Description

Seeeduino LoRaWAN development board is a Long Range is an Arduino development board with Long Range protocol embeded, through which you can get started quickly to experience Long Range advantage in the field of IoT. 

Based on communication module RHF76-052AM, Seeeduino RHF76-052AM is compatible with Long Range Class A/C and supports a variety of communication frequencies. The 4 onboard standard grove connectors allow Seeeduino RHF76-052AM to connect with hundreds of grove sensors and actuators for Seeeduino conveniently, as a result, users are able to be more focus on the application itself without worrying about the compatibility issue between different modules.

In addition, Seeeduino LoRaWAN development board has embeded an integrated lithium battery management chip that allows the board to be charged by USB interface. In low consumption mold, a full charged lithium battery can power the board for several months. By using Seeeduino RHF76-052AM. You can build an IoT application very quickly.

We also offer another version with GPS module embeded, click here to find the Seeeduino RHF76-052AM W/GPS.

Note:

Please update the firmware when the first time to use it. Please always plug 3.7V Lipo battery in case USB power supply is not sufficient.

Getting Started

note

If this is your first time using Arduino, we highly recommend you to refer to Getting Started with Arduino

First you need to install the latest Arduino IDE, and ADD Seeeduino LoRa to your Arduino IDE.

Install the Driver (For Windows)

When the first time to insert the board, you should get a USB COM device name Seeeduino LoRaWAN that need to install a driver. Click on the below button to download driver for the board.

enter image description here

To make sure the driver was installed successful, open your Device Manager to see if Seeeduino LoRaWAN exists.

enter image description here

Now we can upload our first demo – Blink to Seeeduino LoRaWAN.

Open your Arduino IDE and click on File > Examples > 01.Basics > Blink to open the sketch or copy the blow code:

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin 13 as an output.
  pinMode(13, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);              // wait for a second
  digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);              // wait for a second
}

And Then,

  • Click on Tools > Board > Seeeduino LoRaWAN

If you can not find the Seeeduino LoRaWAN, please check How to Add Seeed boards to Arduino IDE

  • Click on Tools > Port to select a right port number. (Don’t choose COM1)

enter image description here

Then click on the Upload button on the left-top of Arduino IDE, seconds later the sketch was uploaded successful.
