Les Karibous est une équipe française de robotique fondée en 2011. L’objectif de l’équipe est de montrer que la robotique peut être simple et fun à réaliser.

Depuis sa création, Les Karibous participent chaque année à la Coupe de France de Robotique (organisée par l’association Planète Sciences), ainsi qu’à la compétition MakerFight. Cette approche axée sur le plaisir et la simplicité se reflète dans leurs projets et leurs résultats en compétitions.

Main Board 2025: common questions

What microcontroller does the Main Board 2025 use?

The Main Board 2025 is built around the Teensy4.1, from the NXP family.

How big is the Main Board 2025?

The Main Board 2025 measures 56 × 151 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Main Board 2025?

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

Where can I download the Main Board 2025 design files?

From the LesKaribous/leskaribous.github.io repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Main Board 2025 design in my own project?

Yes, under the terms of its MIT license, which LesKaribous chose for the repository.

Can I test firmware for the Main Board 2025 without the hardware?

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