# 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](https://github.com/red-scorp/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.
Preview:
You can view the [Schematics in PDF format](doc/RP2350-Eins.pdf) for detailed information.
STEP 3D file is available [with pins](doc/RP2350-Eins.step).
Features:
- Arduino UNO compatible pinout
- Partially compatible with Arduino Nano RP2350 Connect pinout
- Dual-core Cortex-M0+ Raspberry Pi RP2350
- 21 GPIO pins, including 4 analog inputs
- USB Type-C connector
- JTAG and DBG debugging connectors
- LDO-based 5V and 3.3V power supply with a maximum 12V input
- Supports both SOIC and WSON 16MB flash packages
- Includes power, user and RGB LEDs
CAM files, as well as the BOM and CPL files for JLCPCB, are available.
