Quad coils
About the Quad coils PCB
Quad coils is an open source PCB design by Janky-Jingle-Crew, published on GitHub. It is a 4-layer board measuring 70.4 × 70.4 mm, with 8 components from 3 distinct parts.
By type, the board carries 4 connectors and 4 inductors.
From the project
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.

Quad coils: common questions
How big is the Quad coils PCB?
The Quad coils measures 70.4 × 70.4 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Quad coils?
8 components, from 3 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 Quad coils 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 Quad coils 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.
