MMA8452 Triple Axis Accelerometer (2g/4g/8g)

PROAC-008452 Categories , ,


The MMA8452Q is a smart low-power, three-axis, capacitive MEMS accelerometer with 12 bits of resolution. It is packed with embedded functions with flexible user programmable options, configurable to two interrupt pins. Embedded interrupt functions allow for overall power savings which relieves the host processor from continuously power consumption. It has user selectable full scales settings of +-2g/+-4g/+-8g with high pass filtered data as well as non-filtered real-time data.

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