Overview

The STEVAL-FKI868V2 is an evaluation board based on the S2-LP sub-1GHz transceiver, designed for high-performance wireless applications in the 868 MHz band. It provides a complete RF platform to evaluate the S2-LP low-power features and integrated protocol engine for reliable data transmission.

Why Choose This Part

The S2-LP transceiver offers exceptional power efficiency with a receive current of 6.7 mA and a transmit current of 10 mA at +10 dBm. The integrated protocol engine simplifies development by handling automatic acknowledgement, retransmission, and timeout tasks autonomously.

Applications

Sigfox Connectivity
Designing ultra-narrowband IoT nodes for long-range communication on the Sigfox network.
Wireless M-Bus
Implementing smart metering solutions for gas, water, and heat meters using the 868 MHz ISM band.
Smart Agriculture
Deploying remote sensor nodes for soil moisture and environmental monitoring with minimal power consumption.
Home Automation
Building sub-GHz mesh networks for lighting control and security systems that require superior wall penetration.
