B-Sides 2024: common questions

What microcontroller does the B-Sides 2024 use?

The B-Sides 2024 is built around the RP2040, from the RP2040/RP2350 family.

How big is the B-Sides 2024 PCB?

The B-Sides 2024 measures 99.5 × 124.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the B-Sides 2024?

147 components, from 46 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 B-Sides 2024 design files?

From the OklahomaOpenSourceHardware/OKC-OSH-2024-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 B-Sides 2024 design in my own project?

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

Can I test firmware for the B-Sides 2024 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.
