The ADXL345 is a small, thin, low power, 3-axis MEMS accelerometer with
high resolution (13-bit) measurement at up to +/-16 g. Digital output
data is formatted as 16-bit twos complement and is accessible through
either a SPI (3- or 4-wire) or I2C digital interface.
The ADXL345 is well suited..
is a breakout board for Honeywell’s HMC5883L, a 3-axis digital compass.
Communication with the HMC5883L is simple and all done through an I2C
interface. There is no on-board regulator, so a regulated voltage of
2.16-3.6VDC should be supplied.Features:Simple I2C interface2.1..
