Detailed Description

Driver for the EagleTree Systems Altitude Sensor. Has only been tested with V3 of the sensor hardware.

Notes: Connect directly to TWOG/Tiny I2C port. Multiple sensors can be chained together. Sensor should be in the proprietary mode (default) and not in 3rd party mode. Pitch gains may need to be updated.

Sensor module wire assignments: Red wire: 5V White wire: Ground Yellow wire: SDA Brown wire: SCL
