MPU9250 9-axis motion sensor + MS5637 Altimeter for mounting on the back pads of Teensy 3.1. Removed back plane ground beneath MPU9250 to reduce magnetometer interference.

ST Microelectronics' newest 9-axis motion sensor the LSM9DS1 plus Measurement Specialties' MS5611 pressure sensor with hardwired I2C. The board is designed to be either a mini Teensy 3.1 add-on board with SDA/SCL on pins 17/16 and power taken at the Teensy end, or the solder jumpers on the back can allow power to be taken from the edge of the board for convenient breadboarding like a traditional breakout board. The board is designed in mini-add-on mode to keep the hardware SPI pins free for other add-ons like an SD card or rf radio that must use SPI. One interrupt each from the accel, gyro, and mag is broken out and solder jumpers can allow access to the other two interrupts, if desired. Solder jumper can also be used to change the address of the LSM9DS1. Removed ground plane in LSM9DS1 sensor footprint to reduce interference with magnetometer.

LSM9DS0 9-axis motion sensor plus MS5637 pressure sensor micro add-on for Teensy 3.1 with hardwired I2C. Removed ground plane beneath LSM9DS0 per ST Microelectronics' recommendation to avoid squirrely magnetometer readings. Also moved traces as far as possible from sensor in an effort to reduce interference with the mag. Is it enough?
