Introduction

The university of YRGO anually hosts an autonomous rc-car grand prix between the two first year electronic-engineering classes. The classes are split into three groups per class, where each group is tasked with the goal to design and construct a fully autonomous rc car to compete in the YRGO grand prix of that year. The car races three competing cars simoultaneously on the track where the car that finishes the most laps in 3 minutes is crowned the winner. The grand prix consists of a group stage, quarter finals, semi finals and the final.

Questions

How big is the DBT 4.0 PCB?

It measures 180 × 56 mm and has 2 copper layers, 1.6 mm thick.

What parts does the DBT 4.0 use?

16 parts, built around the VL53L1X. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the DBT 4.0 KiCad files?

From the MaxJ02/Death_By_Table repository on GitHub, at the commit this page was made from: the board is DBT_4.0/DBT_4.0.kicad_pcb and its schematic DBT_1/Death_by_table.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the DBT 4.0 design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
