PCB design by Mauro Alfieri and Marco Brianza
A LoRa shield for WeMos D1 mini boards
Made to experiment a LoRaWan radio node and single channel gateway.
based on the projects:
- WeMos-Lora https://github.com/hallard/WeMos-Lora
- Wemos shield template https://github.com/SuperHouse/D1MSHO
PCB tested ready for manufactoring:
- PCBWay https://www.pcbway.com/project/shareproject/LoRa_Node_1_3.html
- PCBs.io https://PCBs.io/share/4XRGg

To use the board as node use this version of the lmic LoRa library:
https://github.com/marcobrianza/arduino-lmic
It supports the LoraNode 1.3 pinout and fixes the radio power setting
Some practial examples with wrapping of the LMIC in more Arduinistic way are here: https://github.com/marcobrianza/LoraNode_Examples
To use it as gateway this repo:
https://github.com/marcobrianza/ESP-1ch-Gateway-v4.0/tree/LoraNode_1.3
The pinout is as the following table
- I2C pins are free to be used for sensors or GPIO (pull up resistor are optional on the bottom)
- D0 is free and can be connected to Reset with the "sleep" pad on the bottom of the board
- The 2 switches (normally opened) are shared with the serial port pins
- The LED is connecred in parallel with the Built in LED of Wemos
