Image of STMicroelectronics' S2-LPQTR RF Transceiver STMicroelectronics' S2-LP transceiver is designed for superior RF performance and unparalleled energy efficiency, extending battery life from months to more than 10 years. The embedded radio guarantees an RF link budget in excess of 140 dB besides a compelling output power up to +16 dBm, resulting in a robust and reliable communication link. The S2-LP is ready for SIGFOX™, Wireless M-Bus, 6LowPAN, and IEEE 802.15.4g networking connectivity, simplifying the design of IoT applications and enabling remote sensors to directly connect to the cloud without the need for a local gateway.

The kit comes in three variants (STEVAL-FKI868V1, STEVAL-FKI915V1, STEVAL-FKI433V1) to cover various frequency bands.
