Simple Teensy 3.1 add-on board to test the relative performance of various state-of-the-art MEMS pressure sensors. Included is Invensense’s 3.5 mm x 3.5 mm ICM20730 7-axis motion sensor with accel/gyro and embedded pressure sensor, Bosch’s 2.5 mm x 2 mm BMP280, ST Microelectronics' 2.5 mm x 2.5 mm LPS25H, and Measurement Specialties' 3 mm x 3 mm MS5637. Broken out are all interrupts (ICM20730 and LPS25H) and all I2C device address bits (ICM20730, BMP280, and LPS25H) to avoid address conflicts. Also broken out is the ICM20730 FSYNC pin to test electronic image stabilization. Added bypass caps on ICM20730 VDD and VDDIO.
