Homebuilt ROVs Forum

Hi all,

According to the Velleman K8023 manual, it needs 12V/300mA to operate. I was just wondering what kind of power source I should use to power that. Would a 12V car battery fry it? I'm just worried about supplying too much current and breaking it.

Any help would be greatly appreciated.

You can use a car battery, 12v 300mA means that you need a power supply that is able to deliver 300mA. It can be a good idea to use a 500mA fuse.

So if I understand this correctly, the board will draw exactly the 300mA it needs, regardless of the source? (providing the source can provide that much current, eg. the car battery)

Yes. That's correct.

Thanks for the answers! I just wanted to be sure before I continued with the project.
