JMRI et Arduino / Re : Carte 24 entrées 48 sorties pour JMRI

Life got in the way of things for a while!
I received my set of test boards from JLCPCB, usual customary good service. The pitch spacing of the blocks doesn't match exactly with the original 24/48 boards. The block pin pitch is correct, just too big a gap between each of the eight way blocks. Not a huge problem of course but worth correcting if any one else wants to use the design.

Cheers! I had forgotten the pinout dimensions and got confused when I examined the pad layout. I have sent for a set of boards and will report back when I have assembled and tested them.

Again many thanks. Looks great. Do you have a part number / supplier for the switches you have used?

I'm currently making up a batch of 20 24/48 cards and it occurred to me that a LED test module with 24 LEDs in a row would be handy for checking all is working. Similarly an input test module with miniature switches. It is completely beyond me to design and produce the Gerbers myself. The 3.5mm pitch spacing makes it difficult to make anything reliable on 2.54mm board.

It goes without saying that this 24/48 card is extremely welcome and is a terrific job!
