RP2040 Minimal Design Example: common questions

What microcontroller does the RP2040 Minimal Design Example use?

The RP2040 Minimal Design Example is built around the C97521, from the RP2040/RP2350 family.

How big is the RP2040 Minimal Design Example PCB?

The RP2040 Minimal Design Example measures 52 × 51 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RP2040 Minimal Design Example?

30 components, from 14 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 RP2040 Minimal Design Example design files?

From the rompasaurus/dilder 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 RP2040 Minimal Design Example design in my own project?
