Fermion: LIS2DW12 Triple Axis Accelerometer Sensor (Breakout) (±16g)

Jargon buster

Plain-language definitions for the technical terms used above.

6D/4D orientation detection

6D/4D orientation detection is a sensor feature that recognises which way the board is facing, such as face-up, face-down, portrait or landscape positions. It matters if you want a project to react to being flipped, tilted or placed in a particular orientation without writing all the detection logic yourself.

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.

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.

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.

I2C address

An I2C address is the number a device uses so a microcontroller can tell it apart from other devices on the same I2C bus. It matters because two devices with the same fixed address may conflict if used together.

Motion detection

The ability to sense that something has moved, either by comparing successive camera frames or by using a dedicated sensor such as a PIR (infrared) or radar module. When a product lists motion detection, movement can be used as a trigger so a system only acts or records when there is activity rather than running continuously.

RMS

RMS is a way of describing the effective level of an AC signal, such as an audio output voltage. It helps compare audio output levels more meaningfully than a peak voltage number.

SPI

A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
