Re: Need help converting BW to 5V
For anyone who wants to try to mod this screen, i found a thread in a raspberry wiki: https://www.raspberrypi.org/forums/view ... &start=425

Re: Need help converting BW to 5V
Hi, I got this board form BW. Seems some sort of remix of the one you were discussing about in this topic.
One problem is that the number of one of the chips is scarcely visible. It is the one in yellow in the photo; in the detail photo the number seems to be MK 25D46BTIO 1720, but I'm not sure (the D could be a 0, and the 0s could be Os) and I can't find anything about it. Also, I can't find anything about the 7001 chip, too.
Here there are the datasheet of the other chips:
XL1509-5.0E1 (datasheet: http://www.alldatasheet.com/datasheet-p ... 5.0E1.html)
SS14 (datasheet: http://pdf1.alldatasheet.com/datasheet- ... /SS14.html - NOT COMPLETELY SURE!!)
How can I mod it to run 5v?

Re: Need help converting BW to 5V
Late to the party, but I can confirm Tobiwall's 5v mod works. Yes, you do need to completely remove the power regulating IC and solder a wire from the 5v pad to pin 6 of the IC pad.
Since there is no photo of the mod, this is what i did to make this particular board work:
Blue wire = 5v from VCC
Blue/White = Earth/Ground
Orange = Composite output from device (e.g. Raspberry Pi Zero)
Orange/White = Earth/Ground from output device (e.g Raspberry Pi Zero)
Full disclosure: I tried the mod without removing the IC on my first screen, but it died when I tried lowering the input voltage.

Re: Need help converting BW to 5V
I've got the same board as you - Did you work out how to get the board running on 5v ?HarryManback wrote: ↑Wed Jan 31, 2018 10:13 amHi, I got this board form BW. Seems some sort of remix of the one you were discussing about in this topic.

I'll do some investigation this evening hopefully I can find out how to do it, its so similar but slightly different at the same time.
