A friend of mine made a board to upgrade the uConsole, expanding the GPIO and unused USB with i2c headers and a USB2 hub.

It connects to the 40-pin, 0.5mm pitch GPIO FFC/FPC connector, as well as being soldered to the unallocated USB4 pads. It splits out 3.3V I2C, providing a Qwiic connector (JST-SH) and soldering headers, and also provides a GL850-based USB2 Hub, the 4 ports accessible by soldering headers.

So, I guess I finally should make the #introduction post -- no, really. Especially, today is the last day of my current vacation, so now or never.

[If you can speak German 🇩🇪 with me, please do this - I had no chance to learn the language in my family because of damned #soviet #communist rule and its nationalistic repressions, but I really intend to combat this issue.]

Meh. What's the #impedance of a #RaspberryPi #GPIO pin in input mode? Is it safe for a high value from another pin in output mode to sink directly to it?

I haven't found this discussed anywhere. It 𝘭𝘰𝘰𝘬𝘴 as though a pin in input mode has quite a high 𝑍 and sinks very little current, but I don't want to experiment just in case that's an invalid conclusion. 😔🤔

@neauoire What does one need to DIY core memory weave and have it addressable by smolputer #GPIO with #I2C or whatever? Just hook it to usb and zap at it? Any notions offhand?

This is to say I have some notion of how to make the core weave from junk, but little grok of a platform which can talk to it readily.
