BMX-055 9-axis motion sensor plus MS5637 pressure sensor with the SENtral EM7180 sensor fusion hub with M24512DFC EEPROM to store the SENtral configuration file. SENtral takes 9-axis accel/gyro/mag from BMX-055 and performs hardware sensor fusion returning raw data, quaternions, linear acceleration, and heading, etc. First attempt at using wafer-level, chip-scale package (WL-CSP). Breakout board using the SENtral with jumpers to take power from edge pins for breadboard use or to mount directly on the Teensy 3.1 for comparison between open-source software sensor fusion and the hardware sensor fusion provided by the SENtral. Four major digital components on a 0.5 in x 0.7 in board requires use of 0402 passive components and a lot of vias!
