Tiny-module

This module is used to power the Pixhawk 3 Pro autopilot with a stabilized voltage.

It is also able to measure the overall consumption of your system using its Hall effect sensor. It is able to safely charge up to 200A (according to version).

The module is equipped with a LED indicator to warn you if there is a power problem.

You will find more information on this page.

HARDWARE

Please connect the power module to the "Power 1" port on the Pixhawk.

For redundancy, it is possible to use a second module with another battery, all connected to the port "Power 2" of the Pixhawk.

In this case, the autopilot uses only the first module for its own power supply. On the other hand, if the first module were to be broken, the autopilot switches directly to the second one.
