Build Notes
  • The plate + PCBA assembly is affixed together with screws. Please ensure these are removed before attempting to replace the plate.
search
  • The included sticker is an optional tape mod used to modify the keyboard’s sound profile. If you plan on swapping out your plates please ensure the plate+PCBA assembly screws are removed before applying the sticker to the back of the PCBA.
  • The Esc and Print keys are placed inside their own square cutouts. Some larger keycaps like MT3 will make it more difficult for keycap pullers to fit through the gap between the keycap and the cutout wall. Sometimes it might be easier to remove the top case before removing these keycaps.
  • There is a hardware reset button located on the PCBA underneath the Spacebar. On a short press the reset button will reset the keyboard - simulating the unplug / plug of a USB cable. On a long press the reset button will put the keyboard into the bootloader for flashing. 
search
  • To fully reset the keyboard including wiping the EEPROM (clears LED settings), please plug in the keyboard while the Esc key is held down. This is the Boot Magic button and will reset EEPROM and jump to the bootloader. You’ll need to replug the keyboard one more time or quick press the hardware reset button to start using your keyboard again.
  • The squishy pillars on the PCBA are for grounding. Please ensure your modifications do not interfere with the connection between the PCBA and bottom case.
search
  • The encoder knob is a tight fit on the encoder component to ensure they do not come apart during transport. One easy way to remove the encoder knob for customization is to push down on the Print and Delete keys with constant force while the bottom metal + diffuser assembly is removed. Make sure to have a good hold on your plate + PCBA assembly so as to not drop it inadvertently.

    I flashed via firmware into my keyboard, and is able to load and configure the keyboard on VIA. However, the changes made on VIA is not reflected on the keyboard itself. Any idea why this is the case?

    taptapzenWhich changes are you making in VIA and which version of VIA are you running? To confirm, does the keyboard keymap layout load in VIA and does the keyboard layout look correct in VIA (before any changes)?

    taptapzenI can't confirm. For me, everything worked fine except the LED speed changes. I ended up with VIAL firmware, and now I have my dream keyboard. :-)
