Too kind, as always. Thanks for sharing your expertise. I've removed the uart interface, will add a ws2812b status led, and added an automotive 2A input supply from MPS (supporting 9~60vdc). That should work with my 24v and 48v PSUs. For the remaining bits you've advised, I'm eager to simply add bidirection translation for the 50 gpios and send that out "as-is" rather. Reason for this is; I want to test ALL gpios on that unknown-to-me fpga before sending out a final board version. Would that be a fair approach?
Tiny motion control board, although likely to pack an incredible power (thanks to the Rio Cult!!). Still plenty real-estate for the translation and other upcoming gizmos.

True. Let's hope that badboy will be fit for a 4ax mill, 2ax lathe and ofc a 3ax co2 retrofit (<- my first project). Nice connector link up btw, I use the same although in a 2.54mm pitch.it always depends on the application,

Reference routing (inspiration) for the above wiz part schematic. I doubt all that analog/digital isolation insanity is mandatory, but some does claim those motion control being noisy [rolleyes], and so best practice always just add them in if you are routing this. All what's left to do is the 3V3~5V translation and hooking up 50 gpios. Tomorrow. Maybe.
My Riocore Kit looks forward its own faraday cage (EMP warfare protection [rolleyes x2[). Let's get in touch, Olivier - I'll send you one (or two!).

wow, that looks really professional, you can tell it's not the first time you've done it.
I wouldn't know what to say about it either, you're doing really well!

Looking good guys.
Set up a forum member yesterday with my Spartan6 hardware and a basic riocore config.

ahh, I just saw that Mecanix has 'riocore' on the case
maybe you should think again about the naming !?!?!
originally it was called LinuxCNC-RIO, where RIO stands for Realtime-Input-Output.
riocore was only the name for the repostitory, as I had initially separated it into core and gui for the rewrite (because of the dependencies), but this is now all in riocore.
Does anyone have a better name?

F'ing Awesome.
But I'm an uncouth Aussie.

2. RIO
3. RIOCORE
4. Really Important OS
The enclosure was spontaneous and meant to illustrate the end goal for the protruded 90deg connectors. Just sketched a rectangle with 4 tabs, extruded it, cut off around the solids and branded it RIOCORE without thinking half-a-second (<-- birth defect). Really did took 3min from start to screenshot. ps. I'll admit I kinda like this RIOCORE though... sounds hardcore as it is!

your case just reminded me again that the name should also be fixed at some point
lsf0108pwr looks good, I have to remember it
but at the moment i don't know what exactly it's for, opto inputs don't need it and for step/dir outputs it might be too weak.
PMOD is usually 3.3V
maybe for some universal IO's
