It’s breadboard with an extender for a Raspberry Pi’s pins flipped upside down, a Raspberry Pi Pico, jumper wires, and a clip that came with a CH341A that suffers from the issue of being 5V.
The issue I think would be length of the wires.
Any thoughts? I’d consider soldering something together but I don’t have a soldering iron that would be great for something so small and I’m working with what I have on hand.
I also have a Raspberry Pi 4 and the CH341A that has the voltage issue if anyone has a better idea that might work.
My thoughts are you should just try it. If the wire length is your biggest concern just try to minimize the distance between everything as much as possible. I assume the thinkpad can be positioned closer.
I’m guessing it’s either an issue with the latency or internal resistance of the wires (as someone else mentioned) so unless I’m cutting and splicing the wires I don’t think that will matter
The length of the wire is actually more an issue of capacitance and interferences. But these issues are easily mitigated by reducing the spi speed
