Rp2350-gpio card: common questions

What microcontroller does the Rp2350-gpio card use?

The Rp2350-gpio card is built around the RP2350_60QFN, from the RP2040/RP2350 family.

How big is the Rp2350-gpio card PCB?

The Rp2350-gpio card measures 26 × 30 mm, has 2 copper layers and is 1.659981 mm thick.

How many components are on the Rp2350-gpio card?

36 components, from 18 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 Rp2350-gpio card design files?

From the semitov/rp2350-gpio-card 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 Rp2350-gpio card design in my own project?

Yes, under the terms of its CC-BY-4.0 license, which semitov chose for the repository.

Can I test firmware for the Rp2350-gpio card 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.
