STEVAL-IDS001V4 STMicroelectronics

STEVAL-IDS001V4 Low cost, low data-rate short-range USB dongle transceiver in 868 MHz band based on the SPIRIT1 Data brief Description The STEVAL-IDS001V4 demonstration board is based on the SPIRIT1, which is a sub-GHz low power, low data-rate transceiver suitable for ISM bands and Wireless M-BUS. 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 STEVAL-IDS001V4 JTAG connector (not mounted) allows the development of specific firmware on the microcontroller. Features SPIRIT1 low power sub-GHz transceiver integrated in a USB dongle for direct PC connection External components tuned for 868 MHz band STM32L microcontroller Suitable for Wireless M-BUS systems 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 July 2013 DocID024931 Rev 1 1/7 For further information contact your local STMicroelectronics sales office. www.st.comSchematic diagram STEVAL-IDS001V4 1 Schematic diagram Figure 1.
