Hi renanricha,
The exact specifics will depend on the controller. The ICM-1900 is the breakout, so you'll want to look at the Connecting Hardware chapter in your controller's user manual. Our TTL inputs are going to be pulsed up to a rail (typically 3.3V or 5V depending on controller) through a resistor. This means to activate them, simply short the input to the controller's digital ground.
