GY-91 10-DOF Multi-Sensor Module with MPU-9250 and BMP280

The GY-91 is a compact 10-DOF multi-sensor module that integrates the MPU-9250 motion-tracking unit and the BMP280 atmospheric pressure sensor. It combines a 3-axis gyroscope, 3-axis accelerometer, 3-axis magnetometer, and barometric pressure sensing on a single board with 16-bit data output. It is well suited to students, makers, and robotics enthusiasts developing orientation tracking, drone navigation, and wearable motion projects.

Complete motion and pressure tracking

The module pairs an MPU-9250 nine-axis device with a BMP280 barometer to measure triaxial acceleration, angular velocity, magnetic fields, and atmospheric pressure from 300 to 1100 hPa. It provides 16-bit data resolution across all measurement channels for accurate tracking.

Power and communication interfaces

Equipped with an internal low-dropout regulator, the module runs reliably from a 3 V to 5 V power supply. It supports standard I2C and SPI communication protocols for easy interfacing with microcontrollers.

Compact immersion gold board

Built using an immersion gold PCB and machine welding, the module measures just 14.3 mm by 20.5 mm with standard 2.54 mm pin spacing. Its low power consumption mode draws as little as 6.4 µA for the accelerometer, making it ideal for compact embedded designs.
