Reliable source for CH341A USB controller chip?
« on: Yesterday at 12:46:42 PM »
I want to build me one of pedalpcb's "DevBoards" (https://www.pedalpcb.com/product/fv1dev/) for the FV-1. I have Spinsemi's dev board, but it's a bit of a drag to always swap out the EEPROM from the actual stompbox to load it on the dev board then plug it back in again. A lot of work if I just change a line of code and wanna check out if it works ... with the DEVBoard stompbox I just re-up the code directly to the pedal and can test it immediately.

So I ordered a couple of the PCBs, I have a handful of FV-1s, but sadly the USB chip itself, a CH341A seems to be in very short supply, there's only a shit ton of already soldered ones in varying packages. And I anhor desoldering such a tiny thing.

Now I went against my principles and ordered a couple @ Alibaba, but this is not my idea of a serious source. It may well be and I may well do someone injustice, but there you go ...

RS Components, Mouser, Big C, all the usual suspects don't have this one listed.

I also can't seem to Google up direct replacements.

Any idea how to get some of those CH341As?

Following because I'm also interested. I built one of their dev boards a while back when they have the CH341A in stock so they included one, but I'd love to get some more for other experiments.

Quick update, I looked around a bit more and it looks like CH341A is exclusively a Chinese chip, which explains why typical reputable suppliers don't carry them. I found some on Aliexpress and ordered 10 for $12.70 total shipped. ETA is about 3 weeks, but we'll see what happens.
