Sourcing a CH341A

How'd that AliExpress chip work for you?

Didn’t get around to trying it yet. I’ll see how it goes sometime after this semester ends.

The first two prototypes were built using ICs from AliExpress.

Another option, if you have a hot air tool and the ability, is to remove the CH341A from a working USB EEPROM programmer. These are available for less than $10 from Amazon, and you can confirm that it's functional before removing it from the module.

I've been meaning to ask that. Can you recommend a hot air tool? I imagine conventional hair-dryers probably put out enough static to fry the chips.

I use a little 858D hot air tool. You can get em on Amazon for $50 or less.

I mostly use it for degooping and heat shrink tubing, but it works great for reworking SMD components.
