Overview
KiCad project for creating a extender card. The extender card is useful for working on a Korg PS-Series Polyphonic Synthesizer.
The card is a pass-through board that extends a card outside the Korg synth chassis, to enable easier access while diagnosing and repairing
The extender card plugs-in to Korg synth backplane, and provides 2 44-pin card socket connections to host the Korg KLM board.
Parts
Card-Edge Sockets
Sockets can be:
- Sullins EBM22DREH
- EDAC 305-044-520-202
- Vector R644
- or similar card sockets.
Test Points
The card provides header pads for adding test points.
The test points are:
- Molex 0.156” (3.96mm) header format, using vertical headers
- Molex KK396 part #0026481240
Card Dimensions
- Dimensioning of card assumes landscape orientation
- Height: 228mm (including edge-connector).
- Width: 240mm
- Edge connector pads mirror card-edge traces, but there can be some variance in edge connector sizing & placing
- Edge connectors can be between 87.5mm & 89mm in width and 10mm in height.
- Edge connectors can be from 14mm to 15.5mm from outer (left/right) card edge.
- Edge connectors can have a 32.5mm to 34mm gap between them.

Questions
How big is the Card extender PCB?
It measures 240 × 227 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Card extender use?
15 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Card extender KiCad files?
From the ddkaiser/pscards repository on GitHub, at the commit this page was made from: the board is card-extender/card-extender.kicad_pcb and its schematic card-extender/card-extender.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Card extender design in my own project?
Its repository states no licence, so its author keeps all rights: ask ddkaiser before reusing the design.
