RP2350-Eins Project

The RP2350-Eins project aims to create a replacement for the Arduino UNO R3 or Arduino M0 using the RP2350 MCU. This project was born as a continuation my previous project, RP2040-Eins, which was based on the Raspberry Pi RP2040 MCU.

RP2350-Eins Board

The RP2350-Eins board is a 4-layer design intended to accommodate the popular Raspberry Pi RP2350 MCU within the standard Arduino UNO R3 footprint.

This board is crafted in Germany, and its name, "RP2350-Eins", incorporates the German word "Eins" (pronounced as "eye-ns"), which translates to "one". This name choice reflects the use of the same form-factor as the Arduino "Uno", which means "one" in Italian.
