FAQ
Q: What key switches are recommended?
A: Cherry MX RGB switches are recommended and are linked in the BOM. Different varieties are available (Red, Brown, etc.)
Q: Can I use other keyswitches?
A: Yes - as long as they have the same footprint as Cherry MX switches and a window/opening for the LED to shine through. Low profile keys like the Cherry Low Profile or Kailh Choc switches have a different footprint and will not work.
Q: What about recommended Keycaps?
A: Also listed in the BOM. You want an MX stem cap, with translucency or a window for the LED to shine through. DSA profile caps work well.
Q: Does this project require soldering?
A: Yes. Thru-hole soldering is required along with some easy SMD (LEDs and jacks).
Q: What's with these LEDs?
A: This project uses SK6812-MINI-E reverse mount LEDs. They are somewhat hard to find, so I'll try to offer them included with kits. They are easy to solder, even if you've not done much SMD.
Q: Can I get the Gerbers or order the pcbs myself?
A: No. Not sure about open sourcing yet.
Q: Can I get some of those windowed keycaps you're using?
A: Yes.
