Powering my mirror?
-
@MadScientist will this be on the back of the screen it’s self?
-
Here’s an example from my LCD that I am going to use for my mirror
The M240HW01 V.D. is the LCD model and AU Optronics is the manufacturer.
Btw, for the future: A V56 or V59 controller board are already available for less than 8€ incl. shipping and the firmware can be changed easily by USB. It has other disadvantages though, like not waking up automatically once the HDMI port is re-activated. -
@MadScientist wouldn’t that be the LTN170WX-L08 that i had to look up to find it? And thanks for the info on universal boards. Though I think I want the auto wake feature.
-
Yeah, I saw after I replied. I checked the datasheet and if I do not misunderstand the information, your screen should be at around 10W (max.). The board will probably take some, too. But you should be more than fine with a 30W power supply.
-
@MadScientist with the pi and all?
-
That should be enough for all if you don’t have more than the LCD, Raspberry Pi and the step-down module. You should check the power consumption of the LED strips, if you’re planning to use some. If not, you should be good with 30W.
-
@MadScientist
Will both the LCD and the step down wire to the same wire? Will this lower the 12 volts from the lcd? -
You split the 12V output of your power supply. One set of wires (plus and Gnd) goes to your LCD controller board (check polarity!) and one set to your step-down-converter, which is regulated to 5.1V for the Pi.
-
My point is that all the power supply’s under 80W only have one set of output wires.
-
Just use luster terminals.
