This PCB is an easy way to connect the SMD RFM to standard pins.
You can then place it on any breadboard or test PCB.
The order of the data lines are the same as that of the RFM.
All three RFM grounds are interconnected to the ground plane.
Regulate the voltage to 3.3v for the HopeRF RFM92/95 module.
The HopeRF RFM92/95 only works on 3.3 volt.
Higher voltage will damage your LoRa module!!
