This module will provide power to your project via main and backup power sources.

You connect the two power sources to the module and it will do the following:

• When your main source is working properly it will provide you circuit power from this source.
• When your main source goes offline it will automatically disconnect the main source and connect to backup source.
• When your main source come back online it will automatically disconnect the backup source and goes back to the main source.

The two source are completely isolated for safety reasons.
