    ICM42688

    BMI270: Accelerometer noise ~90 μg/√Hz; Gyroscope noise ~0.007 °/s/√Hz. ICM42688: Accelerometer noise ~75 μg/√Hz; Gyroscope noise ~0.004 °/s/√Hz. Overall, ICM42688 offers lower noise performance.

    46.0 mm x 46.0 mm

    Proceed to PCB planning: confirm 4-layer stackup, determine board outline from current component extents, define mounting hole strategy, and then begin component placement with priority on IMU and barometer proximity to MCU and analog ground.

    USB-C + XT60 6S with power-mux, buck to 5V, LDO to 3V3, VBAT divider and 60 A current sense into MCU ADC

    Schematic and core architecture defined; ready for layout planning.
