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.
Take care of a good power supply to the Pi and to that flasher device.
From my experience, it often fails if you simply use power from USB. Then I connect a real power supply directly to the small device and it all works.
