Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I have Grogster-Graeme's but it doesn't seem to jibe with what I see on the Waveshare 2040-Zero datasheet. Is there more than one design?

Mine are almost like your photo, although they are not Waveshare branded. Note that the bottom row from 14 down to 8 are all on 2.54mm centres and that you can't easily surface mount this board as the RP2040 is mounted on the bottom.

I have this drawn out as an SL6 macro if you'd like it.

Thanks Mick, I was sure that you had one because it was the Sweetie-Pi that made me look at Grogster's macro.

I modified his to this (which I think is the same as yours). Grogster's has different spacing between the side-holes and the bottom row:





This is all 2.54mm. Should be good, right?

Hi - that first image looks like it was not quite right, and as you say - does not really fit the module.  I suspect it made it into the makroes pack, as an early one, cos the correct one is the modified one, and yes - all on 2.54mm grid, but not suitable for breadboard mounting unless you leave the 5-pin header off.

An example of my use of the module on a board:

I managed to design a I2C game controller using one surface mounted, by cutting a notch out of the pcb and having the solder pads round the edges of the notch. It looks like it would work well, but you can't have components or tacks underneath it of course.
