Product Overview

Sub-GHz transceiver development kit based on the SPIRIT1 (169MHz band). This development kit includes 2 RF daughter boards based on the SPIRIT1 low power, sub-GHz low data rate transceiver suitable for ISM bands and 2 motherboards based on the STM32L low power microcontroller to control the daughter boards. 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.
  • Associated SPIRIT1 software development kit with documentation, STM32L firmware and GUI
  • Debug connector, USB interface, SPI interface for microcontroller
  • Modulation schemes: 2-FSK, GFSK, MSK, GMSK, OOK and ASK
  • Air data rate from 1 to 500Kbps
  • Very low power consumption (9mA RX and 21mA TX at +11dBm)
  • Excellent performance of receiver sensitivity (up to -120dBm)
  • Low duty cycle RX/TX operation mode, AES 128bit encryption co-processor
  • Automatic acknowledgment, retransmission and timeout protocol engine
