Hello friends, I hope you are doing well. In today's tutorial, I am going to share our SX1262 LoRa Proteus Library . The SX1262 is the newer LoRa chip from Semtech with an output power of up to +22 dBm. With this library, we can place two SX1262 modules in one Proteus design, connect each of them to an Arduino Mega 2560 and send messages from one board to the other at 868 MHz. The Arduino code uses the popular RadioLib library, and a row of distance buttons lets us test a link of up to 20 km. We will start with the basics of the SX1262 and see how it differs from the older LoRa chips. Then we will install the library files, wire the circuit and run the supplied simulation. The main part of this tutorial is the control panel of the module. We will read every line of it and test how the dist ...
Hello friends, I hope you are doing well. In today's tutorial, I am going to share our SX1278 LoRa Proteus Library . It adds the popular Ai-Thinker Ra-02 module to Proteus. We can place two of these modules in one design, connect each of them to an Arduino Uno and send messages from one board to the other at 433 MHz. The receiver prints every message with its signal strength and its signal-to-noise ratio, and a row of distance buttons moves the two radios up to 20 km apart. First, we will look at the SX1278 chip, the Ra-02 board and the basics of LoRa. Then we will install the library files, wire the circuit and run the supplied two-Arduino simulation. The main part of this tutorial is the control panel of the module. We will read every line of it and test how the distance, the spreading f ...
