BlueDot BMA400 Board

The BMA400 is an ultra-low power acceleration sensor from Bosch Sensortec, with a maximum current consumption of 14 µA. The output data rate ranges from 12.5 Hz to 800 Hz and the measurement range varies from ±2 g up to ±16 g. The BMA400 senses tilt, orientation, tab/double tab and enables step counting. 

Features:

• High Output Data Rate. Even with its ultra-low power consumption the BMA400 enables a very high output data rate of up to 800 Hz.
• 3.3 V and 5 V Power Supply. The on-board voltage regulator accepts anything from 2.6 V to 5.5 V to supply the BMA400 sensor with a constant voltage of 1.8V. 
• I2C Communication. The sensor communicates through the I2C protocol using the addresses 0x14 and 0x15 (default). 
• Data Transfer with both 5 V and 3.3 V devices. While devices like the Arduino Uno interpret a 5 V signal as a logic HIGH, the BMA400 uses 1.8 V as a logic HIGH. The on-board logic level converter translates the 5 V signals into 1.8 V signals and vice-versa.
