Main Board 2023: common questions
What microcontroller does the Main Board 2023 use?
The Main Board 2023 is built around the Teensy3.5_All_Pins, from the NXP family.
How big is the Main Board 2023?
The Main Board 2023 measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Main Board 2023?
61 components, from 22 distinct parts. The full bill of materials is listed on this page.
Where can I download the Main Board 2023 design files?
From the LesKaribous/Karibous-2024-Hardware 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 2023 design in my own project?
The repository has no license, so all rights stay with LesKaribous. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Main Board 2023 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.
