Put me down for package - I've been thinking about driving a handful of relays for various things, and have been thinking about having a small number of boards like this done - it's pretty much impossible to find a generic prototype board with 2mm pitch holes... Although I'm no designer.... - What about extending the 12V rail all the way to the end of column 16, parallel to the ground rail? - Currently, all the holes are isolated. Would there be any benefit to connecting the holes in each row in groups of 3 or 4? Brian. On Wed., Apr. 17, 2019, 19:37 Mark Webb-Johnson, <mark@webb-johnson.net> wrote:
It seems the attachments were messed up, so attaching again…

Design layout. Looks good to me, but open to suggestions...
We can make in sets of three PCBs, to keep prices down.

A kit of 5 PCBs + SIP edge connectors + mounting hardware, unsoldered, would be about US$15 + shipping. About US$3/board set. With shipping I don’t think this is worth doing with less than 3 or 5 boards per kit.
Would this be useful?

This is the closest we have today:

That is a bare modem board, with just the sip connectors. The prototype above is a K-line transceiver.
I think it would be trivial, and cheap, to make up what you show. Perhaps just solder ready pads at 0.1” pitch, then the side sip connectors wired to the first row of pads at each edge. Perhaps 5 PCBs in a kit, with sip edge connectors, unsoldered, in a simple plastic bag.
Does that sound like something useful? If so, I can ask the China guys for some idea of pricing. If it is just the unsoldered pcbs + parts, I don’t think it will be expensive.

Mark,
do you know of some kind of prototyping board available that fits to our piggy back expansion layout?
Something like this: https://www.robotshop.com/de/de/cytron-arduino-proto-schild.html

If you have work to do on this DA26 expansion ports, this is pretty cool and well built:
