96dB link budget.
• BALF-NRG-02D3 50ohm nominal input / conjugate match to BlueNRG transceiver
with integrated harmonic filter.
• LSM6DSO inertial digital module with 3-axis accelerometer and 3-axis
gyroscope. Ultra-low power (0.55mA in combo high-performance mode at the
highest datarate, 6.6kS/s). Configurable free-fall, wakeup, 6D/4D orientation
detection (to support portrait and landscape mode detection), single/double tap
recognition; automatic detection for activity/inactivity and stationary/motion
condition; advanced algorithms for pedometer, step detector and step counter;
significant motion and relative tilt; up to 16 finite state machines (FSM) to process
accelerometer, gyroscope or external sensor data. User selectable full scale of 2,
4, 8 or 16g and 125, 250, 500, 1000 or 2000dps; output data rates from 12.5 to
6600Hz, bandwidth up to 3kHz. The device includes 9KB FIFO buffer for 2 internal
sensors and up to 4 external sensors.
• LIS2MDL ultra low-power high-performance 3-axis magnetic digital sensor, 50
Gauss magnetic dynamic range. Selectable resolution/power trade-off. Output data
rate up to 150Hz. RMS noise down to 3mgauss in high-performance mode with
low-pass filter active. Embedded intrinsic offset cancellation. Embedded registers
for hard-iron offset subtraction. Configurable interrupt.
• LPS22HH ultra-compact piezo-resistive absolute pressure digital sensor, 260-
1260hPa, digital output barometer, full-mold, holed LGA package. The sensing
element, which detects absolute pressure, consists of a suspended membrane
manufactured using a dedicated process developed by ST.
• HTS221 capacitive digital sensor for relative humidity and temperature. The
sensing element consists of a polymer dielectric planar capacitor structure capable
of detecting relative humidity variations and is manufactured using a dedicated ST
process.
