I am building a custom "TV Set" which is essentially a 3D printed enclosure containing a raspberry, a 10 inch screen and a LED light that lights up a logo on the back.
Now I am a newbie when it comes to power supply stuff.
I have a 12V 2.1A power supply but I suspect this could not be enough?
The screen is this one https://bit.ly/2uw9GYH which says 12V 2A
Then the raspberry need 5V 2A
and then there's a LED cob light thats 5V 1A
I do have a stepdown converter module to get from 12v to 5v for the raspberry
Now for the power supply, do just need to add up the Amperes?
So 2A + 2A +1A = 5A? Do I need a 12v5A powersupply?
Or how does this work?
Thanks for your help
