Hey man, first of all, huge thanks for putting this out here! It's been a big help to me in working on my own keyboard PCB design. However, I had a few questions about the components you're using for this project and was hoping you could help me out.

First of all, if I understand correctly, the "ISP" pins (J3 and J6 in the schematic) are used to flash a chip without a bootloader. However, I can't see anywhere what type of ISP and what type of connector is actually used to connect to this. Is it just a generic ISP programmer and the pins are soldered to? Or is there an actual connector that can be used for this?

The second thing is the parts D27 and D28. Your BOM only annotates these with "red" - does this mean any red LED will do here? I assume that this is just to indicate power to the PCB, is that correct?

My last question is about the parts P3 and P6. These have the annotation "WS2812", but they do not appear on the BOM. They are hooked into the same circuit the LEDs and the name fits too, so I assume these are LEDs too, but they don't fit the footprint of a WS2812 and don't have enough pins. What are these meant to be used for?

Thanks in advance for any answers you can give me. I'd gladly make a PR with more annotations to these parts if you tell me about them, so that's it's easier to get a hold of all components needed to build this board for other people too.

Hello awesome project products. I have been ordering parts from novel keys.

Does this board support Kailh low profile sockets?
