Here is the public project: https://easyeda.com/diyman/expresscard-to-usb-3-0-miner-riser-egpu-adapter-public

And I attached the gerber files in .zip file too.

At jlcpcb.com/quote you can upload the gerber zip and order it.
Set the PCB Thickness to 0.8mm, and the PCB Qty to 5.

Instruction images:

Connect the pins
Tape down the WAKE# pin on the VGA

I have 9 of them left, I can send you some (I'm from Czech Republic). 😉

Hi @jero! Do you still have some of them in CZ? (I tried to send you a PM, but forum rejected it: You are not allowed to write a message yet.)

Hi @diyman! Could you please explain why is WAKE# pin on VGA card needed to be taped down? Also have you tested USB 2.0 socket on your PCB? According to EC port pinout, it is only USB 2.0 (and not 3.0) right?

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

@diyman Also what is the problem with pin which you highlighted on the last instruction image?

Hi,

So I've got the PCB ordered (finally) and I'm hopefully getting it in the next week.
The thing is I couldn't find any usb3.0 expresscard adapter. But as pali said, the pinout of the usb3.0 is the same as usb 2.0 in EC.

Furthermore, here in Algeria, USB 3.0 Expresscard adapters are basically rare, while USB 2.0 to Expresscard can be found.
Tried contacting stores and they said there might be some on the way in like 6 weeks.

Should I just go for a usb 2.0 to expresscard adapter (and probably use a female USB 3.0 from some available cheap products) or?

Wikipedia says Express Card 2.0's USB 3.0 connection uses pins that are for PCIe so you can't do USB 3.0 and PCIe at the same time. The Bplus PE3A also explains this. Therefore, you should stick with just PCIe + USB 2.0.

I guess you want ExpressCard 2.0 anyway, to ensure support for PCIe 2.0 speed of 5 GT/s but I don't see anything that says earlier ExpressCard couldn't support 5 GT/s.

The ExpressCard 2.0 spec can be downloaded from http://www.usb.org/developers/expresscard/EC_specifications using the wayback machine web archive (Oct 2016).

Edit: I realize that you might not care about USB 3.0 functionality and just want the ExpressCard 2.0 adapters just for their connectors? Do you need a specific brand or model of ExpressCard adapter? Amazon has many - don't they ship to Algeria?

Question: I see the PCB for ExpressCard/34 only has PCIe. Is there a reason why it couldn't also expose a USB 2.0 connection like the PCB for ExpressCard/54 seems to? And can USB 2.0 and PCIe x1 be used at the same time?

Hi, I just realized the reply and I appreciate it. Also sorry for not reading it earlier as I already bought an Ethernet Expresscard that will come in handy later.

No, I wasn't really looking for specific models.

That said, the latter is a working 34mm ExpressCard 1.0 (not 2.0, also my laptop is only capable of 1.0), I also have a PCIe x1 - USB 3.0 that came with the Riser-006c, and both the 54mm/32mm PCBs that diyman shared before. Pretty much everything I need for my DIY adapter.

The question is if I should pick the 34mm PCB and solder stuff to it, then I have "the metal shields/plates" that cover the ExpressCard to, well.. cover it, or I should pick the 54mm PCB and have no shield to it (just placed as is with the soldered stuff in the Expresscard slot), and if there is any bandwidth differencies for both of them.

As for the 34mm Expresscard, I don't see why it wouldn't have a USB 2.0 connection, they're the same slot wise except for the size.

Edit: Actually, I will leave soldering components to a local store, they said they can do it for me.

I believe there exists places where you can buy the Express Card connectors separately. There are places that sold the Express Card shields and plates but they have no stock now and probably won't get new stock.

I think any bandwidth differences would be caused by transmission errors which shouldn't occur if the quality is good enough.

Like I mentionned, I already have everything I need. The local store said that they can do all of the hardwork for me.

The PCBs I have came in a good quality, so transmission errors shouldn't be a thing.

I will be probably picking it the next wednesday, so lets hope my HP Pavilion DV7-3160 will take my GTX 1050 for a ride.

It's worth mentionning that I have a low profile 300w psu, that should come in handy when I make a portable case for it, I might even post in the builds section if it works out as it should.

Model? I keep a database of psu form factors and their sizes.
