About the Mario Kart PCB

Mario Kart is an open source ESP32 PCB design by Wyphorn, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 56 × 50 mm, with 42 components from 28 distinct parts.

Its main chip is the ESP32-C6-SUPERMINI, from the ESP32 family. Other key parts include the DFPlayer Mini, LSM6DS3 and AP63205WU. By type, the board carries 17 resistors, 9 capacitors, 7 connectors, 4 ICs, 3 transistors and 1 switch.

From the project

Mario-Kart-inspiriertes RC-Rennsystem: umgebaute Carrera-Autos, ESP32-C6, ESP-NOW, eigene Fernbedienung – Fan-Projekt, entstanden mit KI (Claude)

Mario-Kart-inspiriertes RC-Rennsystem für 8 Fahrzeuge im Außeneinsatz. Die Autos fahren mit ~30 km/h; Items, Kollisionen und Rundenzählung werden automatisch erkannt.

Das Projekt ist auf Nachbau ausgelegt: Alle Bauteile haben eine feste Bestellnummer eines echten Herstellers mit öffentlichem Datenblatt und sind handlötbar (SOT-23, SOT-223, SMA, THT – kein QFN).

Mario Kart: common questions

What microcontroller does the Mario Kart use?

The Mario Kart is built around the ESP32-C6-SUPERMINI, from the ESP32 family.

How big is the Mario Kart PCB?

The Mario Kart measures 56 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mario Kart?

42 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mario Kart design files?

From the Wyphorn/MarioKartRC repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Mario Kart design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Mario Kart without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
