REDOX PCB Set – Reversible (Left + Right)

REDOX PCB Set – Reversible (Left + Right)

This PCB set contains two reversible printed circuit boards (for the left and right side) that form the base of the Redox split keyboard.

The boards are made from 1.55 mm thick black laminated PCB, similar to the classic Cherry® G80 keyboards. The copper layer is 70 μm thick, ensuring very good electrical conductivity and durability.

The REDOX PCB is designed primarily for DIY keyboard builds. FalbaTech cannot be held responsible for damage caused by incorrect assembly, soldering, or installation. You build and use it at your own risk.

Original REDOX PCB design by Mattia Dal Ben (aka u/TiaMaT102)

Current version: Revision 06.12.2025 by FalbaTech

FalbaTech modifications

This version includes several practical improvements compared to the original design:

HotSwap support

The PCB is fully compatible with Kailh HotSwap sockets, allowing switches to be installed and replaced without soldering.

Integrated RGB lighting

An RGB strip has been integrated directly into the PCB.

There are 7 LEDs per half that can be soldered to the board. The LEDs face upward toward the switches.

If you use switches with RGB windows, the light will pass through and be visible from the top.

This is not per-key RGB backlighting, but it still creates a pleasant and subtle lighting effect.

Controller relocation

The controller has been moved from the center of the PCB to the side, exactly where the battery was located in the wireless version.

Thanks to this change the PCB is fully compatible with Redox wireless cases (the version with the receiver).

Switch compatibility

This PCB is designed for standard mechanical switches (Cherry MX compatible) and does not support low-profile switches.
