Getting Started with the Photon RedBoard

The Photon RedBoard can be powered over either USB (using the included Micro-B Cable) or with a 4.5-15V barrel jack power supply (like either our 5V and 9V wall warts). To begin using your Photon RedBoard, plug it in!

USB plugged into Photon RedBoard

The red “POWER” LED should illuminate to indicate the Photon RedBoard is on. Also lighting up will be the RGB LED, which indicates which mode the Photon RedBoard is in.

RGB LED and Device Modes

The RGB LED on the Photon RedBoard identifies the connectivity status – or other state information – of the Photon P1 module. The color-to-mode mapping of the Photon RedBoard is described in detail in Particle’s Device Mode documentation. As a quick summary:

LED ColorLED activityDevice Mode
CyanBreathingConnected to WiFi and Particle Cloud
CyanBlinkingConnected to WiFi, Connecting to Particle Cloud
GreenBlinkingConnecting to WiFi
BlueBlinkingListening mode (waiting for WiFi info)
PinkBlinkingReceiving new application over-the-air
PinkBreathingConnected in safe mode
WhiteBreathingApplication running, WiFi off
Orange-YellowBlinkingDFU mode

The first time a Photon RedBoard is powered up, it should jump into listening mode – indicated by the blinking blue LED. That means it’s time to set up WiFi!

Configuring WiFi, Connecting to Your Particle Account

To use the Particle cloud – and their online IDE – you’ll need a Particle account. Head over to to sign up, if you haven’t already.

Create a Particle Account!

When you power on a Photon RedBoard for the first time, it should boot up into listening mode – indicated by a blinking, blue LED. It’ll remain in listening mode until configured with your WiFi network and password.

There are a handful of ways to configure a Photon’s WiFi credentials, including with the Particle smartphone app (iOS8+ or Android), or through a serial terminal. Unless you’re very comfortable with serial terminals – or just don’t have a smartphone nearby – we recommend using the app.

Windows users: To use the Photon in serial port mode, Windows users will need to install a driver. Follow Particle's "Installing the Particle Driver" guide for help installing the driver.

Both setup methods are described below, click one of the buttons to expand your section of interest:

Step 1: Download the Particle App

The Partice app is available for both iOS (8.0 and up) and Android phones: iPhone | Android.

Step 2: Follow the in-app directions to connect your Photon

1. After opening the app, press "Get Started", to arrive at the device list screen. Scroll to the bottom and select Setup a Photon...

Select "Setup a Photon..." to begin setting up your Photon RedBoard.

2. Verify that your Photon RedBoard's RGB LED is blinking blue, then select "READY" on the next screen.

3. Navigate to your phone's WiFi settings and find a network named something like Photon-9XYZ (with a random set of four characters as the suffix). Select it.

Your Phone should find a network name prefaced with "Photon-", connect to it.

4. Switch back to the Particle app. After a few seconds, the app should present you with a list of WiFi networks. Select the network you want to connect your Photon RedBoard to. On the next screen type in the network's password.

5. The penultimate screen will show the Photon RedBoard's progress as it connects to your WiFi network and the Particle cloud.

6. Finally, create a name for your Photon. You can go with Particle's (wonderfully random) suggestion, or one of your own.

If, for some reason or another, you can't use the Particle app to commision your Photon RedBoard, one alternative is using a Serial Terminal.

An alternative to this method – one that doesn't require serial terminal-ing – is Particle CLI. After installing particle CLI you can use the particle setup command to run through device setup. More information on that here.

1. Open a serial terminal program (check out our Serial Terminal Basics tutorial for suggestions) to your Photon's serial port. On Windows, the port should look something like COM#. On Mac, the port will be something like /dev/tty.usbmodem####.

2. Type i to get your Photon's Device ID. Copy it down – at least temporarily.

3. Type w to enter WiFi configuration. Then follow along with the prompts to enter you WiFi network's name and password.

Type 'i' to get your Photon's Device ID, then 'w' to configure its WiFi.

4. Go to the Particle Build IDE. Create an account if you haven't already, or log in.

5. Hop over to the "Devices" tab. Select Add New Device, and paste in your Photon RedBoard's Device ID.

Paste your Photon's Device ID into the Build IDE.

6. Name your new Photon RedBoard

7. Your Photon RedBoard will initially appear under the "Other" section, but after reloading the IDE, it should find its home under the "P1s" section.

Reset After Credentials are Entered: Once you have entered the WiFi credentials for your Photon RedBoard, you will likely need to hit the Reset button before your device will connect to the web. There is currently an error in the P1 module's firmware that does not automatically reboot the device once the credentials have been received. This should be fixed in a future release of the P1 firmware.
