Want to print this out for use on your header? I saved the image to my PC. Open with MSPaint. Go to Page Setup. Change your scaling to 18%. Print the image. Cut it out and press in place on your GPIO header…

clem57 I fully realize that you are not responsible for the RPi's deficient docs. And I thanked you earlier for your contribution to try to fill in the blank. You seem to think I'm criticizing you and…

I agree. It is quite moving that Element14's entire team, and Farnell/Newark, clem57 and others in the community do such a fantastic job supporting as best as they can, and get people up-to-speed on the…

The RX and TX pins are now connected to an 16550 compatible UART module known to Linux as /dev/ttyS0, while on earlier raspberry pi's it was a PL011, in Linux ttyAMA0. I'm not aware of any other changes, but that's just the one I need to invalidate that "nothing has changed".

Strangely there was a schematic of an earlier version released, then withdrawn ....
Luckily I come from a dial-up age where saving stuff locally was necessary.

I also cannot fathom why a schematic is so precious.
People assummed it was open source and maybe the original intention may have been, so the board layout is withheld.

Anyone that actually wants to copy it can, they simply need the broadcom chip and some time.

Asking for the specs is a reasonable request so that you can determine if your design will work.
Sadly some people think that guessing and a quick trial is good engineering.
