The GY-85 uses the to communicate with microcontrollers like Arduino or Raspberry Pi. Each sensor has its own unique 7-bit address: gy-85 datasheet pdf
Some low-quality clones swap pins 7 and 8. Always verify with a multimeter before soldering. // Initialize ADXL345 (set power control) Wire
The is a 9-axis (9DOF) Inertial Measurement Unit (IMU) sensor module. It is actually a breakout board that combines three separate sensor chips into one package to provide motion tracking and orientation data. // Power control register Wire.write(0x08)
