The premium PCB comes with an ENIG layer to improve both durability and ease of soldering while adding a bit of aesthetic appeal. For your convenience, it comes pre-programmed with the below layout and LED lighting setup, though the board supports TMK-keyboard firmware that allows you to fully customize every aspect of the firmware. All base components such as the diodes and micro-controller have been pre-soldered, so all you have to do is solder your choice of LEDs and switches. Supporting various layouts, the anodized aluminum plate is available in a variety of colors, adding another layer of customization to your board. The cutouts allow for switch top removal, which makes any future mods, like swapping out springs or stems, a breeze.
