Tutorial: How to Use ESP32 LoRa Board

This board allows you to send and receive data over long distances using the 433MHz frequency, ideal for IoT projects. Suitable for beginners and intermediate users.

What you need

• Arduino IDE
• USB cable
• LoRa antenna
• Computer with Windows 10 or macOS

Steps

1. 1. Download and install the Arduino IDE.
2. 2. Connect the board to the computer via USB cable.
3. 3. Check the datasheet for the firmware version.
4. 4. Load the LoRa example code in Arduino IDE.
5. 5. Connect the LoRa antenna to the board.
6. 6. Configure the LoRa parameters (frequency, bitrate) in the code.
7. 7. Try to send a message from one module to another.
8. 8. Verify the reception of the message.

Example code

```
#include <LoRa.h>

void setup() {
  Serial.begin(9600);
  LoRa.setPins(4, 5, 6); // Setta i pin usati
  if (LoRa.begin(433E3) != LORA_OK) {
    Serial.println("Error initializing LoRa");
    while (1);
  }
}

void loop() {
  Serial.println("Sending message...n");
  LoRa.send("Hello World");
  delay(5000);
}
```
