Setting up LoRa SX1278:

The LoRa SX1278 works with SPI communication protocol so it can be used with any microcontroller that supports SPI. It is mandatory to use an Ariel (antenna) along with the module else it might damage the module permanently. The module should be powered only with 3.3V and the SPI line can be connected to uP/uC as shown in the image below.

Lora circuit diagram

To communicate with the module some standard libraries are also available for Arduino like LoRa by Sandeep and other platforms. The module comes in a surface mount style package hence care should be taken while soldering. It is also a common practice to solder wires and pins with the module to use it as through hole module.

 

Applications:

  • IoT Applications
  • Home and Building Automation
  • Long range communication
  • Mesh or star topology networks
  • Industrial monitoring and control
