E80-1800 VS crkbd

Depends a lot. If you want it fully assembled, you have to go to larger fab houses like PCBway, and spend a few hundred bucks on a 5pc batch. If you can hand-solder some parts (in this case, the Bluetooth module and the USB connector) and design the rest around jlcpcbs libraries, you can get away with 20-30USD per unit (MOQ of 5) plus shipping/customs. Then add another 10USD for the bluetooth module and USB connector.

A simpler wired design like my E80-1800 (https://github.com/ebastler/E80-1800) can be completely assembled by jlc for ~30ish USD per unit.

Oddly enough, small-batch prototyping at jlc can be cheaper than medium sized (50-150 pc) runs at other fabs.

Hope this doesn't sound like an ad, I've compared a lot of prices and nobody came close to jlcpcb, but With their limitations (limited stock, limited finish/color choices, frequently chnaging stocks and component prices) and sometimes far-from-ideal QC (some scratches can happen, in rare cases even missing components that were present in the BOM) they are not really my first choice for production runs. For prototypes or small unofficial-ish batches with a few friends though - god tier.

Some options include but are not limited to TKC1800 PCB, E80-1800 PCB, GH80-3000 or 3003 PCB.

Looks at the order here : https://github.com/foostan/crkbd/issues/96

I followed this guide for the build (https://github.com/foostan/crkbd/blob/main/corne-classic/doc/buildguide_en.md)

Not sure which information you mean, but here goes. Nice!Nano v2 Pinout (shows Arduino pin mapping). Nice!View Getting Started (explains how to remap the CS pin for a non-native shield like Corne). The overlay file where "cs-gpios" is set for the nice_view_adapter in ZMK. If you look at the Corne Schematic, you'll see as shown in the labels in this image that the bottom two pins (B2, B4, B5, B6) don't appear to be used for a column, row, or the OLED header. But the only way to really verify is to pull the KiCAD file for your Corne version and check yourself. I think D0 ("Data") should work. It appears to go to an optional I2C connection.

Want to say the corne board drawings etc are available at https://github.com/foostan/crkbd as well, if you fancy learning kicad you might be able to tweak them yourself ... though that is definitely the deep end of things...

For the layout, I took inspiration from the CRKBD and the Boardsource's Microdox.

This is the numbered LED series from the Corne Classic Build Guide (https://github.com/foostan/crkbd/blob/main/corne-classic/doc/buildguide_en.md)

I would need hex file from here https://github.com/foostan/crkbd/blob/main/doc/firmware_en.md and then i need to run flash command . Il read through it one more time, it seems that i use same hex file for both sides.
