Skateboard: common questions
What microcontroller does the Skateboard use?
The Skateboard is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the Skateboard PCB?
The Skateboard has 2 copper layers and is 1.6 mm thick.
How many components are on the Skateboard?
326 components, from 152 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Skateboard design files?
From the 86kkd/millionBoard repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Skateboard design in my own project?
The repository has no license, so all rights stay with 86kkd. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Skateboard 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.
