An Ethernet Expansion Module Designed for MicroPython Development Boards

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
