SparkFun Triple Axis Accelerometer Breakout - LIS3DH

Jargon buster

Plain-language definitions for the technical terms used above.

12-bit resolution

12-bit resolution means the sensor’s measurement is divided into 4096 possible digital values. Higher resolution can make small changes in motion or tilt easier to detect, as long as the sensor range and noise are suitable for the project.

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 is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.

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.

LIS3DH

A specific low-power 3-axis accelerometer chip made by STMicroelectronics. Knowing the chip part number helps you find the correct datasheet, libraries, wiring details, and limits such as its safe voltage range.

microcontroller

A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.

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.

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.
