What microcontroller does the Inercia floppy badge use?

The Inercia floppy badge is built around the RP2040, from the RP2040/RP2350 family.

How big is the Inercia floppy badge PCB?

The Inercia floppy badge measures 90 × 97 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Inercia floppy badge?

76 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 Inercia floppy badge design files?

From the afonsus1997/Inercia-floppy-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 Inercia floppy badge design in my own project?

The repository has no license, so all rights stay with afonsus1997. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Inercia floppy 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.
