First I would like to say thanks for making such a neat board, I really like it!

For a keyboard project I went to make 20 of these on JLCPCB with their PCB assembly service. I couldn't find the original crystal oscillator, so I had to change it to this.

When the boards came, I soldered the original Hirose connector on but I couldn't get my PC or Mac to detect it at all via USB. I thought perhaps I needed to burn a bootloader, but I'm having trouble using a Nano as an ISP to flash it.

Here is the board, the solder work by JLCPCB and the traces look great.

I was building my own controller using the latest release, but realised that I do not have the Hirose type CX70M usb-C connector. In my region, shipping of this kind of connector is quite expensive.

Hence, I am working on modifying the usb-C footprint to HRO 31-M-13, which can be purchased from aliexpress (see https://www.aliexpress.com/item/32998900371.html?spm=a2g0o.order_list.0.0.31b61802zlAvym for example). Will let you know how it goes.

Hi, sorry for opening an issue with a question, but could not find a better place to ask.

I'm an electronics newbie, so it might be a dumb question, but I cannot figure it out. Why are you using 4 x 0.1uF capacitors on VCC and 0.1uF and 4.7uF capacitors on VBUS?

When going through the datasheet for Atmega32u4 I've found that they recommend a 10uF on VBUS (so maybe you have smaller capacitance to improve reset time on reconneciton?). There's nothing about capacitors on VCC.

I've also checked ProMicro schematics, and they have a 1uF on VCC and VBUS connected together.

Sorry if it's a dumb question, but I'm looking into it for few hours already and cannot figure it out.

I'm relatively new to CAD and all this stuff, I decided I wanted to commission a PCB so I can handwire my keyboards. I've downloaded Gerber files before but I'm having trouble specifically with this project in which my Gerber files when I plot them on KiCAD. don't actually download as Gerber files and as some other type of file. With that said the PCB manufacturer can't support those types of files. If you can, can you either put a zip of the Gerber files or explain to me what happened? pretty please and thank you for creating this masterpiece of a microcontroller. I don't know if this is the right place to talk about this but sorry if it isn't

I wanted to contribute to Goldfish I designed a logo for Goldfish. If you like it, I'll send you all files.

Just letting you know that I snagged a copy of your schematic and used it as the base of a pin-compatible board, but with different design goals.

Right now my project is not an official fork of yours, but that should be fairly easy to do.

If you'd rather I changed the name of my project because it has different goals than yours, I'm more then willing to do that as well.

Of course, either way, full credit will be given.

Hi,

I'm interested in your design but would like to know how hard it would be to change the design to:
1, include an onboard voltage regulator
2, remove the USB-connector and add soldering points for +5 and GND in in addition to the data-lines

I'm not an electrical engineer and this might be a bit out of my league to do by myself.

Thanks in advance,
Rickard

I found this project via https://geekhack.org/index.php?topic=93571.0, while googling pro-micro with usb-c after breaking my usb port off and having to desolder and re-solder a replacement.

Any chance there will be a group buy or ability to acquire a prototype?
