Description
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 B404X LTE SoM (B404XMEA). 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.
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 B SoM System-on-a-Module (SoM) can act as a standalone cellular endpoint. It is based on the Nordic nRF52840 micro-controller.
The B SoM is designed to be integrated into your circuit board design, plugging a M.2 NGFF connector on your board, allowing the module to be changed or upgraded easily.
The B402 module supports LTE M1 connectivity.
