Sub-GHz low-power-programmable RF module

(SPSGRF-868 or SPSGRF-915)

Two modules are available depending on the frequency of the Sub-GHz module (M3). The

SPSGRF-868 and SPSGRF-195 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 (foot print of this module is

13.5 mm x 11.5 mm). The SPSGRF-915 is an FCC certified module (FCC ID: S9NSPSGRF)

and IC certified (IC 8976CSPSGRF), while the SPSGRF-868 is certified CE0051.

The modules include four programmable I/O pins and an SPI serial interface (SPI3 of

STM32L475VG).
