- Get lead free, or better, gold, plating.
- Confirm you have all bill of materials
- Cut 128 pieces of foam. (64x2)
- Do the key caps (64):
- Open it up.
- Tape the sides.
- Glue the foam.
- Lube it up.
- Close it up.
- Do the soldering
- Solder the diodes.
- Solder the reset switch.
- Solder the brackets.
- Solder MCU on the bracket.
- Electrical tape on top of MCU to separate it from OLED.
- Get 2 spacers.
- Get an acrylic shape that will cover the OLED and fit the board.
- Glue 2 spacers to the board.
- Screw in the acrylic cover.
- Push to github.
- Wait for Github actions
- Download the UF2 file.
- Plug in the keyboard via USB-C.
- Double click the reset button on the keyboard.
- Drag the UF2 file onto the keyboard.
- Done!
Only the left side needs to be flashed if you're only changing the keymap.

Sections:
- Split keyboard halves unable to pair
- Do I test it without soldering before I solder? Does that even work?
- How do I do it?
- How do I put the OLED on top of the MCU?
- Double check: Do I need to worry about:
- TRRS
- P1,P2, R1, R2.
- GND, LED, VCC
- Do I need a power button? Why not?
- Yes, I do need a power button. Can I add it later? Use it wired for now? I think yes.
- Does the power button go where the LED is currently? Will it work if I don't have a power button?
- Theoretically, it might work off USB C but then not work with battery.
- Will 110 mAh battery be large enough?
- Finish the build instructions
- Finish the zmk_config repo
- Specifically,
- Specifically, need to move the keymap to the new repo.
- Specifically,
Lay out the PCBs so that there’s a left half and a right half. The columns of holes with a white border around it are where you put the pins if you’re putting the controller in with components facing down, the other two columns are what I ended up using for the nano with components facing up
Put components facing down if in the white lines, facing up if NOT in white lines.
- Built in m2 screw holes to cover the OLED.
- Add to build list
- 4 screws
- acrylic cover.
- Add to build list
- You can move the thumb clusters a mm or two closer.
Two options.
- Github actions
- checkout zmk alongside zmk-config, and then use -s to point to the zmk/app folder, while running it from the zmk_config folder? Correct, that should work OK. I am pretty sure you need to provide the config location to the command so there isn’t much benefit to being in the config folder. I always build from zmk/app while pointing to the config folder with its full path, to pick up the keymap from there
- Double tap reset button.
- Device shows up as USB storage.
- Drag uf2 onto USB storage device.
