DC motor HAT Question

Post by amartin88 »

Hello All,

I have a quick question I have been thinking about using the 5V DC electromagnet below
https://www.adafruit.com/product/3873
in conjunction with the Motor HAT mini Board.

I am thinking about using one of the motor drives that I currently can hook up to 5V power but the 1.2Amp (which is also supplied) is way over the spec of this electromagnet.

I would like thoughts on what I can do (I assume a resistor might be involved) as I am not sure what level of protection the motor port has on the motor HAT board.

Thanks for your guidance and love you guys (Adafruit team!)

Andrew

1.2A is just the maximum that the HAT can safely deliver. The actual current flow is determined by the load and the source voltage. If supplied with 5v, the magnet will only pull 0.3A.

thank you, that was my original thought but always thinking I will blow something up.

Thanks,
