By supporting concurrent communication over Bluetooth Low Energy (BLE) and Sub-1GHz wireless, the STMicroelectronics STEVAL-FKI001V1 dual-radio development kit gives unrivaled flexibility to envision, build and connect IoT devices like smart sensors, finders and trackers which can be configured, updated, remotely monitored and tracked using various network topologies, protocols and services.

The Kit 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 IoT Development Kit can readily be expanded through its Arduino™ Uno V3 connectors with the vast and comprehensive ST X-NUCLEO offering, including expansion boards with MEMS sensors, motor control, GNSS receivers or industrial input/output and power drivers.

The board is open source hardware and you’ll find software and hardware resources on the product page.
