Haha. In fairness, he can’t know demand for his add-on boards until the first batch. But given the reaction, I’d say he has a solid winner here.

I have a 3D Printer, Bambu Lab P1S, I can help printing it. US, Utah here.
Okay, see, this is a different thing entirely. Bro, you can literally have multiple expansion cards hanging off of the left side now. A joystick and back buttons, the LTE module only uses USB IIRC, you can throw a LoraWAN compatible module on there… an SDR even.
I salute you as formally as I can in a comment section dude.
Here is a CircuitPython demo!

Awesome! 
I just published prerelease of uPico control application: Release MVP · dotcypress/upico · GitHub
Application tested only on R-01, cause I’m still waiting for CM4 adapter.
Any questions/feedback are welcome!

Did the uHub go on sale? Did I miss the mark yet again!? 
It was on sale for half of a day.
Next batch already in production

awesome work! will probably get the gpio version. would like to see a teensy 4.1 in this form factor for m8 headless, might have to puzzle it out myself.

Ive been looking into trying to link up the pi4 and the teensy gpio pins together for this exact reason but im still pretty novice on this subject.
Update: looks like there is a way by using the UART pins (tx,rx) on both boards to send/recieve data and then do some hocus pocus coding on both the teensy and pi to accept data coming through that way… but i cant know untill i get my hands on both and this expansion board listed here and start to figure out programming myself…unless anyone else wants to try
uPico back in stock

Probably still a year out from my uconsole showing up, but might as well buy one of these now – just in case.

Just got both the uPico and uHub in the mail last night. Will try to scrape some time to do some testing on them in the next few days.

Sorry to hear that, let’s try to find a root cause.
Could you try lsusb and post program output?
Also it will be helpful to get a photo of uHub on chip side, maybe something go off during shipping.
I created Discord server for support/questions, everyone are welcome Quadbit

This looks amazing. Not to sound stupid or anything but this is an expansion board that is essentially a Raspberry Pi Pico in another format? Also I notice on the Tindie store that there’s no shipping rates to the UK but I can email to ask. Are you shipping worldwide?
I tried another peripheral with an indicator LED and verified that the ports do work; I think the original one I tried (Sandisk Extreme Portable SSD) just drew too much power. That’s on me for not doing my due diligence.
Yes, by default, current maximum is 500mA per port.
But you can easily update that by changing values of R9, R10, R13.
