3-axis Accelerometer Module (MMA7260QT)

Page history last edited by sarith.ong@liquidware.com 8 years, 2 months ago

note: due to the discontinuation of the MMA7260QT chip, we redesigned a new version of the 3-axis accelerometer.


The 3-axis accelerometer module carries an MMA7260QT chip from Freescale. The MMA7260QT operates in 4 selectable sensitivity modes, +/- 1.5g, 2g, 4g, and 6g. It also offers a 1-pole low pass filter as well as temperature compensation. Furthermore, the MMA7260QT has a Sleep Mode function, ideal for use in portable, battery powered devices.

The accelerometer operates between 2.2 and 3.6V. Because of the low-voltage chips that have been damaged by 5V standard Arduino outputs, this board is equipped with built-in 5V tolerance protection.

The 3-axis accelerometer module comes as a kit with two 4-pin male headers, and is especially handy for determining sensitive changes in orientation.







  • Laptop PC: Freefall Detection
  • Cell Phone: Image Stability, Text Scrolling, Motion Dialing, E-Compass
  • Pedometer: Motion Sensing
  • Portable Handheld: Text Scrolling
  • Navigation and Dead Reckoning: E-Compass Tilt Compensation
  • Gaming: Tilt and Motion Sensing, Event Recorder
  • Robotics: Motion Sensing




  • Built-in 5V tolerance protection
  • Selectable Sensitivity (1.5g/2g/4g/6g)
  • Low Current Consumption: 500 μA
  • Sleep Mode: 3 μA
  • Low Voltage Operation: 2.2 V – 3.6 V
  • High Sensitivity (800 mV/g @ 1.5g)
