RP2350-based board with footprint of Arduino ProMini

The RP2350-ProMini project aims to create a replacement for the Arduino Pro Mini using the RP2350 MCU.

The RP2350-ProMini board is a 4-layer board designed to accommodate the popular Raspberry Pi RP2350 MCU in the commonly used, but obsolete, Arduino Pro Mini footprint.

This project is a shoot-off from my earlier RP2040-ProMini project, which was designed to accommodate the Raspberry Pi RP2040 MCU in the same footprint.

RP2350-ProMini: common questions

What microcontroller does the RP2350-ProMini use?

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

How big is the RP2350-ProMini PCB?

The RP2350-ProMini measures 17.8 × 41.9 mm, has 4 copper layers and is 1.61 mm thick.

How many components are on the RP2350-ProMini?

46 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-ProMini design files?

From the red-scorp/RP2350-ProMini 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-ProMini design in my own project?

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

Can I test firmware for the RP2350-ProMini 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.
