Application schematic Interfacing a PIC

Micro Controller

The above schematic shows an easy interface to a PIC Microcontroller

This is the same application circuit that we used for range testing (please see our range test infor-

mation later in the document).

We also have application source code available for download on our website. This configures the RF

LoRa Module for maximum range.

Walk Test application

Also available is the source code used to carry out a simple range test.

In order to use this two application boards are required, one acts as a beacon transmitter, the oth-

er as the beacon receiver. The TX board will illuminate the GREEN LED when transmitting and the

Receiver will illuminate the RED LED when RECEIVING

The Transmitter board transmits an RF beacon every second (Green LED flashes to indicate trans-

mission).

This enables a one man range test, by placing either board in a fixed location and monitoring the bea-

con signals.
