3-Axis Orientation/Motion Detection Sensor
The MMA7660FC is a ±1.5g 3-Axis Accelerometer with Digital Output (I2C). It is a very low power, low profile capacitive MEMS sensor featuring a low pass filter, compensation for 0g offset and gain errors, and conversion to 6-bit digital values at a user configurable samples per second. The device can be used for sensor data changes, product orientation, and gesture detection through an interrupt pin (INT). The device is housed in a small 3mm x 3mm x 0.9mm DFN package.

RD3803MMA7660FC評估板
RD3803MMA7660FC is designed to provide the user with a complete out of the box experience to buate the MMA7660FC, a low power, 3-axis linear accelerometer with I2C digital output. An accelerometer daughter board plugs directly into the communication board for buation of the MMA7660 accelerometer and its functions. The accelerometer daughter board can be removed for customer prototyping and is also available to order separaby as KIT3803MMA7660FC.
The KIT3803MMA7660FC is an accelerometer daughterboard designed with all the accelerometer pins connected directly to a standard DIP socket for fast system prototyping and device buation within the users application. This sensor daughterboard is also available in the RD3803MMA7660FC development kit that includes the daughterboard along with the MCU communicator board.
RD3803MMA7660FC評估板包括:
Communication board containing a Freescale MCU and USB interface which enables the communication with a PC
Accelerometer daughter board with MMA7660FC accelerometer
Graphical user interface (GUI) for demonstrating all integrated accelerometer features as well as software routines for specific applications.
USB Connector
Sensor CD containing pertinent application notes, datasheets, software and sensor bs
KIT3803MMA7660FC 包括:
Accelerometer DIP board with MMA7660FC accelerometer
Sensor CD containing pertinent application notes, datasheets, software and sensor bsFC development kit that includes the daughterboard along with the MCU communicator board.
The RD3803MMA7660FC Evaluation kit is a complete out of the box experience tool to buate the MMA7660FC, a low power, 3-linear smart accelerometer with I2C digital output. The accelerometer contains both a communication board and a DIP board that has the sensor that plugs into the communication board (Figure 1). Providing the DIP as a separate component allows the capability to buate the sensor using the communication board and/or on the target customer application. This application note is an in-depth document explaining the setup and installation of the board and GUI and a thorough debion of the demos included in the GUI.
