SparkFun Triple Axis Accelerometer Breakout - MMA8452Q (Qwiic)

This breakout board makes it easy to use the tiny MMA8452Q accelerometer communicate over I²C in your project. The MMA8452Q is a smart low-power, three-axis, capacitive MEMS accelerometer with 12 bits of resolution. This accelerometer is packed with embedded functions with flexible user programmable options, configurable to two interrupt pins. Embedded interrupt functions allow for overall power savings relieving the host processor from continuously polling data. This version of the SparkFun Triple Axis Accelerometer Breakout includes pre-soldered Qwiic connectors for rapid prototyping and better ease of use. With the connectors already soldered on, you can jump right into using this little board without any assembly!

The MMA8452Q has user selectable full scales of ±2g/±4g/±8g with high pass filtered data as well as non filtered data available real-time. The device can be configured to generate inertial wake-up interrupt signals from any combination of the configurable embedded functions allowing the MMA8452Q to monitor events and remain in a low power mode during periods of inactivity.

This board also breaks out the ground, power, I²C and two external interrupt outputs into 0.1" spaced pins.

Note: The I²C address of the MMA8452Q is 0x1D and is jumper selectable to 0x1C. A multiplexer/Mux is required to communicate to multiple MMA8452Q sensors on a single bus. If you need to use more than one MMA8452Q sensor consider using the Qwiic Mux Breakout.

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.
