Freescale MMA7455 three axis digital acceleration sensor module, IIC/SPI interface, the new original chip! The integrated 5V to 3.3V chip on the board is more convenient for MCU system powered with 5V! MMA7455 digital acceleration sensor moduleMMA745 is a digital output (I2C / SPI), low power consumption, compact capacitive micromachined accelerometer with the function of signal conditioning, low-pass filter, temperature compensation, self-test, configuring or detecting 0g through the interrupt pin (INT1 or INT2), and pulse detection-offset, no external components. Customers can use the designated 0g registers and g-Select range selection to calibrate the 0g bias. This range can be chose three acceleration range (2g / 4g / 8g) via command. MMA745xL series has a standby mode, making it ideal for battery-powered handheld electronic devices. MMA7455 digital triaxial accelerometer module core is Freescale's MMA7455L digital triaxial acceleration sensor, the module is designed to use the official recommended design, circuit board through high electromagnetic compatibility design and optimization, with output precision, small size, reliable, various signposted, and good scalability characteristics. MMA7455L chip is mounted with a printed circuit board DIP pins (PCB) on which allows customers to integrate to a specific design application evaluate the product. So customers the flexibility to evaluate the device in their own hardware and software environment.. Module main parametersZ - shaft self testing- low voltage operation: 2.4V - 3.6V- the user who is used for bias calibration - a register- programmable threshold interrupt output- level detection mode motion identification (impact, shake, and free fall)- pulse detection mode single pulse or double pulse recognition- sensitivity 64 LSB/g @ /8g 2G 10 bit mode- the optional sensitivity of the 8 mode (2G, 4G, 8G)- reliable design, hig
