Overview

AURA (Autonomous Universal Robotics Architecture) is a modular set of PCBs designed for robotics applications. This repository includes schematics, layouts, and KiCad project files to facilitate prototyping and production.

The software framework to run on this hardware can be seen in another repository here.
