Defcon32-Badge: common questions

What microcontroller does the Defcon32-Badge use?

The Defcon32-Badge is built around the SC0918, from the RP2040/RP2350 family.

How big is the Defcon32-Badge PCB?

The Defcon32-Badge has 2 copper layers and is 1.6 mm thick.

How many components are on the Defcon32-Badge?

46 components, from 27 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 Defcon32-Badge design files?

From the hamster/Defcon32-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 Defcon32-Badge design in my own project?

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

Can I test firmware for the Defcon32-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.
