Disclaimer: This hardware SKU will be discontinued due to lack of availability of critical components driven by the ongoing global silicon shortage crisis. For more details, visit our product discontinuation notification.

It is recommended that buyers of this impacted SKU migrate to our new Supply Secure Boron 404X. This migration will require minimal hardware and firmware changes, as this new SKU is API, footprint and electrically compatible with previous Boron designs.

For more details, review our Supply Secure blog post.

Buy this hardware and start building with Particle's Free Plan which includes support for up to 100 devices, cellular data, and fully-featured platform access with no time limit.

LTE-M cellular connectivity is supported in North America. Not in the region? Check out the B SoM LTE CAT1/3G/2G (Europe) with EtherSIM or Boron 2G/3G Global Starter Kit with EtherSIM.Continent compatibility is simplified and exceptions exist. Please be sure to check the full list of compatible countries for the location in which your product will be deployed.

The Boron LTE is a powerful LTE-M enabled development board that can act as a standalone cellular endpoint. It is based on the Nordic nRF52840 and has built-in battery charging circuitry so it’s easy to connect a Li-Po and deploy your local network in minutes.

The Boron LTE-M (NorAm) or BRN402 features the same form factor as the rest of the Particle’s Boron series modules and comes with a full set of regulatory and industry certifications to dramatically accelerate time to market. The BRN402 is certified only for use with the Taoglas Cellular Flex Antenna 2G/3G/LTE 5dBi.

Please note: Use of a different antenna with the above module may violate regulatory certifications and require additional certification. Refer to our antenna documentation for additional information regarding regulatory compliance and certification of Particle modules.

    *Antennas are not included with this item. Please purchase the ANT-FLXU-50 SKU separately.
