Help for Raspberry Pi Zero PCB

[vanepp]

You have three choices, with the current part you need to route the traces from the right of the RPI connector like this:

if that doesn’t do what you want (as in the case of trying to make a hat) then you either need to switch to this connector

Raspberry Pi 40pin Header

Here is a new update for this part. The change is all in pcb, the pads are now smaller so you can stack these and run standard 24mil traces between pins and have it pass the default DRC rules. [Capture] and the new part. I have a set of boards using this layout coming, so I can make sure the pads work in practice. Assuming they do I will change the RPI-4B to use this and then add this as an option to the parts factory for making headers. Raspberry-Pi-Header-40pin-improved.fzpz (14.8 KB) I h…

or to this new zero part which has that connector in it.

to use either of the last two solutions you will need to change the grid size in pcb like this:

in order to be able to position a standard trace between the pins without colliding with a pin.
