LoRa Transceiver Module (RFM95CW)

RFM95CW is an ultra-low-power, high-performance LoRa transceiver for various frequency of 137-1020 MHz wireless applications. The high integration of RFM95C simplifies the peripheral materials needed in the system design. The sensitivity up to - 148 dBm which can optimize the link performance of applications. In addition, RFM95CW also supports Duty-Cycle operation mode, channel interception, high-precision RSSI, power-on reset, noise output and other more functions, which makes the application design more flexible thus to achieve product differentiation design. The working voltage of RFM95CW is 1.8V~3.7V. When the sensitivity is reaching -148 dBm, it only consumes 9.9 mA current. This ultra-low power mode can further reduce the power consumption of the chip.
