• Note:You are responsible for determining if this frequency is allowed in your country

The LoRa/FSK Transceiver Module – 915MHz (RFM97CW) ideal for long-range wireless applications. With high integration, the RFM97CW simplifies the peripheral materials needed in system design.

The working voltage of RFM97CW is from 1.8 to 3.7V. When the sensitivity of – 138 dbm is reached, only 9.9 ma current is consumed, and the ultra-low power consumption receiving mode can further reduce the receiving power consumption of the chip.

The sensitivity up to – 138 dbm 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.
