Sofle RGB V3 Hotswap Split Ergo 50% Keyboard Kit

Designed by Dane Evans based on the original Sofle Keyboard by Josef Adamcik (GitHub repository). Build guide here (does not mention the power switches that are mounted on the top of the PCB on each side).

Modified by 42. Keebs with larger pinky stagger (same as on Sofle V2), power switches and a battery contacts. Version 3.2 adds native support for the nice!view (separate 5-pin footprint just below the OLED one).

Build your very own split custom keyboard from scratch!

  • Split 12×4 + 10 (50%-ish) ortho/ergo layout
  • Uses Kailh hotswap sockets for Cherry MX-compatible switches
  • Supports 2x EC11 rotary encoders, one in each half
  • Supports optional OLED screens or nice!view LCD screens natively (new in V3.2)
  • Quite easy to build – based on Pro Micro controllers. Uses SMD diodes though.
  • Includes FR4 switch plates and acrylic bottom plates
  • Optional acrylic or foam upper/lower mid layers available for a case without any gaps
  • Tinned lead-free finish, black solder mask

Case options:

  • Minimal version: Just a switch plate (FR4 or acrylic), PCB and acrylic bottom plate (with brass standoffs between the switch plates and bottom plates and screws from both sides)
  • With upper mid layer (acrylic or foam) to fill the gap between the switch plate and PCB
  • With lower mid layer (acrylic or foam) to fill the gap between the PCB and bottom plate
  • Full case with both upper and lower mid layers for best look and feel with no gaps! Uses threaded heat-set inserts in the bottom plates and longer screws from the top only.

⚠️ Please note, there is a bug in the wiring of the in-switch RGB lighting. As is, EITHER the underglow, OR the in-switch lighting can be used, not both at the same time (without a fairly simple jump-wire modification). Documentation coming soon.

Firmware will be available from the Firmware page soon. If you want to build your own firmware, you can use the standard Sofle firmware – in case you want to use RGB lighting, you need to change the WS2812_DI_PIN QMK setting in config.h to D4 (as the original pin was required for the nice!view support).

Kit includes:

  • 2x main PCBs
  • 2x FR4 or acrylic switch plates
  • 2x 3 mm acrylic bottom plates
  • Optional upper and/or lower mid plates (foam, acrylic or plywood)
  • 62x SMD diodes
  • 2x TRRS sockets
  • 2x SMD power switches
  • 2x reset switches
  • 58x Kailh MX hotswap sockets
  • Mounting hardware (brass standoffs and/or stainless steel screws)
  • 2x acrylic covers in a matching colour where applicable, or in clear acrylic

Parts required to finish build not included in the kit:

  • 2x nice!nanos / Froods / Pro Micros / Elite-Cs or compatible controllers
  • 58x Cherry MX-compatible switches

Optional add-ons available but not included in kit:

Please note, controllers and screens displayed in the product photos are not included, but they’re available as add-ons.
