Cansec S1SPI ST-Spirit 1 Module IoT Solutions Sub-GHz 434M//868M/915M IoT Low Power Consumption Module Low Cost

S1SPI-HA/UA/NA-A Module is designed based on Spirit1. The Spirit1 is a very low-power RF transceiver, intended for RF wireless applications in the sub-1 GHz band. It is designed to operate both in the license-free ISM and SRD frequency bands at 169, 315, 433, 868, and 915 MHz, but can also be programmed to operate at other additional frequencies in the 300-348 MHz, 387-470MHz, and 779-956 MHz bands. The air data rate is programmable from1 to 500 kbps, and the Spirit1 can be used in systems with channel spacing of 12.5/25 kHz, complying with the EN 300 220 standard. It uses a very small number of discrete external components and integrates a configurable baseband modem, which supports data management, modulation, and demodulation. The data management handles the data in the proprietary fully programmable packet format also allows the M-Bus standard compliance format (all performance classes). However, Spirit-1 can perform cyclic redundancy checks on the data as well as FEC encoding/decoding on the packets. The Spirit1 provides an optional automatic acknowledgement, retransmission, and timeout protocol engine in order to reduce overall system costs by handling all the high-speed link-layer operations.
