STEVAL-IDS001V2 Low data-rate, short-range USB dongle transceiver in 315 MHz band based on the SPIRIT1 Data brief Description The STEVAL-IDS001V2 demonstration board is based on the SPIRIT1, which is a sub-GHz low power, low data-rate transceiver suitable for ISM bands. The board is equipped with an STM32L low power microcontroller to control the SPIRIT1. The board also features a USB connector for PC GUI interaction and firmware update. An optional JTAG connector (not mounted) allows the development of specific firmware on the microcontroller. STEVAL-IDS001V2 Features • SPIRIT1 low power sub-GHz transceiver integrated in a USB dongle for direct PC connection • STM32L microcontroller • External components tuned for 315 MHz band • Associated SPIRIT1 development kit includes: documentation, firmware for STM32L and GUI • Optional debug connector (not mounted) • USB interface • Modulation schemes: 2-FSK, GFSK, MSK, GMSK, OOK, and ASK • Air data rate: from 1 to 500 kbps • Very low power consumption (9 mA RX and 21 mA TX at +11 dBm) • Excellent receiver sensitivity performance (up to -118 dBm) • Low duty cycle RX/TX operation mode • Automatic acknowledgment, retransmission, and timeout protocol engine • AES 128-bit encryption co-processor • SPI interface for microcontroller • RoHS compliant June 2013 DocID024790 Rev 1 For further information contact your local STMicroelectronics sales office. 1/7 www.st.com 2 1 2 SMD 0402 10nF C19 SPI1_CS SPI1_CLK 1 2 3 4 5 3 Y1 SMD 0402 50V 12pF C17 50V SPI1_MOSI SPI1_MISO IRQ0_SPIRIT1 SMD 0402 330pF C3 1 IRQ1_SPIRIT1 SMD 0402 1 2 1 50V 10pF C18 SMD 0402 1 50V CAV2P SMD 0402 16V GND NX2016SA-52MHZ SPIRIT1 GPIO_0 SDO SDI SCLK CSn U2 C4 100nF SMD 0402 50V 2 1 C2 100pF IRQ2_SPIRIT1 C1 TBD SMD 0402 50V C20 1 2 3 4 IRQ1_SPIRIT1 IRQ0_SPIRIT1 IRQ3_SPIRIT1 IRQ2_SPIRIT1 GND 21 3.9 pF for 315 MHz 2.2 pF for 433 MHz 2.2 pF for 868 MHz 2 pF for 915/920 MHz Not Mounted for 315/433 MHz 22 nH for 868 MHz 15 nH for 915/920 MHz C14 TBD 50V SMD 0402 GND 15 SDN_SPIRIT1 14 13 12 11 L12 TBD SMD 0402 EXPAD SDN SMPS_Ext1 SMPS_Ext2 TX REXT 4 HEADER J3 1 L1 10uH SMD 0805 TBD L13 SMD 0402 TBD L2 TBD SMD 0402 L5 2 C15 2 L8 TBD TBD 1 1.2 pF for 315 MHz Not Mounted for 433/868/915/920 MHz SMD 0402 16V C10 10V SMD 0402 TBD C5 2 SMD 0402 TBD TBD 50V 2 C16 12 pF for 315 MHz 8.2 pF for 433 MHz NM for 868 MHz 7 pF for 915/920 MHz SMD 0402 50V C11 SMD 0402 12 nH for 315 MHz 10 nH for 433 MHz 0R0 for 868 MHz 5.1 nH for 915/920 MHz 1 L9 1 SMD 0402 TBD 27 pF for 315 MHz 18 pF for 433 MHz 8.2 pF for 868 MHz 2.4 pF for 915/920 MHz SMD 0402 50V TBD SMD 0402 L6 2 2 SMD 0402 330pF C7 TBD 50V 15 pF for 315 MHz 10 pF for 433 MHz 5.6 pF for 868 MHz 3.6 pF for 915/920 MHz SMD 0402 50V C13 15 nH for 315 MHz 6.2 nH for 433 MHz 2.7 nH for 868 MHz Not Mounted for 915/920 MHz 1 16V 15 nH for 315 MHz 10 nH for 433 MHz 4.3 nH for 868 MHz 0R0 for 915/920 MHz TBD 1 L10 1 16V SMD 0402 100nF C6 TBD C12 2 C8 SMD 0402 220pF 2 1.8 pF for 315/433 MHz 1.2pF for 868 MHz Not Mounted for 915 MHz 1 uF for 315/433/915/920 MHz 470 nF for 868 MHz TBD SMD 0402 12 nH for 315 MHz 8.2 nH for 433 MHz 3.0 nH for 868 MHz 3.6 nH for 915/920 MHz 1 SMD 0402 4.7 pF for 315 MHz 3.3 pF for 433 MHz 1.8 pF for 868 MHz 1.5 pF for 915/920 MHz 50V TBD 2 150 nH for 433 MHz 100 nH for 868/915/920 MHz SMD 0402 220 nH for 315 MHz 220 pF for 315/433/868 MHz 330 pF for 915/920 MHz 47 nH for 315 MHz 39 nH for 433 MHz 18 nH for 868 MHz 15 nH for 915/920 MHz 1 1 270 nH for 315 MHz 100 nH fo r 4 33 MHz 27 nH for 868/915/920 MHz 2 39 nH for 315 MHz 27 nH for 433 MHz 18 nH for 868/915 MHz SMD 0402 L11 10uH 2 1 10V IRQ3_SPIRIT1 20 19 18 17 16 1 2 1uF 2 1 2 4 2 1 1 2 1 2 2 2 1 1 2 GPIO_1 GPIO_2 GPIO_3 VR_DIG VDD_SMPS XOUT XIN VDD_DIG RFp RFn 6 7 8 9 10 1 1 VDD CAV1 2 1 2 1 1 2 1 2 DocID024790 Rev 1 2 220pF SMD 0402 2 C9 1 1 50V 50V GND1 GND 220pF SMD 0402 2 C36 U.FL connector 2 U6 SIG 1 2 3 1 2 1 2 2/7 1 L3 91 nH for 315 MHz 30 nH for 433 MHz 4.3 nH for 868 MHz 8.7 nH for 915/920 MHz L4 L7 TBD SMD 0603 1 33 nH for 315 MHz 16 nH for 433 MHz 8.2 nH for 868 MHz 7.5 nH for 915/920 MHz 2 TBD 390 nH for 315 MHz 220 nH for 433 MHz 47 nH for 868 MHz 39 nH for 915/920 MHz SMD 0603 TBD AM11DG-ST01 Mitsubishi 315/433/868/915 MHz ANT1 SMD 0603 TBD 2 1 2 Schematic diagram STEVAL-IDS001V2 Schematic diagram Figure 1.
