This product is powered by EtherSIM, Particle's new globally available, self-optimizing SIM with no data plans or device fees. This model supported in Europe, Australia, and New Zealand.

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.

The B524 SoM is a new LTE-ready SoM to support global cellular IoT deployments around the World. The B524 is built on LTE-CAT 1, a globally available and mature LTE technology designed specifically for IoT devices with 50% the power consumption of 3G.

In addition to LTE-CAT 1, the B524 also comes equipped with Bluetooth 5.0 and full 2G/3G fallback, making it an ideal solution for navigating increasingly disruptive 2G/3G network sunset initiatives. 

The B524 features the same M.2 form factor as the rest of Particle’s B SoMs (like the B402) and comes with a full set of regulatory and industry certifications to dramatically accelerate time to market. The B524 has GA support for Europe today with support for additional international geographies coming later this year.
