Gravity: I2C BMI160 6-Axis Inertial Motion Sensor

Jargon buster

Plain-language definitions for the technical terms used above.

FIFO

FIFO stands for "first in, first out", a way of handling stored items so the oldest one is read out first, like a queue. In electronics a FIFO is usually a small buffer that temporarily holds data, such as sensor samples or serial bytes, so a processor can collect it in batches instead of reading continuously.

Gravity

Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.

Gyroscope

A gyroscope measures rotation, such as how fast a board is turning around its X, Y, and Z axes. This matters for projects like gesture controls, balancing robots, and motion tracking where tilt or rotation changes need to be detected.

I2C

I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.

zero-g offset

Zero-g offset is the small acceleration reading an accelerometer may show even when that axis should read 0 g. It matters because this error can affect tilt and motion measurements unless your software calibrates or compensates for it.
