===Backlit version===
Work has been going to make an official backlit version of the ErgoDOX.

The backlit PCB uses a single "high power" SMD mounted RGB LED on each half connected to high efficiency LED drivers controlled by PWM and [[I²C]] bus. On top of the LED there is a light pipe which directs the light into .75mm fiber optic strands, these are then individually routed on the back of the PCB to each switch where they are fixed using the standard LED hole in the PCB/Switch. This gives the ability for the back-light on each half to be dynamically set to any RGB value.

The development is hosted on [https://github.com/jalli/ErgoDox GitHub]. The new back-light enabled PCB fixes the outermost key columns bug and is fully backwards compatible, it will function as the original when the back-light components are absent.

The following table lists the additional components required for the back light:

|LPF-R011362S 90° Light tube, square end.

Total additional cost is expected to be between 15-20 dollars for both halves depending on volume. Existing cases can be modified for the backlit PCB by removing material to make room for the light tube.
