The **01Studio W5500 Ethernet Module** is an SPI-based wired network module built around the WIZnet W5500 Ethernet controller. It enables developers to add Ethernet capability to a variety of MicroPython development boards and MCU platforms with minimal hardware integration.

This integrated design allows developers to implement Ethernet connectivity without requiring any additional external circuitry.

## About 01Studio

**01Studio** is a hardware manufacturer focused on Python and MicroPython-based embedded development.
Their product lineup includes:

- MicroPython development boards (STM32, RP2040, ESP32 based)

- IoT communication modules

- Sensor, camera, and display modules

- Educational kits and supporting materials

Each product is accompanied by documentation, example code, and hardware resources on the official website.

## Compatibility with MicroPython Development Boards

In addition to 01Studio’s MicroPython boards, this module can be considered in relation to WIZnet’s official Ethernet modules such as **WIZ550io**, **W5500-io**, and **W5500-EVB**.
While those official modules are designed primarily for general-purpose embedded development and reference designs, the 01Studio W5500 Ethernet Module focuses specifically on **MicroPython accessibility and ease of integration**.

Key differences include:

- **Target Audience**:
  WIZnet official modules are aimed at hardware developers building custom systems, whereas the 01Studio module targets MicroPython learners and rapid prototyping.

- **Integration Style**:
  Official modules provide standardized pinouts and robust reference hardware, while the 01Studio module aligns its pin layout directly with 01Studio MicroPython boards for plug-and-play development.

- **Software Environment**:
  WIZnet modules include low-level C drivers and reference examples, whereas 01Studio complements its hardware with MicroPython-friendly libraries and documentation.

Because of these differences, the 01Studio W5500 Ethernet Module is not a replacement for official WIZnet hardware, but rather a **MicroPython-oriented variant** built to simplify Ethernet development within the 01Studio ecosystem.

## Typical Use Cases

The 01Studio W5500 Ethernet Module can be applied in:

- Ethernet-based IoT device development

- Network programming education and training

- Simple MicroPython-based web servers

- TCP/UDP-based sensor data transmission

- Environments that require stable wired Ethernet instead of Wi-Fi
