Power Sense Module

$31.00

The Power Sense Module (PSM) provides analog current and voltage sensing to your Pixhawk autopilot mounted on your BlueROV2 or custom marine robotics project.

Please note: This new revision (since September 2021) is compatible with the current R3 revision of the BlueROV2, but has changes that are not compatible with older BlueROV2s. If you need a replacement for your older BlueROV2, please contact us at [email protected].

Description

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.
