The Vortex Core is an amazing little keyboard with an aluminum body, good keycaps and a slim design. Unfortunately though, it needs one thing to be a perfect 40% board, which is programmability.

The Atom47 is a drop-in replacement PCB for the Vortex Core to be able to change the function of every key using QMK, which allows you to have a virtually unlimited amount of layers and keys. Suit your Vortex Core to your needs, so to say.


  • QMK Firmware
  • 6 Underglow RGB leds
  • In-switch leds
  • Through-hole micro usb connector (less likely to break off!)
  • South facing leds for the QMX/Zealencio users
  • Multiple layouts
  • Easily reachable reset button under the spacebar

How to use

Every Atom47 comes pre-flashed with the default layout as found in the QMK repo. To enter programming/flashing mode, press Pn and then the right Ctrl key or use the reset key marked on the keycaps. To exit programming mode, press Esc or unplug the USB cable. Most QMK users should already have a build environment set up, but new users should definitely follow the documentation.

How to install

The installation of the Atom47 requires you to desolder every switch of your Vortex Core and solder the new PCB in. It’s that easy. Here’s a build log from someone who got a rev2 prototype, which can help you during the installation.


You can get a PCB from me, see the shop page for more info.

Rev1 / Rev2
[table id=2 /]


Rev1 failed, as it didn’t have the proper USB pins and didn’t have a hole for the plate standoff. Only one has been made.

Rev2 was a huge improvement as the USB port actually worked, and this also was a more rigid port. Only 10 have been made and about 8 of them have been sent to other people. It also featured a WS2812B LED under the spacebar for layer indication.

Rev3 (Round 1)
Rev3 is the first ‘final’ revision, as this is the one made in the first round of the group buy on Reddit and Geekhack. It doesn’t feature a single WS2812B LED on the front, but 6 on the back for future use/custom cases. It also has a standard ISP header and proper decoupling capacitor placement along with support for a few different layouts. Another addition is the single caps lock LED on the front.
