The GY-85 is a popular, low-cost Inertial Measurement Unit (IMU) breakout board. It is widely used in Arduino and Raspberry Pi projects for motion sensing, orientation tracking, and stabilization. However, unlike newer modules (such as the MPU-6050 or MPU-9250), the GY-85 does not use a single integrated chip. Instead, it combines three separate sensors from InvenSense and Hitachi.
