Rp2350b minimal board design files

The KiCad project lives in the Adidez/rp2350b-minimal-board repository on GitHub; these links point at the commit this page was built from.

Rp2350b minimal board: common questions

What microcontroller does the Rp2350b minimal board use?

The Rp2350b minimal board is built around the RP2350B A4, from the RP2040/RP2350 family.

How big is the Rp2350b minimal board?

The Rp2350b minimal board measures 52 × 71.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rp2350b minimal board?

45 components, from 21 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 Rp2350b minimal board design files?

From the Adidez/rp2350b-minimal-board 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 Rp2350b minimal board design in my own project?

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

Can I test firmware for the Rp2350b minimal board 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.
