GY-91 10DOF 4 Sensors in 1 Module with MPU-9250 and BMP280

GY-9110DOF 4 Sensors in 1 Module with MPU-9250 and BMP280 description

This small 10-DOF sensor module GY-91 is more compact than the GY-80 module.
The module uses a unique MPU-9250 chip combination with built-in 3-axis gyroscope, 3-axis accelerometer, digital compass and BMP280 enhanced barometric pressure sensor.
The MPU-9250, delivered in a 3x3x1mm QFN package, is the smallest 9-axis MotionTracking device in the world and incorporates the latest InvenSense design innovations, allowing dramatically reduced chip size and power consumption, while improving the performance and the cost. Enhancements include low-power accelerometer mode support with only 6.4μA of and provides improved 16-bit compass data resolution (0.15 μT per LSB).
The full-scale measuring range of ± 4800μT helps alleviate the challenges of compass placement in complex PCBs.
