Hardware overview

Finding the right Particle hardware for your project

  • If you want an off-the-shelf, complete device with little or no hardware design required, see off-the-shelf complete below.
  • One way to start finding the right device is whether you're a hobbyist, prototyping, or producing a product. To start there, see prototype or production below.
  • Another way to start is by deciding on cellular or Wi-Fi first.

Prototype or production

Prototyping

For easy prototyping, devices with pins on the bottom can easily be installed in a solderless breadboard.

Breadboard

The Photon 2, Argon, and Boron use the Adafruit Feather form-factory so easily add accessories like sensors and displays, with no wiring required.

Boron GPS FeatherWing

Even though these devices are ideal for prototyping, you can also scale with the Photon 2 and Boron BRN404X. For example, you may mount the device in a socket in your own custom circuit board when you're ready to scale, instead of using solderless breadboards or off-the-shelf Feather adapters.

There are also evaluation kits for the B Series SoM, Tracker SoM, and E Series modules that can be used for prototyping with those modules.

If you're not sure whether you want cellular or Wi-Fi, see Cellular or Wi-Fi below.

  • The Argon has been deprecated and will be replaced by the Photon 2. For the differences, see the Argon to Photon 2 migration guide.
  • The Boron 2G/3G (BRN314KIT) has been deprecated (along with all other 2G/3G SKUs) as the u-blox SARA-U201 cellular modem module on it is end-of-life.
  • The Boron LTE Cat M1 (BRN404KIT or BRN404X) is the recommended model for the United States, Canada, and Mexico.
  • Can be powered by USB, rechargeable LiPo battery, or an external power supply.
  • All Boron devices include a built-in Particle SIM card (free for use up to certain limits, no credit card required).
  • Starter kits include a mini-breadboard, USB cable, two resistors (220 ohm), one red LED, and one photodiode.
  • ARG-STRTKT includes a variety of Grove sensors and a display.
  • A battery is included with the Boron 2G/3G (BRN314) as the cellular modem uses more power for brief periods of time than a standard laptop USB port will supply.

There are numerous ways to expand Gen 3 devices:

  • Adafruit FeatherWing compatible modules can add things like displays, sensors, relays, with no wiring necessary.
  • SparkFun Qwiic and Adafruit Stemma-QT modules provide a way to add features connected by a small I2C cable. Multiple modules can be chained together, as well.
    • Environment sensors (pressure, temperature, humidity) like the BME280
    • Buttons and indicator buttons
    • Load cell adapter (weight sensor)
    • Distance and proximity sensors
    • Thermocouple adapters
    • Relays
    • Keypads
    • Small displays
  • Grove sensors and displays connect to digital, analog, I2C, and serial devices with a simple 4-pin cable.

Its also possible to prototype with these easy to use modules, then include the same functionality on a custom board later. The Adafruit and SparkFun designs are all open-source and include hardware design files for EagleCAD.

The Beyond Prototyping Tutorial shows examples of how you can move from prototyping to custom circuit boards, with example designs.

For more information about the Boron, see Cellular below.

For more information about the Photon 2 and Argon, see Wi-Fi below.

Production

When producing at scale, you may prefer to use devices that you reflow solder to your own base board (E Series, P2, P1, and Tracker SoM) or securely mount in a M.2 socket (B Series SoM).

If you're not sure whether you want cellular or Wi-Fi, see Cellular or Wi-Fi below.

While you can use prototyping devices at scale, if you will be needing devices over a long period of time, production devices will generally be maintained for a longer period of time. For example, the Electron (prototyping) was discontinued before the E Series (production), even though both have similar hardware.

The software for prototyping and production devices is similar. It's often possible to use a single code base to work with both types of modules. And, in many cases, across both Gen 2 and Gen 3 devices, or across both cellular and Wi-Fi devices.

B Series SoM (Gen 3 Cellular)

B Series

The B Series SoM (system-on-a-module) is similar to the Boron in that it is a 3rd-generation cellular device. It plugs into an M.2 NGFF connector on your custom circuit board and is intended for mass production use.

Many of the extra features on the Boron have been omitted from the SoM, so you can implement a custom solution as necessary. For example, rather than duplicating the buttons and status LED on the SoM, you can put them on an external control panel for your product, or omit them entirely.

Additionally, the extra width vs. the Boron (Adafruit Feather) form-factor makes it possible to include a LTE Cat 1 with 2G/3G fallback cellular modem, such as the Quectel EG91-E on the B524. This modem is too wide to fit on a Boron.

1The PMIC (power management IC) and fuel gauge are used with battery-powered applications. They're omitted from the SoM as they are not needed for externally powered solutions (grid or automotive power, for example). Additionally, you may want to use different models if you are making a solar-powered device, or using a different battery technology or multiple battery pack.

2The built-in Particle SIM card is free for use up to certain limits, no credit card required.

For more information about the B Series SoM, see Cellular - B Series SoM below.

Tracker SoM (Gen 3 Cellular)

SoM

The Asset Tracker SoM is a castellated SoM designed to be used with the Tracker One or reflow soldered to your own base board. It has features including:

  • Gen 3 hardware platform (nRF52840 MCU)
  • Quectel cellular modem
  • GNSS (GPS)
  • IMU (accelerometer)
  • Real-time clock
  • Built-in Particle SIM card (free for use up to certain limits, no credit card required).
  • PMIC and fuel gauge chips (charger and battery level sensor)
  • Hardware watchdog

For more information about the Tracker SoM, see Cellular - Tracker SoM below.

E Series (Gen 2 Cellular)

E Series

The E Series modules are generally 2nd-generation cellular device that is reflow soldered to your custom base board. As the software is fully compatible between the Electron and E Series, you can easily move from prototyping to mass production with the same software.

  • The E310, E313, and E314 are deprecated due to the end-of-life of the u-blox SARA-U201 cellular modem module.
  • The E402 and E404 will be replaced by the E404X. Note, however, that this is not a drop-in replacement as there are significant differences between these two modules. See the E404X migration guide for more information.
  • New designs should use the B Series M.2 SoM instead of the E Series form-factor.

P2 (Wi-Fi)

The P2 module is a Wi-Fi module that you reflow solder to your own custom base board. It's smaller and less expensive than the Argon.

Both the P1 and Argon are deprecated, as designs should either use the Photon 2 (which includes the P2 module on it), or directly use the P2.

The P1 module has been deprecated and is replaced by the P2 module, which is mostly pin-compatible. See the P2 from P1 migration guide for more information.

For more information about the Wi-Fi modules, see Wi-Fi - P1 below.

Cellular or Wi-Fi

A common question to start with is how you want to connect to the Internet.

Cellular

While cellular hardware is initially more expensive, the total cost to onboard a customer with cellular may be lower due to the other expenses involved in Wi-Fi deployments:

  • No requirement to provide a method of configuring Wi-Fi credentials, such as a custom mobile app
  • No dependence on the customer's Wi-Fi network, which may be inconsistent
  • No troubleshooting site-specific Wi-Fi configuration issues

B Series SoM (Production Gen 3 Cellular)

Both Cellular and Wi-Fi

There are no Particle devices that include both cellular and Wi-Fi connectivity in a single device. While the Tracker SoM and Tracker One include cellular and Wi-Fi, the Tracker Wi-Fi can only be used for geolocation and cannot be used to connect to the Internet.

If you want an option of cellular or Wi-Fi in your product, you'll need two or three different SKUs, however the best choice is:

  • Wi-Fi: Photon 2, Argon
  • Cellular: Boron LTE (North America), Boron 2G/3G (Global except NORAM)

These modules are pin-compatible in the Feather form-factor, so you can make two versions of your hardware, one cellular and one Wi-Fi, which you can use depending on local connectivity, for example.

The Photon 2, Argon, Boron are compatible with the Ethernet FeatherWing.

With the B Series SoM you can implement Ethernet on your custom base board fairly simply using the WIZnet W5500 chipset. The B Series Eval Board includes this circuitry.

With the P2 module, you can implement Ethernet on your custom base board fairly simply using the WIZnet W5500 chipset. There is no evaluation board for this combination, but the circuitry is straightforward and conceptually the same as the B Series, though the specific pins are different.

You can also include Ethernet functionality on your Tracker SoM base board, but this is an unusual configuration and the Tracker SoM Eval board does not include Ethernet.

It is not possible to use Ethernet with Gen 2 devices (Photon, P1, Electron, or E Series).

Ethernet is only intended for use as a method of connecting to the Internet. It is not intended to connect to isolated Ethernet segments such as Ethernet control networks, and relay information over cellular, for example. See the AN037 Ethernet application note for more information.

The following pins are used by Ethernet. These cannot be reconfigured.
