Thanks. I wasn't aware about this project. For those that don't know, it is basically an open source Gotek derivative.

@DoG , or somebody else, any actual experience with this device? Any idea how much it costs to order a fully assembled board from Pcbway?

To be honest, I am little "surprised" that it is offered as "licensed", when it is based on a third party design. But that is non of my business, I guess.

I have one made by Simulant although it fried a USB stick and stopped working a while ago :D

Yes, It works like a Gotek. I don't have any problem with the two I built. I use mine with rotary encoder, buzzer and OLED display. I ordered blank PCB and soldering everything by hand and then programmed with serial/usb converter. I did not order fully assembled from PCBWay/JLCPCB so I don't know what that would cost.

Pin 46 is not connected on OpenFlops either.

I know, but it is coming in V2:

Oh, too bad and not too encouraging. Do you suspect it's an issue inherent to the OpenFlops design, or was more likely something specific to your unit?

To be honest I didn't investigate too much as I was keen to put a FDD back in anyway. I did update the firmware and try a new USB stick but that didn't fix anything.

It had worked well for quite a while and since nothing else changed I can only assume the drive itself failed.
