STEVAL-IKR001V8D
SPIRIT1- low data rate transceiver - 868 MHz - daughterboard range extender
Data brief
Description
The STEVAL-IKR001V8D demonstration board is
based on the SPIRIT1, a sub GHz low power, low
data rate transceiver suitable for ISM bands and
wireless M-BUS systems.
The STEVAL-IKR001V8D includes an external
power amplifier from SkyWorks®, which allows
the application to reach +27 dBm (500 mW)
output power.
STEVAL-IKR001V8
Features
• SPIRIT1 low power sub GHz transceiver in a
standalone RF module tuned for 868 MHz
band with external power amplifier
• Associated SPIRIT1 development kit, including
documentation, firmware for STM32L and GUI
• Suitable for wireless M-BUS systems
• Modulation schemes: 2-FSK, GFSK, MSK,
GMSK, OOK, and ASK
• Air data rate from 1 to 500 kbps
• TCXO for narrow band requirements
• Max POUT +27 dBm
• Excellent receiver sensitivity (up to -123 dBm)
• TX power consumption @ +27 dBm: 350 mA
• SAW filter in reception path to prevent
interference from out-of-band signals
• SkyWorks® SEXXXXSL power amplifier
• Low duty cycle RX/TX operation mode
• Automatic acknowledgment, re-transmission
and timeout protocol engine
• AES 128-bit encryption co-processor
• SPI interface for microcontroller
• RoHS compliant
