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