Design a Custom BoardThe BMI323 is a compact 6-degree-of-freedom inertial measurement unit integrating a 16-bit triaxial accelerometer (±2 to ±16g) and 16-bit triaxial gyroscope (±125 to ±2000°/s) with temperature sensing. It features I2C, SPI, and I3C interfaces, ultra-low power consumption (790µA typical), and built-in motion detection and gesture recognition for wearable and mobile applications.
This 3x5mm LGA-14 package requires reflow soldering and features 0.8mm pitch pads underneath the component, making it impossible to breadboard directly or hand-solder reliably. A breakout board exposes all 14 pins to standard 2.54mm headers, enabling prototyping with I2C/SPI accelerometer and magnetometer modules while eliminating the need for surface-mount assembly skills.
