I theorize that you can replace the FFC cable with wires but you must keep the resistors on the other end. Ok it looks like the issue is from the thickness of the FFC cables, the connector on the FPGA side of the wiikey is different from the SD card slot side, the FPGA side looks to be a little cheaper and just doesn't like the other FFC. Re: WiiKey/Wasp Fusion SD card Slot Schematic and Wiring Please leave any questions or comments below. Here it is in action, you can see the repaired ground trace with the air wire. Remember a link to the SD card slot on digikey is hosted above.

Or you can just order them straight from the shared PCB way project.

I've updated the pcb files and you can download them here if you're interested here. Here's the updated board, it works great except I missed a disconnected ground trace on the connector. If you don't or lack any desoldering skills the parts can easily be found on digikey. (As I mentioned earlier both FFC connectors share the same footprint)ДЄll the other components are using the standard package sizes from the original board so if you have an original SD card adapter you can transfer the parts over. I don't have a part for the FFC connector as I just copied the footprint from the SD card boards. The footprint for the micro sd card slot uses this part from digikey: On the right hand side of the board you can see a second adapter for mounting and soldering a micro SD gecko board. Here's the front and back of the board that I'm currently having fabricated at OSHpark: It could also cause issues on the data lines with long game times so I'd recommend leaving them on.ДЄnd finally the reason for all this. I did discover that if there is no cable plugged into the wiikey it will error out so at least some of the parts or the FFC cable is necessary for proper operation. So overall the extra components are for filtering and protection. As for the 15k resistor on the clock line this is mostly likely a damping resistor for any ringing that would occur. Any comments you guys have would be appreciated. When high speed signals are sent over long wires (in our case the FFC cable) there tends to be some mirroring forming after long periods of time, so these resistors are there to filter and dampen the ringing. Your guess is as good as mine for the reason for this but the most probably reason is signal mirror filtering. Now if you do a little math you can see that most of the voltage is dropping of the 68.1k resistors and going straight to the data line.

Please note that the schematic that I have here has different names for each resistor due to the software that I used to create it, the values of the resistors, however, are clearly labeled on the schematic.ДЄs it turns out the wiikey/wasp does not use the SD card sense lines at all, they're completely disconnected, so any SD card presence sensing for the wiikey/wasp appears to be completely software based.ДЄt the top of the schematic we see two capacitors, a 10uf and a 1uf capacitor between power and gnd, this is just some simple decouple and noise filtering. Even the FFC connector has the same footprint size. So now after some tracing and double checking, both circuits are exactly the same. Here are the boards without any components:ДЄnd here's the wiikey SD card slot after removing the white solder mask: Here are the front of the wasp and wiikey fusion SD card slots, obviously nothing interesting here to see. Here are my findings: (pics are a bit big) The original SD card slot on the wiikey is a little big and the wasp fusion SD card slot is even bigger so it's not exactly ideal for a portable, so the best option is to replace it with a micro SD card slot. The purpose of this project is purely for portables.
