STMicroelectronics X-NUCLEO-IDS01A4 Sub-1 GHz RF Expansion Board | SPSGRF-868 868MHz Shield | For STM32 Nucleo IoT Wireless
Description
SPIDER Automation STMicroelectronics X-NUCLEO-IDS01A4 Sub-1 GHz RF Expansion Board offers developers an efficient, ready-to-use radio frequency evaluation platform for wireless embedded applications. Powered by the SPSGRF-868 certified module, the board operates within the 868 MHz ISM frequency band, making it fully compliant with ETSI regulations for European deployments.
The core of the module is driven by STMicroelectronics’ ultra-low-power SPIRIT1 sub-1 GHz RF transceiver, paired with an integrated balun and a compact chip antenna to guarantee stable impedance matching and reliable signal propagation. The expansion board interfaces effortlessly with any STM32 Nucleo host board through SPI connections and configurable GPIO pins. Complete with sample firmware for robust point-to-point communication compatible with STM32Cube libraries, the X-NUCLEO-IDS01A4 accelerates the development of smart metering, home automation, and industrial telemetry systems.
