From the project
Hardware project of MOD Duo X
This repository contains the schematics and PCB design files for the MOD Duo X.
The MOD DuoX bottom-board is done in Kicad 5. The other board (controller board) is done in Altium.
Please, use KiCAD 5 to edit the project.
The master branch has the most recent version of the bottom-board project, made for the Duo X.
The rev20161129-updated` branch has the legacy production version of the MOD Duo boards.
