SparkFun 6DoF IMU Breakout - LSM6DSV16X (Qwiic)

Jargon buster

Plain-language definitions for the technical terms used above.

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.

edge computing

Edge computing means processing data close to where it is collected, such as on the device itself, rather than sending everything to the cloud. This can reduce delays, internet dependence, and privacy concerns in sensor, camera, and robotics projects.

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.

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.

I3C

I3C is a newer two-wire communication bus designed as a faster, more capable successor to I2C for sensors and small peripherals. It matters because I3C devices may offer better speed and features, but they need compatible hardware and software support.

IMU

An IMU (Inertial Measurement Unit) combines motion sensors, typically an accelerometer and gyroscope and sometimes a magnetometer, to measure movement and orientation. It can sense motion, tilt, vibration, rotation, and changes in direction, which is useful for tasks such as navigation, stabilisation, gesture detection, and asset tracking.

IoT

Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.

MIPI

MIPI is a high-speed display and camera interface often used inside phones, tablets, and embedded devices. It matters because raw MIPI displays usually need special driver hardware or software support, unlike plug-and-play HDMI screens.

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.

PCB

A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.

Qwiic

Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.

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.
