Homebuilt ROVs Forum

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

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)

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.

Thanks! That cleared things up a lot.

Recently, I undertook an ROV project and I decided to use the Velleman K8023 kit to control a couple of pumps via relays. My question is, does the receiving end (the larger board) only need a 12VDC power source? From what I can tell you need 12VDC to power your devices, however does that same power ...
