This SparkFun Triple-Axis Accelerometer Breakout is a simple Qwiic breakout for the KX132 digital accelerometer from Kionix. The KX132 is a low-power, 16-bit resolution three-axis accelerometer with four user-selectable acceleration measurement ranges of ±2g/4g/8g/16g and has up to a 10kHz (max) output data rate making it ideal for a wide range of acceleration measurements as well as high-speed applications such as vibration and tap sensing.

The KX132 includes a host of features including Freefall detection, Directional Tap^™ and Double-Tap^™ detection, tilt orientation detection and more. The Qwiic KX132 can interface with controllers using both I²C and SPI at high speeds so you can use it in an existing Qwiic/I²C chain or on a SPI bus.

The SparkFun Qwiic Connect System is an ecosystem of I²C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

Jargon buster

Plain-language definitions for the technical terms used above.

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.
ODR: ODR means output data rate: how often the sensor produces a new measurement. A higher ODR can capture faster motion or vibration, but it usually uses more power and creates more data for the microcontroller to handle.
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.
PTH: Plated through-hole means the pin holes are metal-lined so solder connects the pad on both sides of the board. It is useful for connectors and headers that need a strong mechanical and electrical connection.
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.
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.
