Ordered the missing components because i needed some mosfets anyways. luckily i took notes before i abanded the project a few months ago.  :thumb:

Just got back to this thread after almost two years, because Elite-C expensive... :) I also found the alternative connector at LCSC, it's great that you confirmed that it works correctly. I'm a bit uneasy about the low stock (only 35 atm) - hope it's not discontinued. I want to see how much will LSCPCB assembly cost, I would eventually like to order ~50-100 for my little on-line shop I started in December. I offer good value through-hole kits and also Pro Micro based kits, so having a cheaper controller module with USB-C would be great.

Do you have a BOM at LCSC? I'll be watching with interest, hope you can finish your boards and confirm they work correctly :)

Thanks!

I'll happily share the exact parts I ordered once can confirm them working :)

If you (or anyone else) put together a BOM/other resources let me know and I'll add them to the first post and the readme on Github.

Let me know when you start selling them, I'll add a link to your store too.

Had some done via PCB A , still had to solder the USB Connector by hand though :(
Works very nicely

Where can I buy your version?
is it https://shop.beekeeb.com/product/goldfish-rev-c-open-source-pro-micro-replacement/ or https://shop.tokas.co.uk/product/comet-usb-c-microcontroller ?

Tokas is selling boards at that second link. It's a modified design with a different USB-C connector.

I had no idea beekeeb is selling goldfish too ;D I have added links to both vendors to the original post and the Github repo.

Everyone, LMK if there are any other Goldfish or derivations for sale that I've missed and I'll add them too

I can add some TVS diodes if transients do end up being a problem, but I doubt it's needed.


Is a TVS diode used for ESD protection?

What's the use of the R6 10k resistor?

It pulls down VBUS and the UVCC pin when the board is powered by the VCC pin, not through the USB port.
