Generic Raspberry Pi-1031 4DOF Attitude Angle Sensor Module - I2C/SPI Interface

The Raspberry Pi-1031 module supports both I2C and SPI digital communication protocols. This dual-interface design provides flexibility for integration with a wide range of microcontrollers, including Arduino, Raspberry Pi, and ESP32. You can select the preferred protocol via hardware configuration (typically by setting address or chip-select pins).

The module operates from 3V to 5V DC. Its onboard logic is designed to be compatible with both 3.3V and 5V microcontroller systems, making it safe to connect directly to Arduino's 5V pins or Raspberry Pi's 3.3V GPIO. Always ensure your power supply is within this specified range for reliable operation.

To read data, connect the module's VCC, GND, SDA/SCL (for I2C), or MOSI/MISO/SCK/CS (for SPI) pins to your microcontroller. You will need to install the appropriate library for your platform (e.g., an IMU sensor fusion library for Arduino) to initialize the sensor and read the processed pitch, roll, and yaw angle values.

This 4DOF module specifically provides orientation sensing (pitch, roll, yaw) typically derived from a combination of a 3-axis accelerometer and a single-axis gyroscope or magnetometer. A 3DOF sensor might only measure tilt (pitch/roll), while a 6DOF IMU adds 3-axis gyroscope data for full rotational and linear motion tracking.
