Eurocard DIN41612 3U riser extender PCB card 220mm with test points and PCB guide
Introduction
I have originally designed this riaser card for few of my projects, but this turn out so well that I have now posted all schematic, gerber files and documentation to fellow enthusiast such as yourself :) Perhaps (and I hope) content in this obscured corner of interwebs will inspire you to start your own projects.
Eurocards system in general is enormously versatile for all kinds of projects thanks to standardized mechanical dimensions and quality connectors. You can literally make any project and skale it up as much as you wish. For example this extender card can be used as exnteder card as the name suggest doh..., but also to intercept and trouble shoot signals and as a prototyping platform if you attach solderless breadboard to it.
You can use these cards in industry standard DIN subrack or Eurorack.
Card will fit nicely in PCB guide rails. Card also contains 3x32pin rows for test points and 3x32pin rows for 0.1" Dupont header connectors.
Card has been designed to be very versatile and you can fit 96 and 64 pin DIN connectors each side if you wish or 64pin female edge connector.
Quite recently I have figured out, that card can also be used for prototyping if you don't install red PCB rais and fit female header in test point area. Stick breadboard directly on card and voala :)
These boards look absolutely gorgeous in standard green solder mask if you going for that standard industrial look. I can advise you where to buy connectors, however you can use any standard 96/64pin DIN Eurocard connectors or 2x32, 64pin PCB edge connectors.
PCB support guide rails for extender card look best in RED colour (Violet color would also be nice). You have to assemble them yourself.

... but if you feel like getting something for nothing isn't your cup of tea (completely understandable) (ಥ﹏ಥ) and a prefer to support me and get something back in return, then you can purchase directly on my eBay or Tindie shop. However if you are still up for an adventure */in very positive way/* (and are happy to have PCB's made yourself in your favourite PCB house - PCBWay is highly recommended), then carry on, download gerber files and have fun!

Assembly instructions and notes
■ Gerber files contain " JLCJLCJLCJLC" to silk layer. You can specify a location of the order number, select the "Specify a location" option when you place an order. Only if you order via JLCPCB
.
■ Fit Female and Male DIN 41612 96pin 3x32pin right angle connector or alternatives you wish to use
■ Use M2.5 screws and nuts to hold DIN connectors in place, thse don't need to be fitted to achieve strong mechanical connection however
■ Use a temperature-controlled soldering station and quality solder. Take care not to leave solder bridges as any short circuit will most likely lead to failures
■ To assemble rails: You have two big side PCBs and one middle as sandwich. All you have to do is to cut them out, smooth out mouse bite edges with sand paper and then bolt using M2.5 - M3.0 screws and nuts (or equivalent values in Imperial) or glue them together. You can buy test points on eBay (search for William Hughes PCB test points). Pictures are pretty much self explanatory, but please let me know if you need help with it.
■ Fit 2x 800 point solderless breadboards if you wish to use cards for prototyping
