From the project

An Open Source CircuitPython-compatible PCB badge that can (maybe) tell the future!

Hardware, software, and other resouces for a fun little CircuitPython-compatible PCB badge!

Note: Lots of information and improvements to be added soon!

All of the hardware design files are included in the hardware/ directory. The board was designed with KiCad 7, using mostly components from JLCPCB's Assembly Parts Library.

The Magic 8-Badge was created to utilize Adafruit's CircuitPython 🐍, and will hopefully have a board definition available on the CircuitPython website soon. The v1 version of the Magic 8-Badge distrbuted at PhreakNIC 24 in Nov 2023 are runnings a slightly-modified…

Magic-8-badge: common questions

What microcontroller does the Magic-8-badge use?

The Magic-8-badge is built around the RP2040, from the RP2040/RP2350 family.

How big is the Magic-8-badge PCB?

The Magic-8-badge measures 84 × 84 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Magic-8-badge?

63 components, from 34 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 Magic-8-badge design files?

From the tylercrumpton/magic-8-badge 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 Magic-8-badge design in my own project?

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

Can I test firmware for the Magic-8-badge without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
