STMicroelectronics SPIRIT1 | Demoboard STEVAL-IKR002V4

Low cost, low data-rate short-range USB dongle transceiver in 868 MHz band based on the SPIRIT1

Overview

TopologyOther Topology
IC revision1

Description

The STEVAL-IKR002V4 development kit includes 2 RF daughterboards based on the SPIRIT1 low power, sub-GHz low data rate transceiver suitable for ISM bands and wireless M-BUS, and 2 motherboards based on the STM32L low power microcontroller to control the daughterboards.Each motherboard features a USB connector for PC GUI interaction and firmware updates. A JTAG connector allows the development of specific firmware on the microcontroller.

Features

  • 2 SPIRIT1 low power, sub-GHz RF transceiver daughterboards tuned for the 915 MHz band
  • 2 STM32L microcontroller-based motherboards
  • Suitable for wireless M-BUS systems
  • Associated SPIRIT1 software development kit with documentation, STM32L firmware and GUI
  • Debug connector
  • 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 performance of receiver sensitivity (up to -120 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

Typical applications

  • Industrial monitoring and control
  • Home and building automation
  • AMR (automatic meter reading) / WSN (wireless sensors network) / Wireless fire and security alarm systems / Point-to-point wireless link
