The new Accel SPI Board is a three-axis acceleration measurement tool that comes with an ADXL345 three-axis accelerometer circuit. This 3-axis acceleration tool is designed to measure the static acceleration of gravity in tilt-sensing applications as well as dynamic acceleration resulting from motion or shock. It comes with a selectable measurement range of 2g, 4g, 8g, or 16g. It is connected to the microcontroller on the development board through pad pins.
The Accel SPI Board operates on low power consumption and is thus, well-suited for mobile device applications. The Accel SPI Board with high resolution (4 mg/LSB) allows measurement of even less than 1.0' of change in inclination. The digital output data is formatted as 16-bit Twos Complement and is accessible via the industry-standard serial SPI communication interface. The Accel SPI Board is powered by embedded FIFO technology and thus, minimizes the host processor load. Designed for high performance, this compact-sized board is designed to operate using a 3.3V power supply only.
