STMicroelectronics Dual Radio BLE and Sub-1GHz Development Kit WS2118-00 Bluetooth Development Board for Arduino,

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 Jordin), which embeds theBlueNRG-1 system-on-chip for Bluetooth® low energy functionality and the S2-LPtransceiver 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.
