Repulsive Maglev: common questions
What microcontroller does the Repulsive Maglev use?
The Repulsive Maglev is built around the ESP32S3WM1UN16R8, from the ESP32 family.
How big is the Repulsive Maglev PCB?
The Repulsive Maglev measures 280 × 145 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Repulsive Maglev?
103 components, from 36 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 Repulsive Maglev design files?
From the fe871bae/Repulsive_Maglev 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 Repulsive Maglev design in my own project?
The repository has no license, so all rights stay with fe871bae. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Repulsive Maglev 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.
