S2SPI ST Spirit 2 Wireless IoT Module Sub GHz 434M CE Approved

S2SPI-HA/UA/NA-A Module is designed based on S2-LP. S2-LP is a high performance ultra-low power RF transceiver, intended for RF wireless applications in the sub-1 GHz band. It is designed to operate in both the license-free ISM and SRD frequency bands at 433, 868 and 920 MHz, but can also be programmed to operate at other additional frequencies in the 430-470MHz, 860-940 MHz bands.

The S2-LP can be used in systems with channel spacing of 12.5/25 kHz enabling. The narrowband operations. The S2-LP shows an RF link budget higher than 140dB for long communication ranges and meets the regulatory requirements applicable in territories worldwide, including Europe, Japan, China and the USA.
