Better known for its Linux and uCLinux-powered system-on-modules, emCraft has just launched the SOM-NRF9151 system-on-module powered by a Nordic Semi nRF9151 Arm Cortex-M33 SiP (System-in-Package) with LTE-M, NB-IoT, and DECT NR+ connectivity, and GNSS functionality.
The SoM also features a 16MB SPI flash, an nPMIC1300 for power management, a Nano SIM card slot, and a footprint for an eSIM. I/Os and power signals are exposed through two 50-pin board-to-board connectors, and the company provides a starter kit with a baseboard for evaluation.

emCraft provides a Zephyr BSP based on the Nordic SDK, pre-integrated with a customized Nordic Asset Tracker v2 application, and supporting FOTA (Firmware-Over-The-Air) updates and cloud connectivity through the Nordic cloud. You’ll find more details about the firmware and software on the documentation website, including links to the source code on GitHub.
The company also offers the SOM-NRF9151 Starter Kit with the nRF9151 module and a development baseboard for evaluation, prototype building, and early software development. The carrier board features a USB-C port for power and programming, an IMU sensor, a barometer and temperature sensor, several headers for I/Os, power, and configuration, a few LEDs and buttons, as well as a battery connector.
emCraft did not provide pricing and availability information for the nRF9151 system-on-module and starter kit, and you’d have to contact them to acquire a kit. Further information may be found on the product page.
