Quick start: Boron

The Particle Boron is a mesh and Bluetooth development kit designed for building connected projects and products. To set up the device you'll need an Android or iOS mobile phone and a connection to the internet.

The Boron Kit comes with the following things:

  • Boron development kit
  • Starter Project
    • One micro-USB cable
    • One mini breadboard
  • Electronic components
    • Two resistors (220 ohm)
    • One light-emitting diode (LED)
    • One phototransistor

1. Set up your Boron

For a short (~4 min) overview of what the Boron setup process looks like, watch the video below.

Once you're ready to proceed, use the online setup application to configure your new Boron. The process includes the following.

  • Registration of your device with your Particle account
  • Connection of your device to the Particle Device Cloud
  • Particle Mesh network configuration

Once you've completed the setup you will be able to program your device and send over-the-air (OTA) updates to it.

To begin setting up your Boron, click the button below and follow the onscreen instructions. When you've completed set up, continue to Step #2.

1.) If you have already set up your Boron, skip to Step #2.

2.) During set up you may skip setting up a Particle Mesh network and use the Boron in a standalone mode.

2. Open the Web IDE

To program your Boron, open a new browser tab and go to the Web IDE.


The Web IDE is one of the ways you can write, compile, and deploy code to your Particle devices.

If you're looking for a more traditional embedded development experience, be sure to learn about [Particle Workbench], a full toolchain integration with Microsoft Visual Studio Code.

The code is heavily commented to help you understand the general structure of the sketch: the first part of the code declares two variables, the setup() function configures two pins as outputs, and finally the loop() which turns the onboard LED on, then off, then loops continuously.

4. Target your device

The Web IDE can be used with multiple devices. As such, when you go to compile source code, it's a good idea to verify that the board you

Before you compile the source code and flash your device with its binary output, make sure that the correct Particle device is selected.


If you don't see your Boron listed, click on the device name. A sidebar will appear on the left with a list of all of your devices. Click on start to the left of the Boron you wish to deploy code to.

5. Compile your code & flash

Click the lightning bolt icon on the top left of your screen to flash your code to your device.

As soon as you click, the Particle Device cloud will compile the program source code to a binary file and send it over-the-air (OTA) to your Argon.


You'll often see words like flashing and deploying used interchangeably.
