- **WIZnet W5500-EVB-Pico2** x 1 ([docs](https://wiznet.io/products/powered-by-raspberry-pi/w5500-evb-pico2))
- **WIZnet W5100S-EVB-Pico2** x 1 ([docs](https://wiznet.io/products/powered-by-raspberry-pi/w5100s-evb-pico2))
- Software: **MicroPython** ([docs](http://micropython.org/))

## Article

Currently, the officially supported WIZnet development boards for MicroPython are **W5500-EVB-Pico** and **W5100S-EVB-Pico**.

![](https://maker.wiznet.io/upload/ckeditor5/15724686%5F1740759926%2Epng)

- However, to enhance usability, I have submitted a pull request(PR) requesting official support for the **W55RP20-EVB-Pico**. The newly submitted PR supports **Pico SDK 2.1.0**, so if you found the existing repository's code inconvenient, please refer to the code in this [PR](https://github.com/micropython/micropython/pull/16476).

> [**https://github.com/micropython/micropython/pull/16476**](https://github.com/micropython/micropython/pull/16476)

[This link contains MicroPython examples](https://github.com/WIZnet-ioNIC/WIZnet-ioNIC-micropython-examples.git) for the W55RP20-EVB-Pico.

Build the PR firmware and test it!

Since this PR is still in progress, please use it for reference only. Additionally, I have uploaded the PR's code to [the existing repository](https://github.com/WIZnet-ioNIC/WIZnet-ioNIC-micropython/tree/master) and am in the process of adding more examples.

- Here is a PR for the **EVB Pico2 series**. **(W5500-EVB-Pico2, W5100S-EVB-Pico2)**

Please refer to the link below for more details!

> [**https://github.com/micropython/micropython/pull/16280**](https://github.com/micropython/micropython/pull/16280)

For building the MicroPython code, please refer to the article below.

Although this post is about an ongoing PR, I hope it will be helpful to many MicroPython users.

Thank you!
