MMA7455 Digital Accelerometer - 3 axis - I2C/SPI interface
Description
The MMA7455 accelerometer breakout board provides a MMA7455 accelerometer and the associated circuitry.
Connecting this module to your microcontroller is easy with the SPI/I2C output - producing a simple digital signal rather than an analogue voltage.
The MMA7455L is a Digital Output (I2C/SPI), low power, low profile capacitive micromachined accelerometer featuring signal conditioning, a low pass filter, temperature compensation, self-test, configurable to detect 0g through interrupt pins (INT1 or INT2), and pulse detect for quick motion detection. 0g offset and sensitivity are factory set and require no external devices. The 0g offset can be customer calibrated using assigned 0g registers and g-Select which allows for command selection for 3 acceleration ranges (2g/4g/8g). The MMA7455L includes a Standby Mode that makes it ideal for handheld battery powered electronics.
