Triple Axis Accelerometer Breakout – BMA180

Descripción

This is a breakout board for Bosch’s BMA180 three-axis, ultra-high performance digital accelerometer. The BMA180 provides a digital 14-bit output signal via a 4-wire SPI or I²C interface. The full-scale measurement range can be set to ±1g, 1.5g, 2g, 3g, 4g, 8g or 16g. Other features include programmable wake-up, low-g and high-g detection, tap sensing, slope detection, and self-test capability. The sensor also has two operating modes: low-noise and low-power.

This breadboard friendly board breaks out every pin of the BMA180 to an 8-pin, 0.1″ pitch header. The board doesn’t have any on-board regulation, so the provided voltage should be between 1.62 and 3.6V for VDD and 1.2 to 3.6V for VDDIO. The sensor will typically only consume 650uA in standard mode.

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
