About the Maglev driver PCB

Maglev driver is an open source STM32 PCB design by Janky-Jingle-Crew, published on GitHub. It is a 4-layer board measuring 85 × 85 mm, with 53 components from 25 distinct parts.

Its main chip is the C529331, from the STM32 family. Other key parts include the C5446, C181752, C39159 and C3716049. By type, the board carries 22 capacitors, 8 ICs, 7 resistors, 3 diodes and 1 connector.

2025 Christmas card "South Pole Levitator"

Janky Jingle Crew is back this Christmas as well! We are continuing with the theme of magnetic propulsion from last year, but this time for levitation!

We were aiming to build a batch of around 50 units, so coil winding quickly became a bottleneck. That led us to PCB coils as a more scalable solution. Mounting the coils was another pain point, gluing them down and then soldering wires (like many existing kits do) felt messy. Instead, we combined the mounting and electrical connection using solderable standoffs.

Maglev driver: common questions

What microcontroller does the Maglev driver use?

The Maglev driver is built around the C529331, from the STM32 family.

How big is the Maglev driver PCB?

The Maglev driver measures 85 × 85 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Maglev driver?

53 components, from 25 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 Maglev driver design files?

From the Janky-Jingle-Crew/SouthPoleLevitator 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 Maglev driver design in my own project?

The repository has no license, so all rights stay with Janky-Jingle-Crew. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Maglev driver without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
