    Particle’s solution for creating and managing IoT mesh networks

Particle Mesh gives every IoT device a local network

Traditional IoT devices that use Wi-Fi and cellular connectivity depend on the cloud to relay messages between devices. This works great when you’re making a standalone product – but sometimes you need more than that.

Particle Mesh development kits aren’t just connected to the Internet, they’re gateways to the Internet and create a local wireless mesh that other devices can join. These devices work together to ensure that messages get where they’re going, and power products that aren’t possible or economically feasible with Wi-Fi and cellular connectivity.

Take Vandelay Mining Company, who outfits their mines with wireless sensors and alarms to detect the presence of dangerous carbon monoxide gases. These alarms live deep underground beyond the range of either cellular towers or Wi-Fi routers.

With Particle Mesh, those sensors and alarms are connected directly over local wireless networks that ensure that the presence of poisonous gas is relayed quickly and reliably to each device on the network.

Particle Mesh gives every IoT device a local network to understand and connect with the world around it, ensuring products have the information they need to sound the alarm when it matters most.

IoT is ready for an upgrade. Particle Mesh is here to help.

Particle Mesh delivers more for less

Particle Mesh was designed specifically for IoT applications and built to solve some of the most common problems that affect widespread IoT deployments.

  • Low power

    to enable battery-powered endpoints

  • Low cost hardware

    to collect more sensor data for less

  • Reliable networks

    that protects your product from downtime

  • Local communication

    to ensure quick and reliable message delivery

Particle Mesh helps smart devices make intelligent decisions

Many IoT products today have the processing power of a smartphone but lack access to the environmental data and context they need to make the best decisions.

Particle Mesh hardware is inexpensive, battery-friendly, and resistant to failure, which makes it easy to add wireless sensors to your IoT product and ensure it has the information it needs to make intelligent choices.

What can you build with Particle Mesh?

  • Connected gardens

    that only water the plants that are thirsty

  • Swarm robotics

    that coordinate their movements in real-time

  • Cold chain transport

    that monitors each and every lab sample

  • Connected breweries

    that measure each step of the beer-making process

    The days of frustrating IoT device setup are over. Particle’s new bluetooth-based setup works with all our 3rd generation dev kits and makes life easier for developers, end customers, and everyone in between.

  • Local diagnostics over BLE

    Connect directly to your Particle Mesh devices over bluetooth to understand and appreciate the state of your devices in the field. Useful for quick debugging and viewing recent activity of your device.

  • Network management

    Creating a mesh network is one thing – effectively managing it is another. Particle’s web-based mesh network management tools make visualizing and administering mesh networks simple and secure.

Built on open standards and specifications

Particle Mesh is open source, reliable, and secure. If you’ve ever written digitalWrite() or heard of a REST API, you’ll feel right at home.

    Particle Mesh is compatible with Adafruit’s Feather form factor, providing access to 50+ FeatherWing hardware accessories.

  • Built on Thread

    Particle Mesh is built on Thread®, an open mesh networking standard released by the Thread Group.

  • CoAP over DTLS

    Particle devices use CoAP, a communications protocol designed for resource-constrained devices, secured with DTLS.

  • Open source hardware

    Particle Mesh development kits (schematic and board layout) are fully open source.

  • Open source Device OS

    Particle’s Device OS is open source. Submit a pull request at Github.

  • Open source developer tools

    Particle’s Desktop IDE and CLI are open source, hackable, and extensible.

Frequently Asked Questions

Product FAQs

  • What is Thread®?

    Thread® is an open mesh networking protocol released by the Thread Group. Particle Mesh uses OpenThread, an open source implementation of Thread® released by Nest, as the foundation of Particle Mesh, our mesh networking technology.

  • How many devices can each network support?

    Mesh networks are generally limited in size by RAM availability. The Nordic nRF52840 has a generous 256kb RAM and promises to support larger Thread® networks than were previously possible with other chipsets. However, until we’ve completed software development for the Argon, Boron, and Xenon, we won’t know for sure how many children each device can support. You can safely assume that each repeater and gateway will support at least 10-20 devices, making networks of 50+ devices possible.

  • Do I have to pay anything to use Particle Mesh hardware?

    Particle Mesh pricing builds on existing Wi-Fi and cellular Device Cloud pricing. All Particle customers get 10 free gateway upgrades to support prototyping and evaluation of Particle Mesh. After the first 10 upgrades, Particle will charge an additional monthly fee beyond baseline Device Cloud pricing for Argon and Boron devices acting as gateways within a Particle Mesh network. Adding mesh-only devices (Xenons) to your network and all local communications between mesh devices are free.

    With 10 free gateway upgrades you could build

    • One giant network of 100+ devices
    • Ten different networks of 10+ devices
    • Five different networks with redundant gateways (Ethernet + Cellular backup, for example)
  • Is Particle Mesh hardware compatible with my existing Particle accessories?

    Particle’s third generation hardware features a new hardware footprint that is compatible with Adafruit’s Feather specification, so our new dev kits are not compatible with Particle Classic accessories. We’ve created the Particle Classic Accessory Adapter, which we’re making available for a low cost ($5) to enable compatibility between new Particle Mesh hardware and existing Particle hardware accessories (like the Relay Shield and Asset Tracker).

  • Why do the photos of the Argon feature an Espressif's ESP8285 SIP, but the tech specs say ESP32-S0WD?

    Ah, very observant of you. We made a last minute call (between product photos and launch) to upgrade the Espressif Wi-Fi coprocessor to the newest variant of their ESP32 product family, the ESP32-S0WD. The ESP32-S0WD is a single core variant of the very popular ESP32, and is better supported than the ESP8285 with a fully open source developer SDK. Even better, we managed to incorporate that upgrade without any impact to the retail price point. How great is that?

    Our goal is to make it easy to review, edit, cancel, and add to your existing order all the way until delivery in July. You’ll find tools for editing and adding to your order on the order confirmation page for your preorder. If you run into a problem or need helping modifying your order details, send us a note at

Cellular FAQs

  • How much does cellular data cost?

    Every Boron comes with 3MB of data included as a part of its Device Cloud subscription. The first 3 months of Device Cloud are included for free with every new Boron (both LTE and 2G/3G) registered to your account. Pricing for cellular overages beyond 3MB are listed here.

  • Should I choose Boron LTE or Boron 2G/3G?

    If you live in the United States or Mexico, we recommend the Boron LTE which features cutting edge LTE CAT-M1 cellular technology for IoT devices. If you live outside of the US or Mexico, we recommend the Boron 2G/3G. We will add LTE support for international markets throughout 2018 and 2019 carriers complete commercial deployments for LTE M1 and NB1 around the world.

  • Why is LTE M1 only available in US and Mexico?

    Although many international carriers have deployed test networks for LTE M1/NB1 around the world, there are very few carriers who have completed deployments, are certifying devices, and supporting widespread commercial deployments on their network. As of today, Particle has partnered to provide initial LTE support in the US and Mexico via AT&T, and will be adding additional carriers to our MVNO throughout 2018 and 2019.
