10u revxlp prototype build in c/ergomechkeyboards@lemmy.world

Do remember that even with assembly on the bottom, you still need to solder the controller sockets, pogos, and battery connector.

Yes. The PCB and pick and place files all look good. Does seem that JLC now doesn't have the threaded solder nuts in 2mm height for some reason, so you'd need to source those along w/ the hotswap socket, and any other parts they get grumpy about.

Sorry about that. Fixed!

Let me double check the PCBA files... I didn't get the 10u protos assembled, but they should be fine.

10 work has been merged. I've got a bit more docs work to do on the new optional bottom facing single color LEDs, I would skip those for now.

I'll post my personal keymap a bit later. It's mostly Callum style mod approach.

It's in a branch of the repo until I can address one or two minor issues, and some docs additions needed.

Indeed! It was somewhat inevitable it was going to, but I still wanted to do it for the XIAO-ness of it.

10u revxlp prototype build (lemmy.world)
 

Been iterating a bit on my revxlp design, and a frequent request is for a 10u/"5 col" version.

Finally did a build of the first protos, and it's working great! I want to do a few tweaks for the newly added ability to use the single color LEDs for either per -key or bottom backlighting, once that's done I'll formally release the changes.

This particular build was half soldered by our elder daughter, and she fully assembled post-soldering including keycap selection. I love the look she chose, which she said "reminded her of a sunset over the water"

  • 10u revxlp
  • XIAO RP2040 running ZMK
  • Keycaps:
    • MBK: dyes from MKU and factory dyes from LowProKB
    • Asymplex convex 1u artisans for the bottom row
  • Choc whites
  • MJF nylon case print from JLC

revxlp - low profile, unibody split for XIAO family of controllers (lemmy.world)
 

Reposting to this new community!

The revxlp design is a refactor of the revlp PCB by Cyril that:

  • Uses XIAO footprint controllers, many wired options like XIAO RP2040 or wireless with the XIAO BLE.
  • Adds 2x1u middle thumb option, retains 1x2u support there as well.
  • Includes a 3dp shelf case option, using solder nuts for assembly to retain clean top plate with no screw heads visible.

revxlp is OSH, repo at https://gitlab.com/lpgalaxy/revxlp

This particular build in the pic is:

  • Choc sunsets
  • MCC keycaps
  • Funky rp2040 + mini OLED that's close enough to a XIAO footprint to be compatible.
