BW 3.5 TFT LCD - 5V modification

Post by schnauzbart » Sun Oct 07, 2018 8:56 am

Hi all,

I just started my first try on a GameBoy Zero.

Therefore i purchased this 3.5 inch tft lcd display from BW:
( ... op?ie=UTF8)

My problem here is, that the board doesn't fit any I found online.
It's similar to a Variant 2 but not really the same.

I've connected the display to 12V and 5V and measured out the voltage values on the chip, I suppose, is the DC/DC-converter.

In most guides the DC/DC-Converter is skipped by just connecting 5V to the VOUT pin.
My version however only has 4V output. I'm afraid that I will damage the board by connecting 5V to the pin I measured 4V.

Thank you for your answers!
