SparkFun Triple Axis Accelerometer Breakout MMA8452Q (Qwiic)

his 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.
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.
