BMI088 + BMM350 9DoF Sensor Module
Compact 9DoF module with the Bosch BMI088 six-axis IMU and the BMM350 magnetometer on one 2 × 8 header, with STM32G474 host examples for both sensors.
- BMI088 six-axis IMU: ±24 g and ±2000 °/s, built for vibration
- 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-BMI-BMM-001 gives a flight controller or robot nine axes of motion sensing on one small header: acceleration and angular rate from the Bosch BMI088, an IMU designed for high-vibration platforms such as drones, and the magnetic field from the Bosch BMM350. The BMI088 connects over SPI with separate accelerometer and gyroscope chip selects (or I²C) and the magnetometer has its own I²C bus, so all sensors can be sampled independently. The test pages show the wiring to the SaturnVex STM32G474 board and link to its BMI088 and BMM350 example projects.
