The Aurora Helix is a redesign by of the popular Helix keyboard by Makoto Kurauchi. The original project is open source. For every kit sold, will donate €1 across the firmware projects we support.

What's the Aurora Helix?

The Aurora Helix is an ortholinear split keyboard with up to 64 keys and (up to) 2 encoders. With its number row, it's a comfortable introduction into split keyboards for those who'd prefer to not dive deep into layers straight away, or those who use numbers very frequently. It can also function as a macropad with plenty of keys, as it's possible to use a half on its own.


The Aurora Helix supports the following features:

  • A comfortable layout with 64 keys, optionally removing the bottom row, making it either a 6x5 or 6x4 layout with one or two additional thumb keys;
  • Powered by QMK or ZMK firmware;
  • Support for MX (see remarks) or Kailh Choc (v1 sold at, not v2) switches;
  • MX spacing for all variants;
  • Top mounted controllers for a lower profile;
  • Up to two 128×32 pixel OLED displays;
  • Up to one EC11 rotary encoder per half;
  • Per-key RGB backlight by individual RGB LEDs;
  • Underglow by individual RGB LEDs;
  • Support for a power switch for wireless controllers;
  • Support for the tenting puck.

What's included?

Every kit includes:

  • 1 × Left PCB;
  • 1 × Right PCB;
  • 70 × 1N4148 axial signal diode;
  • 7 × 4k7 Ohm axial resistor;
  • 2 × PJ-3200B-4A TRRS Jack, black, and;
  • 2 × Reset button.

The Choc Hotswap kit includes SMD diodes and SMD resistors instead of axial ones.

If you get a hot swap kit, the kit will also include:

  • 64 × Kailh Hotswap socket in either Choc or MX, black.

What's required?

Beyond the kit contents, you'll also need to get the following items to make a working keyboard:

If you're getting the hand solder kit and are going to use Choc switches with a conductive case (like aluminium or FR4 plates), you'll also want to get a set of SMD diodes. You won't be able to clip the legs of axial diodes short enough to avoid accidental shorts.

What's optional?

And lastly, you can get these options to add some bling to your keyboard:

What is the Aurora Series?

The Aurora series were designed as a homage to open source keyboard kits that have carved their space into the community. Kits that provided something new and unique, kits that resonated with the community and that have both received and have given a lot of love in return.

With the Aurora series, we aim to make these kits available to the community in a way that both honors the original, while also offering the best possible feature set and a consistent, well-documented build experience.

For each kit sold, we give back to the community by donating €1 across the firmware projects we support. This way we support open source projects and benefit everyone using keyboards, whether they use our kits or their own.

Build Guide

Check out the Aurora Build Guide on our documentation site.


The LEDs on all Aurora kits are north-facing. This means they'll light up any legends that may be on your keycaps nicely, provided they're translucent. The caveat of this, is that Cherry-profile keycaps (such as by those by GMK) may interfere with the switch housing. Other keycap profiles together with MX-style switches, along with Kailh low profile choc switches, are all not affected.

Kailh Choc low profile switches and encoders aren't compatible due to current plate options. You can still use them, but you'll want to modify the plate files and cut your own, or modify a store-bought plate with a tool like a file or Dremel.
