ARK 12S Payload Power Module

The ARK 12S Payload Power Module is a dual 5V 6A and 12V 6A power supply and digital power monitor designed for the Pixhawk Autopilot Bus Carrier boards.

This is similar to the ARK 12S PAB Power Module except that the additional 12V 6A supply allows easier powering of a payload.
