SVX-IMU-ICM-BMM-001
ICM-45686 + BMM350 9DoF Sensor Module
Compact 9DoF module with the TDK ICM-45686 six-axis IMU and the Bosch BMM350 magnetometer on one 2 × 7 header, with STM32G474 host examples for both sensors.
- ICM-45686 six-axis IMU: up to ±32 g and ±4000 °/s
- BMM350 three-axis magnetometer, ±2000 µT
- IMU on SPI or I²C, magnetometer on a separate I²C bus
- STM32G474 host examples for both sensors

Overview
SVX-IMU-ICM-BMM-001 gives a flight controller, robot or tracker nine axes of motion sensing on one small header: acceleration and angular rate from the TDK ICM-45686 and the magnetic field from the Bosch BMM350. The IMU connects over SPI or I²C with two interrupt lines and the magnetometer has its own I²C bus, so both can be sampled independently. The test pages show the wiring to the SaturnVex STM32G474 board and link to its ICM-45686 and BMM350 example projects.
