Frequently Asked Questions (FAQs)

1. What is the GY-91 sensor module used for?

The GY-91 is a 10-DOF (Degrees of Freedom) sensor module combining MPU9250 (accelerometer, gyroscope, magnetometer) and BMP280 (barometric pressure sensor). It’s commonly used in drones, robotics, motion tracking, and navigation systems.

2. Is the GY-91 compatible with Arduino and Raspberry Pi?

Yes, it is fully compatible with Arduino, Raspberry Pi, ESP32, and other microcontrollers via I2C interface.

3. What are the main components of the GY-91 module?

•MPU9250: 3-axis accelerometer, 3-axis gyroscope, 3-axis magnetometer

•BMP280: Barometric pressure and temperature sensor

4. What is the operating voltage of the GY-91 module?

It operates on 3.3V and communicates using I2C protocol.

5. Can I use this sensor for a drone flight controller?

Yes, the GY-91 is commonly used in flight controller boards for drones due to its 9-axis motion sensing and barometric pressure measurement.

6. Does it work with the Arduino IDE?

Yes, with the appropriate libraries installed (like MPU9250 and BMP280 libraries), it works seamlessly with the Arduino IDE.

7. How accurate is the BMP280 pressure sensor?

The BMP280 offers high precision and can also estimate altitude based on pressure changes.

8. Can this module measure orientation or tilt?

Yes, by using the accelerometer and gyroscope data, you can calculate tilt, pitch, roll, and orientation.

9. What is the communication interface used?

The GY-91 uses the I2C interface for communication. Some versions may also support SPI.

10. Do I need a logic level shifter to use with Arduino Uno?

If using a 5V board like Arduino Uno, it’s recommended to use a logic level shifter since the GY-91 operates at 3.3V.

11. What is the size of the GY-91 module?

It’s a compact breakout board, typically around 15mm x 20mm, suitable for space-limited projects.
