CH340 / CH330 for commercial crowdfunding product
(1/4) > >>
mohf:
Hi,

Many IC's can do USB to UART, not many IC's are under $1 at quantities starting 1k.

At just $0.3, the CH340 is extremely famous with Chinese Arduino clones.

What is your opinion on commercial products using CH340?

Edit: I'm mostly interested in driver compatibility and usage by n00bs / non-engineers.

Never had issues with them, although, not sure if they are even genuine. I have them on several devboards from aliexpress. There is also CP2104 popular, no problem whatsoever. But I'm not an advanced user, I didn't do any benchmarks, etc.

My USB<>serial of choice these days.

Had issues with others - mainly driver problems (some intentional, some not)

My first experience some years ago had me hunting around for a driver - but it wasn't too much of a chore.  Once found and installed, I had no problems whatsoever.

Finding a driver these days is a lot easier.

Plus it has the benefit of not having to wonder about FTDI hassles.  (That whole fiasco was a stupid move.)
madires:
I don't see any particular issue with that. Linux is a no-brainer (kernel provides the driver) and for Win/Mac I'd suggest to bundle the driver with the software.
