• DESCRIPTION

  It's low-cost, but has just about every 'extra' you'd want in an accelerometer:

  • Three axis sensing, 10-bit precision
  • ±2g/±4g/±8g/±16g selectable scaling
  • Both I2C (2 possible addresses) and SPI interface options
  • Interrupt output
  • Multiple data rate options 1 Hz to 5Khz
  • As low as 2uA current draw (just the chip itself, not including any supporting circuitry)
  • Tap, Double-tap, orientation & freefall detection
  • 3 additional ADC inputs you can read over I2C

  We kept seeing this accelerometer in teardowns of commercial products and figured that if it's the most-commonly used accelerometer, its worth having a breakout board!

  There's an address selection pin so you can have two accelerometers share an I2C bus.

  To get you going fast, we spun up a breakout board for this little guy. Since it's a 3V sensor, we add a low-dropout 3.3V regulator and level shifting circuitry on board. That means its perfectly safe for use with 3V or 5V power and logic. It's fully assembled and tested.  Comes with a bit of 0.1" standard header in case you want to use it with a breadboard or perfboard.  Two 2.5mm (0.1") mounting holes for easy attachment.
