RP2350: common questions

What microcontroller does the RP2350 use?

The RP2350 is built around the RP2350A-QFN60, from the RP2040/RP2350 family.

How big is the RP2350 PCB?

The RP2350 measures 59 × 25.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the RP2350?

59 components, from 28 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 design files?

From the sai-ydev/air_quality_wearable 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 design in my own project?

Yes, under the terms of its MIT license, which sai-ydev chose for the repository.

Can I test firmware for the RP2350 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.
