Hii guys,

I just got my bw car screen and tear it down
After that i found out that the motherboard is totally diffrend as others.
This is my first like big project and im totaly new to this so my question was is there someone that can help me out making it running 5v on the pi zero?

Here is a picture of the motherboard

Hmm. Never seen that one. At first I thought it was the same as this. But after looking closer they're different.

Search the forum a bit. You might find some info. This thread has lots of screen info too:

i suggest you test it first before modding.

Your board looks like its using XL1509, the same dc regulator as mine.

Look for the chip circled here

Desolder the positive red wire and directly connect it to PIN 2 of XL1509 chip. After this you can connect a 5v power but NOT 12v.

If you're not sure which one is the pin2, use a multimeter to check for 5v output voltage from each pin of XL1509.

Did you test it first before modding? Just to make sure it is working.

Haha just let it fall while working on it and broke the lcd.

I orderd a new one hopefully it will be a easier motherboard this time
