Reply To: Connectors for 20-pin headers

There is a Mayfly Protoshield rev1 – but I can’t find if its for sale anywhere.

I have one, and no plans for it right now so if you wanted it I could send it to you.

The details are here, but no gerbers.  With gerbers it would be possible to order the base boards directly from oshpark.com

I have a base board defined in my PCB package, I could look at what it would take to generate a PCB  and then you could order it directly.

This would be the simplest, small spacing  2.54mm/0.1″ using,

but practically speaking, it could be any connectors that you define how they fit round the Mayfly 2×10 connector.

I have a PCB that fits on the analog side – for Electrical Conductivity  Stream Disconnect for (which I’m hoping to to write up pretty soon ) so it would look something like this..
