# Robotics

The Robotics module's schematic and board, KDROB001 revision 1.0, viewable here and downloadable as KiCad sources.

## What it is

The Robotics module carries an AT8833CQ dual H-bridge on the 5 V rail, two screw terminals for the motors, a servo header, an I2C port with its pull-ups, a sensor header, and the current-sense and fault network around the driver. Two copper layers. The module's page, `modules/robotics`, says what it does and which GPIO is which; this page is the schematic.

Revision 1.0, released 2026-09-14, drawn in KiCad 10. Symbols, footprints and 3D models come from Kode's shared hardware library.

## Schematic

Zoom with the wheel, drag to pan, and switch sheets from the toolbar.

## Files

The schematic sources, as published here. Open the `.kicad_pro` in KiCad 10 with the sheets beside it. The cover sheet's embedded fonts were removed from these copies and the project's text variables written in; the design is unchanged. The board layout is not published.
