The Power Sense Module (PSM) provides analog current and voltage sensing to your Pixhawk autopilot mounted on your BlueROV2 or custom marine robotics project.
The Power Sense Module (PSM) provides analog current and voltage sensing to your Pixhawk autopilot mounted either on your BlueROV2 or custom marine robotics project. The ArduSub firmware for the Pixhawk supports the Power Sense Module and through QGroundControl will give you visual indications of battery level and current consumption.
This module uses a hall effect current sensor for excellent accuracy at low current draw.
Unlike standard power modules for the Pixhawk, the Power Sense Module will NOT provide 5V power, only sensing abilities. On the BlueROV2, the Pixhawk is powered from multiple sources so this 5V power supply is not needed.
