==Introduction==
This is a breakout board for BOSCH BMA180 digital triple axis accelerometer.BMA180 is a digital ultra-high-performance tri-axial low-g acceleration sensor for consumer
market applications. It allows measurements of static as well as dynamic accelerations with very
high accuracy. Due to its three perpendicular axes it gives the absolute orientation in a gravity
field. As all other Bosch inertial sensors, it is a two-chip arrangement (here in a plastic
package). An ASIC evaluates the output of a three-channel micromechanical acceleration-
sensing element that works according to the differential capacitance principle. The underlying
micromachining process has proven its capability in much more than 100 million Bosch
accelerometers and gyroscopes so far.

The BMA180 provides a digital full 14 bit output signal via a 4-wire SPI or I2C interface. With an
appropriate command the full measurement range can be chosen between 1 g and 16 g. A
second-order Butterworth filter with switch-able pole-frequencies between 10 Hz and 600 Hz is
included to provide pre-conditioning of the measured acceleration signal. Typical noise level
and quantization lead – in 2 g-mode - to a resolution of typically 0.5 mg and a typical accuracy
of below 0,25° in an inclination sensing application, respectively. The current consumption is
typically 650 μA at a supply voltage of 2.4 V in standard mode. Furthermore, the sensor can be
switched into a very low-power mode where it informs the host system about an acceleration
change via an interrupt pin. This feature can be used to wake-up the host system from a sleep
mode.

The sensor also features self-test capability. It is activated via SPI/I2C command, which results
in a physical deflection of the seismic mass in the sensing element due to an electrostatic force.
Thus, it provides full testing of the complete signal evaluation path including the micro-machined
sensor structure and the evaluation ASIC.

==Features==
*Wide variety of measurment ranges (±1g, 1.5g, 2g, 3g, 4g, 8g and 16g)
*14- or 12-bit ADC conversion
*2 selectable I2C addresses
*Programmable integrated digital filters (no external components necessary)
**8 low-pass filters
**1 high-pass filter
**1 band-pass filter
*Programmable interrupt features:
**Wake-up
**Low-g detection
**High-g detection
**Tap sensing
**Slope detection
*2 main standard modes: low-noise and low-power
*Sleep mode
*Wake-up mode
*Self-test capability
