Rp2350b launchpad: common questions

What microcontroller does the Rp2350b launchpad use?

The Rp2350b launchpad is built around the C424093, from the RP2040/RP2350 family.

How big is the Rp2350b launchpad PCB?

The Rp2350b launchpad measures 58.4 × 83.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rp2350b launchpad?

122 components, from 54 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 launchpad design files?

From the Terstegge/rp2350b-launchpad-PCB 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 launchpad design in my own project?

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

Can I test firmware for the Rp2350b launchpad 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.
