X-NUCLEO-IDS01A4 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-NUCLEOIDS01Ax (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 For further information contact your local STMicroelectronics sales office 1/7 www.st.com Schematic diagrams X-NUCLEO-IDS01A4 Table 1: Expansion board details 2/7 Evaluation board Identification resistors RF communication frequency Description X-NUCLEOIDS01A4 R14 mounted, R15 not mounted 868 MHz 868 MHz RF expansion board based on ETSI certified module SPSGRF-868 for STM32 Nucleo X-NUCLEOIDS01A5 R14 mounted, R15 not mounted 915 MHz 915 MHz RF expansion board based on FCC certified module SPSGRF-915 for STM32 Nucleo DocID027614 Rev 2 X-NUCLEO-IDS01A4 1 Schematic diagrams Schematic diagrams Figure 1: X-NUCLEO-IDS01A4 circuit schematic (1 of 3) MORPHO SX Connector MORPHO DX Connector CN7 PC1 0 PC1 2 VDD BOO T0 NC /PF6 NC /PF7 PA13 PA14 PA15 GN D PB7 PC1 3 PC1 4 PC1 5 PH0 /PF0/PD0 PH1 /PF1/PD1 VL CD /VBAT PC2 PC3 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 CN10 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 PC1 1 PD2 E5 V GN D NC / IOR EF RESE T +3V 3 +5V GN D GN D VIN NC / PA 0 PA 1 PA 4 PB 0 PC1 PC0 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 PC9 PB 8 PB 9 AV DD GN D PA 5 PA 6 PA 7 PB 6 PC7 PA 9 PA 8 PB1 0 PB 4 PB 5 PB 3 PA1 0 PA 2 PA 3 HE ADER 19 x2 Pass-Through: Female on Bottom and Male on Top CN5 ARDUINO SX Connector HE ADER 8 Pass-Through: Male on Bottom and Female on Top CN8 PA 0 PA 1 PA 4 PB 0 PC1 PC0 1 2 3 4 5 6 HE ADER 6 Pass-Through: Male on Bottom and Female on Top ARDUINO DX Connector 10 9 8 7 6 5 4 3 2 1 CN6 1 2 3 4 5 6 7 8 PC8 PC6 PC5 U5V PD8 PA1 2 PA1 1 PB1 2 PB11 /NC GN D PB 2 PB 1 PB1 5 PB1 4 PB1 3 AGN D PC4 NC /PF5 NC /PF4 HE ADER 19 x2 Pass-Through: Female on Bottom and Male on Top NC / IOR EF RESET +3V 3 +5V GN D GN D VIN 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 PB 8 PB 9 AV DD GN D PA 5 PA 6 PA 7 PB 6 PC7 PA 9 HE ADER 10 Pass-Through: Male on Bottom and Female on Top CN9 8 7 6 5 4 3 2 1 PA 8 PB1 0 PB 4 PB 5 PB 3 PA1 0 PA 2 PA 3 HE ADER 8 Pass-Through: Male on Bottom and Female on Top GSPG11032015DI0950 DocID027614 Rev 2 3/7 Schematic diagrams X-NUCLEO-IDS01A4 Figure 2: X-NUCLEO-IDS01A4 circuit schematic (2 of 3) J1 VCC _RF 3V 3 2 +3V 3 1 HE ADER 1x2 GN D PC7 PB 6 PB1 0 PB 3 R1 0 R2 0 R3 0 R4 0 SMD 080 5SPI1_ GP IO3 SMD 080 5 SMD 080 5 Not mounted SMD 080 5 CSN nS CLK PA 6 MISO PA 7 MOS I PA1 0 SDn PA 1 R5 0 SMD 080 5 Not mounted CSN PA 0 R6 0 SMD 080 5SPI1_ GP IO3 Not mounted PA 5 R7 0 SMD 080 5 Not mounted PA 4 R8 0 SMD 080 5SPI1_ GP IO2 Not mounted PB 0 R9 0 SMD 080 5SPI1_ GP IO1 Not mounted PC1 R10 0 SMD 080 5SPI1_ GP IO0 Not mounted CLK GSPG11032015DI0955 4/7 DocID027614 Rev 2 X-NUCLEO-IDS01A4 Schematic diagrams Figure 3: X-NUCLEO-IDS01A4 circuit schematic (2 of 3) SPSGRF-868 U1 ANT. 2 SPI1_ GP IO1 3 SPI1_ GP IO0 4 SP1_ GPIO3 SP1_ GPIO2 SPI_CS SP1_ GPIO1 SPI_MOSI SP1_ GPIO0 5 VCC _RF SDN VIN SPI_MISO SPI_CLK GN D 1 SPI1_ GP IO2 SPSGRF- 86 8 EEPROM SDn 10 CSN 9 MOS I 8 MISO 7 CLK 3V 3 1 1 11 6 SPI1_ GP IO3 R12 100 k SMD 080 5 8 2 2 C1 16 V 100 nF SMD 040 2 E_ PAD 9 4 /S C D Q GN D 1 6 5 2 nS CLK MOS I MISO VCC U2 GN D 3 7 /W /HO LD M95640 -RMC 6TG GN D SMD 080 5 PB4 R13 R14 0 R15 0 68 0 SMD 080 5 SPSGRF_868MHz SPSGRF_915MHz SMD 080 5 Not mounted D1 1 2 RED LED Digikey GN D 751 -1182 -1-ND Vishay TLMS 1100 -GS 08 SMD 060 3 GSPG11032015DI1000 DocID027614 Rev 2 5/7 Revision history 2 X-NUCLEO-IDS01A4 Revision history Table 2: Document revision history 6/7 Date Rev Changes 28-Apr-2015 1 First release. 28-May-2015 2 Updated board photo on the cover page.
