Gyroscope and Accelerometer in one with Headers

Jargon buster

Plain-language definitions for the technical terms used above.

6-axis motion tracking

A way of measuring movement using three rotation axes and three acceleration axes. It matters because it lets a project estimate tilt, orientation, vibration, and gestures from one module rather than using separate motion sensors.

ADC

An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.

breakout

A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.

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.

Headers

Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.

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.

MEMS accelerometer

A tiny motion sensor made using micro-electromechanical systems technology that measures acceleration and tilt. In a compass module, it helps correct the heading when the board is not perfectly flat.

MEMS gyroscope

A MEMS gyroscope is a tiny motion sensor made using micro-scale mechanical parts on a chip. It lets a small, low-power module measure rotation without needing a large mechanical gyro, which is useful for compact electronics projects.

MPU

MPU can refer to a few different things in electronics: a microprocessor unit (a processor powerful enough to run a full operating system such as Linux, with external memory and storage), a motion-processing unit like the MPU-6050 or MPU-9250 inertial sensor modules, or a memory protection unit built into some microcontrollers. The intended meaning depends on the surrounding context.

MPU-6050

A combined motion-sensing chip that includes a 3-axis accelerometer and a 3-axis gyroscope. The exact chip name matters because it determines the available ranges, data format, and example code or libraries you can use.
