Introduction

This is a tiny MMA8452Q accelerometer breakout board, The MMA8452Q is a smart low-power, three-axis, capacitive MEMS accelerometer with 12 bits of resolution. it packs 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. It has user selectable full scales of +-2g/+-4g/+-8g with high pass filtered data as well as non filtered data available real-time.

This board breaks out the ground, power, I2C and two external interrupt pins, which make it easy to use in project.
