SPSGRFC-433 Product Details

STMicroelectronics SPSGRFC Programmable Transceiver Modules are 1GHz transceiver certified modules that provide a complete RF platform. The SPSGRFC operate at the 433MHz, 868MHz, or 915MHz frequency band. The modules are CE, FCC, and IC certified and integrate wireless connectivity in target electronic devices without requiring particular RF experience or expertise. This certified solution optimizes time to market and are designed for maximum performance in a minimal space. The modules have 4 programmable I/O pins and an SPI serial interface with pin-to-pin and firmware compatible with the SPSGRFC-433 family.
