Bosch BMI423 Inertial Measurement Units

Bosch BMI423 Inertial Measurement Units (IMUs) offer an extended measurement range and low power consumption. Designed for always-on sensing in wearables, these IMUs combine a measurement range of ±32g and ±4000dps with on-sensor functions, including bone-conduction-based voice activity detection, gesture recognition, and step counting. These IMUs offer high precision, intelligent power management, advanced on-sensor functionality, and high-dynamic-range motion capture. Specifications include low noise levels, 25μA power consumption during acceleration operation, and flexible interfaces, including I3C, I2C, and SPI. Bosch BMI423 IMUs are available in a 2.5mm x 3mm x 0.8 mm3 LGA package, making them ideal for space-constrained designs.
