Disclaimer: This hardware SKU will be discontinued due to lack of availability of critical components driven by the ongoing global silicon shortage crisis. One we run out, we will not continue making more. For more details, visit our product discontinuation notification.

It is recommended that buyers of this impacted SKU migrate to our Supply Secure B404X SoM. This migration will require minimal hardware and firmware changes, as this new SKU is API, footprint, and electrically compatible with existing B SoM designs.

For more details, review our Supply Secure blog post.

The B SoM is our flagship IoT module for cellular-connected products. It runs on the Particle IoT Platform-as-a-Service — included for free for your first 100 devices — and includes a free global embedded SIM card and data plan. Optimized for mass production and scale, the B SoM is designed to be integrated directly into your circuit board design, plugging a M.2 NGFF connector on your board, allowing the module to be changed or upgraded easily.

The B404X SKU supports LTE CAT M1 connectivity and is appropriate for deployment in North America. Learn more about the B404X here.
