It's a 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.
Then why don't you?
Just don't do this to your only main device
Because it can be very finicky and I don't know what the ramifications would be if the wire length did cause issues flashing the firmware.
I would follow the installation steps and make a backup and check that back up but I don't know how badly errors during the flashing process would effect the laptop.
Plenty of people also seem to use the CH341A unmodified without issue but I don't know if the 5V issue may cause problems in rare situations or if it's a complete gamble of whether or not it could brick your device. If it's only an issue if you do something like jostle the clip while it's doing something than it would be a lot easier for me to just go that route
Chances are it is fine. I don't believe the flasher goes terribly fast. Also isn't there some sort of checksumming? I've never owned one of these devices but they are pretty popular so chances are if there was a serious danger a quick search would show it
+1 it'll be fine
You only need to worry about wire length and ringing when you're talking radio or modern CPU or graphics cards speeds. Anything pi related will be fine
