This repository hosts the LaTeX sources for the official documentation shipped with every Digifiz Replica dashboard. The manuals cover both hardware generations—the classic Arduino Mega (ATmega2560) cluster and the Digifiz Next ESP32-based units—and are kept in sync with the production firmware and wiring harnesses.
- Full installation and configuration guide explaining wiring, calibration, firmware flashing, and safety notes for each hardware revision.
- Feature reference detailing onboard diagnostics, display modes, warning logic, and localization options available in the latest firmware.
- Appendices for technicians with connector pinouts, signal tables, sensor compatibility, and troubleshooting flows collected from the community.
The compiled PDF (DR_DRNext_User_Manual_mk1_mk2.pdf) is the master document used for customer deliveries. Each section of the manual lives in the chapters/ directory, supporting data and macros reside in preamble/, while ancillary assets (figures, tables, and scripts) are stored under figures/ and anc/.
Digifiz Replica is a modern replacement for factory VDO clusters in second-generation Volkswagen Group vehicles and now also in classic Audi platforms. Hundreds of units are already in the field, with active deployments in the USA, Germany, the UK, Italy, Russia, and across the EU.
