MCU-117 High-Precision 9-Axis 10DOF Motion Tracking Module – MPU9250/MS5611, SPI/IIC Communication

Description

Product Overview

The MCU-117 High-Precision 9-Axis Motion Tracking Module is a powerful 10-degree-of-freedom (10DOF) inertial measurement unit (IMU) that combines a 9-axis MPU9250 sensor with a high-precision MS5611 barometer on a single compact board. This module is designed for applications requiring accurate orientation, altitude, and motion tracking, including drones, robotics, variometers, and navigation systems .

At its core, the MCU-117 integrates the InvenSense MPU9250 — a complete 9-axis motion tracking device featuring a 3-axis gyroscope, 3-axis accelerometer, and a 3-axis magnetometer — alongside the Measurement Specialties MS5611 high-resolution barometric pressure sensor . This combination provides a true 10DOF sensing solution (gyro + accelerometer + magnetometer + barometer) for comprehensive motion and environmental monitoring.

The module supports both I2C and SPI communication protocols, giving you flexibility to interface with a wide range of microcontrollers including Arduino, ESP32, STM32, and Raspberry Pi. Its compact footprint and low power consumption make it ideal for space-constrained and battery-powered applications such as quadcopter flight controllers, autonomous robots, variometers for paragliding, and wearable tracking devices .
