Frequently asked questions

How can I verify the correct I2C configuration?
Check the datasheet for I2C specifications and ensure that SDA and SCL lines are correctly configured.

What specifications should I check before starting?
Check the datasheet for power supply voltages and maximum currents.

Can I use this module to measure the speed of an object?
No, this module measures orientation and height, not direct speed.

What are the precision limits of the sensors?
Check the datasheet for sensor precision for expected values.
