Hi Matt,

The minimum recommendation is 2.5A and that’s for driving the Minnowboard Max alone. For many high speed expansion lures you will need more than that. So you are right, you should test it with a bigger power supply.

Best regards,

B-O Bergman

Originally I got a power supply, but somehow confused myself and bought the wrong one, so I've been supplementing a 5V 1A power adapter that I had laying around until I get the correct power adapter that supplies enough Amperage.
