Hi all,
I decided to do a seperate PCB. I don't like the USB-HUB idea for three reasons:
1. there were already problems with counterfeit ICs
2. USB dongle-li-di blah blah (too much connector cables)
3. I am in the need for a specialized HUB ICs and have no clue about its availability / obsolesence plan
So let's just take two Picos. Why? Prices for a Pico are a joke, especially the needed RP2040. And even if you go the HUB-IC route; this is an IC, too. Ok you can get those ICs for 1 dollar / euro.. But if I socket my Picos I can do way more with them, since they are not specialized and can be re-programmed.
Another benefit is, that there is no cable salat anymore
There is only one downside (if one cares) and that is space. For me this isn't a problem. For me this approach is far superior to the PicoMite USB variants. If one types fast, there is no option around it, I think - unless Peter could speed up things. But I guess there are limits. I have no clue about this...
A HUGE benefit is also, that there is no need for a USB variant anymore, you can even use USB and PS/2 "at the same time" - I mean without re-flashing the firmware - how cool is that?!
If there is interest I will publish the gerbers, for now I have to get them made for me, if they arrive I will report back if everything works fine.
"CON1" on my PCB is only for measurements / optional...
Greetings
Daniel
