SPSGRF:Sub-GHz (868 or 915 MHz) low power programmable RF transceiver modules

The SPSGRF-868 and SPSGRF-915 are easy-to-use, low power sub-GHz modules based on the SPIRIT1 RF transceiver, operating respectively in the 868 MHz SRD and 915 MHz ISM bands.

The modules provide a complete RF platform in a tiny form factor.

The SPSGRF series enables wireless connectivity in electronic devices, requiring no RF experience or expertise for integration into the final product. As an FCC, IC, and CE certified solution, the SPSGRF series optimizes the time-to-market of end applications. The SPSGRF-915 is an FCC certified module (FCC ID: S9NSPSGRF) and IC certified (IC 8976C-SPSGRF), while the SPSGRF-868 is certified CE0051.

The modules are designed for maximum performance in minimal space and include 4 programmable I/O pins and SPI serial interfaces.
