Overview:
The GFX sensor is a high-performance GPS and dynamic motion
sensor for use in on/off-highway vehicle applications. The unit
features an embedded GPS receiver and inertial measurement unit
(IMU) sensor with configurable outputs to meet the needs of a
variety of demanding applications.

1. Digital speed output is disabled at speed less than 1Kph
2. When digital speed output is disabled, output will be equal to supply input
(100% duty cycle).
Cautione:
Pay attention to Digital Output Pin Wiring. This pin should not be short
circuit with ground terminal.
