STEVAL-IKR002V4B
SPIRIT1 - low data rate transceiver - 868 MHz - daughterboard
integrated balun
Data brief
Description
The STEVAL-IKR002V4B evaluation
daughterboard is based on the SPIRIT1, a sub-
GHz low power, low data rate transceiver suitable
for ISM bands and wireless M-BUS. The board is
equipped with external balun, matching and filter
in a single BALF-SPI-01D3 device which
optimizes size, RF performances and number of
external RF components (from 16 SMD passive
components to just 1).
Features
•
SPIRIT1 low power, sub-GHz transceiver in a
standalone RF module tuned for the 868/915
MHz bands
•
External balun + matching + filter in a single
component: BALF-SPI-01D3
•
Suitable for wireless M-BUS systems
•
Associated SPIRIT1 development kit includes
documentation, firmware for STM32L and GUI
•
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
•
