LoRa Transceiver Module (RFM95CW)

The RFM95CW LoRa Transceiver Module from Sparkfun is a high-performance, ultra-low-power device designed for a wide range of wireless applications. It operates on frequencies between 137 and 1020 MHz. With its high integration, the RFM95CW simplifies system design by reducing the need for peripheral materials. Its sensitivity reaches up to -148 dBm, optimizing the performance of your applications. The RFM95CW also supports a variety of functions, including Duty-Cycle operation mode, channel interception, high-precision RSSI, power-on reset, and noise output. This flexible design allows for unique and differentiated product designs. The module operates at a voltage of 1.8V to 3.7V and consumes a mere 9.9 mA current at peak sensitivity, making it an energy-efficient choice.

The RFM95CW LoRa Transceiver Module is ideal for applications that require long-range, low-power wireless communication. It can be used in a variety of scenarios, including remote sensing, home automation, and Internet of Things (IoT) devices. Its ultra-low-power receiving mode and minimal sleeping current make it a perfect choice for battery-powered devices.

Key features of the RFM95CW include a frequency range of 137 to 1020 MHz, LoRa modulation, data rate of 0.018 to 37.5 kbps, sensitivity of -123 dBm at 12KHz bandwidth and SF=12, and a voltage range of 1.8 to 3.7 V. It also has a receiving current of 12.5 mA at 125KHz bandwidth, supports ultra-low-power receiving mode, and has a 4-wire SPI interface. The sleeping current is 160 nA with Duty Cycle off and 600 nA with Duty Cycle on. Additionally, it supports full-automatic independent working mode.
