How to power 12V LED Strip with 5V USB via Computer Mouse Controller? Answered
Hello, I'm a electrical idiot, really appreciate it if you could explain in layman terms. I want to use the mouse electrical board, to power and control colours of my LED strip. This is for the chassis and random lighting. Note that I HAVE to use the mouse circuit board to control LED strip colours (Not Power Supply, but preferably so to reduce clutter)
So, I would have to remove the LED (which have 4 connections) from the mouse, and replace it with my LED strip via soldering wires. the connection would then be desktop/laptop pc - usb port - usb cable - mouse board - led strip (am I right?)
I bought 12V LED Strips with the following specifications below. I will only be using 3 sections in series, each section has 3 LEDs, total 9 LEDs. This means a total power requirement of 1.8Watts right? But the LED strip is 12V, whereas the USB mouse is 5V. Since its only 3 sections, is 5V sufficient? Again, i'm really noob at this.
The LED strip coincidentally also have 4 ports/wires. +12V, R, G, B. I'm assuming RGB ports are for the controllers, while +12V port is for the power supply.
