STMicro has just launched a new development kit – STEVAL-FKI001V1 – that integrates two radios, one at 2.4 GHz for Bluetooth Low Energy (BLE), and another sub-GHz radio for LPWAN IoT standards such as Sigfox.
The devkit targets the development of IoT devices such as smart sensors, finders, and trackers for smart-home or smart-building scenarios, asset-tracking, energy-management, smart-farming and industrial monitoring, and control use cases.
STEVAL-FKI001V1 devkit key features & specifications:
