B SoM LTE-M (NorAm) with EtherSIM, Tray (B404X) [x50]
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. 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 B404 module supports LTE M1 connectivity.
