The SparkFun RedBot Accelerometer is an add-on sensor that provides bump and motion detection for the RedBot platform. It measures acceleration forces on the X, Y, and Z axes using the MMA8452Q triple-axis accelerometer, giving your robot awareness of its movements and orientation.
The sensor connects directly to the RedBot Mainboard via two 2×3 headers (one male, one female), allowing you to stack additional I²C sensors. Supported by the included RedBot library for easy bump and motion detection.

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.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- 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.
