Good catch on that. I hadn't seen those pictures where it clearly shows a resistor there. The one I was going off of looked like a capacitor. From the one picture that's the clearest, it looks like a 2k-ohm +/- 5%, red-black-red-gold.

I'll update the schematic and PCB and upload the files later.

Yes you are right, in the other pictures it definitely looked like a capacitor.
Thanks for updating the files so quickly!

Yea I originally couldn't tell if that was a C or R, but it looked like a capacitor since I didn't see any color bands. I'm glad the additional pictures were found. 😜

In other news, there's a Ninjamicro Freespeed GFD on Ebay right now.. I may want to clone that one if someone buys it. Auction title: Abit KA7 KA7-100 Athalon Slot A Motherboard In the Box

I bought that board and also enough connectors and dip switches to make 25. I’m located stateside and looking for a project to do for winter.

I’ll upload high res scans of the Ninja micro when it gets delivered.

TBD plus shipping would likely be the target price once I check my stock of header pins and resistors . I may wait and order PCBs until we test some on them.

It's worth more if it works, if you can get a sample board to test it, could save a fair bit

You'll have to desolder the components, or measure with a multimeter, because there are several hidden traces on the Ninjamicro.

Please add my name to the list of those interested in this project, albeit with no assembly abilities myself.

@gbeirn

Nice catch! That board is probably the best Slot a board made. I used to have one.

In case it wasn't obvious, that board needs a recap.

This would be an understatement... I'm seeing A LOT of corrosion caused by capacitor electrolyte leakage (near the VRMs).

Parts came in today. Crazy fast shipping. Connectors fit just fine. Now waiting on the circuit boards.

Nice. I think my parts get here tomorrow. I have no idea when the PCB's will arrive.

Good to know that the connectors actually fit. That was my biggest concern, tbh.

I received my Digi-Key delivery today, too. Time between placing the order and having the parts delivered from Digi-Key in the US to my doorstep in Germany was less than 48 hours, I am impressed.
PCB production according to JLCPCB is currently at 54% and should be finished by Feb. 15th + a few days shipping from China.

My PCB's shipped from JLCPCB. I'll likely get them in a week or two since I chose the $3 shipping 🤣.

I did the FedEx expedited , the middle choice with cost I believe. We’ll see how long it takes. I’ve got to dig my slot A boards out of storage anyways

This project is great. I am looking for a gfd since a long time. It would be great to push my plutos. Thanks everybody for the great work.

@gex85: Hättest du noch einen über? Die Bestückung könnte ich auch selbst übernehmen. Ich würde mich sehr darüber freuen 😀.

@gex85: Do you have another one? I could do the assembly myself. I would be very happy about it 😀.

Abit motherboard arrived today. It is in one of the worst shapes I have seen with regards to capacitors.

Anyway, the promised pictures of the Nijamicro Freespeed along with the manual page ( nice addition). The board is simple, no extra hidden traces from what I can tell. I'll desolder the DIP switches and check at some point.

You'll have to check behind the SMD resistors as well, because a trace goes behind those and could go to either side or multiple resistors. The connector has a trace behind it too.

It would probably be easiest just to desolder the whole thing, document all components/values, scan the board on both sides, then put it back together.

@wiretap you are correct, I am working on that now. Hopefully in a day or two I’ll have some scans available.

In the mean time the SMD marked 221 are, predictably 220 ohm resistors. The ones marked 1200 are 120 ohm resistors .

9x 221 (one for LED)
8x 1200
2x diodes
1x LED
1x Molex connector ( DigiKey part number WM9132-ND
2x 8 Position SPST dip switch. (DigiKey part number 206-8ST) Same spacing as the other golden finger but 8 position instead of 10.

PCBs arrived today!

@t4ker: Since a few other people have ordered larger amounts of PCBs and parts as well, there should be enough to meet the first demand on both sides of the pond... Send me a PM and we work out the details!

Aaaand of course I immediately grabed my soldering iron and assembled the first one:

Now I have to get back to some "real" work but I will hopefully manage to give it a first try during lunch break.
Note that the resistor I used is 2.2kOhms because 2.1kOhms (as used in the original GFD v2) is a lot less common and 2.2 was what I could get at a reasonable price.

Looks like it went together and fits nicely. Fingers crossed that it works.
