STEVAL-FKI001V1 Dual radio BLE and Sub-1GHz development kit for Sigfox™ and LPWAN protocols with BlueNRG-1 and S2-LP

The STEVAL-FKI001V1 development kit is a cost-effective tool to help you design solutions based on Sigfox™, Bluetooth® low energy and sub-1GHz technologies.

The kit features a fully programmable module WS2118 (by Jorjin), which embeds the BlueNRG-1 system-on-chip for Bluetooth® low energy functionality and the S2-LP transceiver for sub-1GHz functionality such as LPWAN protocols.

This development effectively combines Bluetooth low energy features with the connection capacity of Sigfox wide-area networks.

It includes examples and recommendations regarding the simultaneous use of the two protocols. Very low active RF and MCU current, and low-power mode current consumption provide excellent battery lifetime, allowing operation with coin cell batteries and energy-harvesting applications.

The STEVAL-FKI001V1 evaluation board uses the Arduino interface to help development, as it is compatible with ST Arduino shield boards featuring MEMS motion sensors, environmental sensors, and Time-of-Flight (ToF) ranging sensors.
