Create a simple LoRa Node with a Wemos D1 and this interface PCB. This PCB is perfect for learning and experimenting with LoRa. Just add a Wemos D1 and a HopeRF RFM92 RFM95 LoRa module to the PCB. The PCB makes all the necessary connections to the LoRa module. And you are ready to go!
This PCB is an easy way to connect the SMD RFM to the Wemos D1.
The data lines are connected from the Wemos to 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!
This board is compatible with the Things4U the ESP_1ch_Gateway
Follow the instruction on the Github page to configure your Node/Gateway.
You must select the COMRESULT pinMode for this board. in configGway.h line 159 ~171
