From the project

RP2350A Minimal Board KICad with USBC LCSC/JLCPCB parts

The primary goal of this project is to have a reference design for RP2350A, that uses USBC and has the LCSC/JLCPCB parts defined.

A secondary goal is to make the design physically small as possiable with one side SMD assembly.

RP2350A Minimal USBC: common questions

What microcontroller does the RP2350A Minimal USBC use?

The RP2350A Minimal USBC is built around the RP2350_60QFN, from the RP2040/RP2350 family.

How big is the RP2350A Minimal USBC PCB?

The RP2350A Minimal USBC measures 52 × 51 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RP2350A Minimal USBC?

39 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the RP2350A Minimal USBC design files?

From the funvill/RP2350A_Minimal_USBC repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the RP2350A Minimal USBC design in my own project?

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

Can I test firmware for the RP2350A Minimal USBC 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.
