Gravity: I2C LIS2DW12 Triple Axis Accelerometer Sensor (±2g/±4g/±8g/±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.

FIFO

FIFO stands for “first in, first out” and is a small memory buffer inside the sensor that stores recent readings in order. This matters because it can help capture motion data without the microcontroller needing to read the sensor every single instant.

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.

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

A camera feature that checks the image for changes that suggest something has moved. It matters because your project can use movement as a trigger instead of constantly saving or processing every frame.

UART

UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
