LCD Replacement for the Macintosh Portable

What inductor did you use on the RP2350's internal regulator? The RP2350 is very sensitive to what inductor is on the board and how it's arranged relative to the chip, to the point that Pi Foundation had a specific model of inductor custom manufactured with polarity markings so that people can make boards that run at max efficiency.

If you haven't verified your design against the official recommendations, you should. Also, make sure you have a pull-up on the RUN pin so that the chip isn't in reset all the time. This isn't really mentioned in that document and it matters (I learned the hard way).

I can see that you aren't using the recommended inductor layout. That may not be an issue but you should be aware of the potential for a non-functioning board.

If you've already ordered the boards, disregard this .

Unfortunantly, the boards have been ordered I didn't know the official recommendations existed! I never saw a hint of them, I only saw the datasheet.

But thankfully, that inductor they recommended should fit on the board where I have the pads for it. I will definitely be praying my board layout works! Thank you though for this valuable info!

Alright, I found a display that will fit kind of well, I don't need the display so I am not ordering it but for those that need it, it fits with the dimensions at least. Display I couldn't find any closer ones.

I am asking this, I would like 4 volunteer's for once the boards arrive, I would mail them to you. But they wouldn't come with almost any parts, maybe like 4, it might not work, considering the above post. But it's on it's way. Who would like to try it out? Pls PM.
