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.
