Connectivity Card MGM240P mPCIe¶
Connectivity Card MGM240P mPCIe¶
Release 1.2
Overview¶
Remote monitoring of critical infrastructure with edge computing¶
The MGM240P 5G Suite Connectivity Cards from CTHINGS.CO® are extension cards based on the Silicon Labs® MGM240P SoC. They are multi-protocol chips designed to empower IoT integrators to implement IEEE 802.15.4 connectivity like Bluetooth Low Energy, Bluetooth Mesh, Zigbee®, OpenThread® and other 2.4 GHz protocols. The extension card allows for full-fledged utilisation of the on-board 32-bit ARM® Cortex™-M33 CPU.
The product comes with full CE class-B and RED certification and can be used to quickly and reliably add 2.4 GHz protocol stack support to any existing device with a mini-PCIe slot without worrying about certification or radio performance. A full J-Trace connector is available on a programming jig for convenient firmware development.
CTHINGS.CO also provides support for Silabs Bootloader and EmberZNet Software Stack.
