# W55RP20-EVB-PICO　面白いよ！

> Beginner-friendly Arduino guide for W55RP20-EVB-PICO: step-by-step setup, BOOT+RUN flow, and first Blink upload—curated from a Japanese tutorial.

Original author: kitagami (source: https://zenn.dev/nonnoise/articles/d871f6136f5b9e)

## Article

## Overview

This tutorial introduces how to get started with the **W55RP20-EVB-Pico**, a development board built on **W55RP20**, which integrates Raspberry Pi RP2040 and WIZnet W5500 into a single SiP.
It walks through adding the Boards Manager URL, selecting the correct board and port, entering **BOOT+RUN manual bootloader mode**, and uploading the Blink sketch—covering exactly the points where beginners often struggle.

---

## Original Language & Author

The original article was published in **Japanese** on **Zenn** (Nov 16, 2024).
The author, **Yuta Kitagami (@nonNoise)**, is the co-founder of **ArtifactNoise, LLC** and an inventor who frequently writes about embedded systems and IoT. By providing the tutorial in Japanese, he ensures accessibility for Japanese makers—using local UI terms and linking to domestic distributors such as Switch Science.
This curation presents the same reproducible steps in **English**, making the content useful for a global audience.

---

## Key Highlights

**Boards Manager URL**
Add the following JSON URL in Arduino IDE > Preferences > **Additional Boards Manager URLs**:

`https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json`

**Core Selection**
The Mbed-based RP2040 core is deprecated; install the **User (Philhower)** version instead.

**Manual BOOT Mode**
Press and hold **BOOT**, then press and release **RUN** to mount the board as a USB mass storage device.
If skipped, the log may show **“No drive to deploy.”**

**Board & Port Selection**
Choose **“WIZnet W55RP20-EVB-PICO”** in Tools > Board, select the correct USB port, then upload the Blink example.

**Next Steps**
With RP2040 and W5500 integrated, the board supports networking demos (HTTP server, SNTP clock, MQTT) and is **AWS IoT Core Qualified**.

---

## Why It Matters

**For Japanese users**: The original language and domestic links make the tutorial especially easy to follow and replicate in Japan.

**For global makers**: This English curation preserves all critical strings (URLs, board names, error messages), ensuring reproducibility across languages.

**For beginners**: It prevents common pitfalls—like upload failures due to missing BOOT mode—saving time and frustration.

---

## Quick Reproduce (Checklist)

Install Arduino IDE → Add RP2040 Boards Manager URL.

Install **Earle Philhower RP2040 (User)** core.

Connect board → Enter BOOT mode (BOOT + RUN).

Select **W55RP20-EVB-PICO** board and port → Upload Blink.

If **“No drive to deploy.”** appears, repeat BOOT procedure.
