MMA8451 Accelerometer Breakout Board

SKU: BB2V10000011

The MMA8452Q is a smart low-power, three-axis, capacitive micro machined 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. You can detect motion, tilt and basic orientation with a digital accelerometer and the MMA8451 is a great accelerometer to start with. It has a wide usage range, from +-2g up to +-8g yet is easy to use with Arduino or another microcontroller.
