Disclaimer: This hardware SKU will be discontinued due to lack of availability of critical components driven by the ongoing global silicon shortage crisis, with a last request to buy date on June 30, 2022. For more details, visit our .
It is recommended that buyers of this impacted SKU migrate to our new Supply Secure Boron 404X HDK. This migration will require minimal hardware and firmware changes, as this new SKU is API, footprint, and electrically compatible with previous Boron designs.
This product is powered by EtherSIM, Particle's new globally available, self-optimizing SIM with no data plans or device fees.
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 CAT-M1 cellular connectivity is supported in North America. Not in the region? Check out the B Series LTE CAT1/3G/2G (Europe) with EtherSIM or Boron 2G/3G Global Starter Kit with EtherSIM. See the cellular FAQ for details. 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 CAT-M1 enabled development kit that can act as a standalone cellular endpoint. Boron LTE 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 CAT-M1 (NorAm) Starter Kit with EtherSIM or BRN404KIT 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 BRN404KIT 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.
