STEVAL-IDS001V2

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 STEVAL-IDS001V2 development of specific firmware on the microcontroller. 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 1/7 For further information contact your local STMicroelectronics sales office. www.st.comSchematic diagram STEVAL-IDS001V2 1 Schematic diagram Figure 1.
