Particle Introduces New Hardware, Adds Mesh Support
Wednesday, 14 February 2018 13:31

Particle, makers of the WiFi and Cellular IoT modules everyone loves, is introducing their third generation of hardware. The Particle Argon, Boron, and Xenon are Particle’s latest offering in the world of IoT dev boards, and this time they’re adding something amazing: mesh networking.

New Particle boards named Argon, Boron, and XenonThe three new boards are all built around the Nordic nRF52840 SoC and include an ARM Cortex-M4F with 1MB of Flash and 256k of RAM. This chip supports Bluetooth 5 and NFC. Breaking the new lineup down further, the Argon adds WiFi with an ESP32 from Espressif, the Boron brings LTE to the table with a ublox SARA-U260 module, and the Xenon ditches WiFi and Cellular, relying only on Bluetooth, but still retaining mesh networking. This segmentation makes sense; Particle wants you to buy a ton of the Xenon modules to build out your network, and use either the Argon or Boron module to connect to the outside world.

The form factor of the boards conforms to Adafruit Feather standard, a standard that’s good enough, and much better than gigantic Arduino shields with offset pins.

Of particular interest is the support for mesh networks. For IoT solutions (whatever they may be), mesh networking is nearly a necessity if you have a sufficient number of nodes or are covering a large enough area. The technology going into this mesh networking is called Particle Mesh, and is built on OpenThread. While it’s a little early to see Particle’s mesh networking in action, we’re really looking forward to a real-world implementation.

Preorder pricing for these boards sets the Argon module at $15, the Boron at $29, and the Xenon at $9. Shipping is due in July.
