RFM69HW LoRa Module
The RFM69HW module is available in 3 different operating frequencies, 433MHZ, 868MHz, and 615Mhz. While buying the module we should consider the license-free ISM (Industry Scientific and Medical) frequency band in our respective countries. The FRM69 is highly optimized for low power and offers a very large coverage. It can output upto 100mW output power. It is highly sensitive up to -120dBm at 1.2kbps.

How To Use RFM69HW Module?
The RFM69HW module uses the SPI communication protocol for interfacing. So, it can be used with any microcontroller with SPI bus. Like most of the RF module, it is necessary to connect an antenna to the module, otherwise the PA section of the module can be permanently damaged. And the power supply and communication bus voltage should be 3.3V and it should never exceed 3.6V to avoid damaging the module. A simple connection diagram for the module is given below.
