X-NUCLEO-IDS01A4 STMicroelectronics

X - N U C L E O - I D S 0 1 A 4 Sub-1 GHz RF expansion board based on the SPSGRF-868 module for STM32 Nucleo Data brief Description The X-NUCLEO-IDS01A4 is an evaluation board based on the SPIRIT1 RF module SPSGRF-868 expansion of STM32 Nucleo boards. The SPSGRF-868 module operates in the 868 MHz ISM band and is ETSI certified. Identification of the operating frequency of the X-NUCLEO- IDS01Ax (x=4 or 5) is performed through two resistors (R14 and R15). It is compatible with the MORPHO and Arduino UNO R3 connector layout. The X-NUCLEO-IDS01A4 interfaces with the STM32 microcontroller via SPI connections and GPIO pins. The user can change some of the GPIOs by mounting or removing the resistors. Features STM32 Nucleo expansion board based on the SPSGRF-868 SPGRF-868 characteristics: 868 MHz ETSI-certified module based on low power, low data-rate sub-1 GHz SPIRIT1 transceiver Integrated Balun (BALF-SPI-01D3) Chip antenna Compatible with STM32 Nucleo boards Equipped with Arduino UNO R3 connectors Scalable solution capable of cascading multiple boards for larger systems Example firmware for point-to-point communication, compatible with STM32Cube firmware RoHS compliant May 2015 DocID027614 Rev 2 1/7 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagrams X-NUCLEO-IDS01A4 Table 1: Expansion board details Evaluation Identification RF communication Description board resistors frequency 868 MHz RF expansion board X-NUCLEO- R14 mounted, R15 868 MHz based on ETSI certified module IDS01A4 not mounted SPSGRF-868 for STM32 Nucleo 915 MHz RF expansion board X-NUCLEO- R14 mounted, R15 915 MHz based on FCC certified module IDS01A5 not mounted SPSGRF-915 for STM32 Nucleo 2/7 DocID027614 Rev 2
