LoRa/FSK Transceiver Module, 915MHz, RFM97CW (COM-18084)

LoRa/FSK Transceiver Module, 915MHz, RFM97CW - Sparkfun COM-18084

RFM97CW Sub-GHz radio transceivers are ideal for long-range wireless applications. With high integration, the RFM97CW simplifies the peripheral materials needed in system design. The sensitivity up to - 138dbm that optimizes link performance for applications. In addition, the RFM97CW also supports the function of duty cycle operation mode, channel listening, high-precision RSSI, power-on reset, squelch output, etc., which makes the application design more flexible and realizes product differentiation design.
The working voltage of RFM97CW is from 1.8V to 3.7V. When the sensitivity of - 138dbm is reached, only a 9.9mA current is consumed, and the ultra-low power consumption receiving mode can further reduce the receiving power consumption of the chip.
