The Adafruit ADXL375 is a high-G triple-axis accelerometer capable of measuring up to ±200g of force. It communicates via I2C or SPI and includes STEMMA QT connectors for solderless I2C connections. An on-board 3.3V regulator and logic-level shifting make it compatible with both 3.3V and 5V microcontrollers.
The ADXL375 shares the same form factor and interface as the ADXL345 and ADXL343, but with a fixed ±200g range instead of selectable lower ranges. Existing library code for the ADXL345/ADXL343 will work with only a scaling adjustment, making migration straightforward.
Key Features

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- 3.3V regulator
- A 3.3V regulator is a power circuit that provides a steady 3.3 volts for parts that need that supply voltage. On a breakout board, it can let the sensor run safely even when the connected microcontroller or power source uses a higher voltage.
- 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.
- logic-level shifting
- Logic-level shifting converts digital signals between voltage levels, such as 3.3V and 5V. It matters because it helps the module connect safely to microcontrollers that use different logic voltages.
- 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.
- 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.
- STEMMA
- A plug-and-cable connection system used on some maker electronics boards to make wiring simpler. If a product uses STEMMA, you need the matching cable or connector type to plug it in without soldering.
- STEMMA QT
- A small plug-in connector system for I2C boards that lets you connect compatible sensors and controllers without soldering. It matters because it can make wiring faster and less error-prone, especially when adding several small modules to a project.
