# Running W55RP20 on 200 MHz using Micropyton

## Question

Asked by jewest on 2025-08-07 in MCU & Boards.

Hello,

I am using the official repro from wiznet and I have the W55RP20 running on 125 MHz.

The application works but I need some processing power to make the user experience a bit better. set the CPU to 133 with the frequency command.

During my search I found that the chip now is officially supported with 200MHz option.

But the repro of wiznet is not up to date with the main trunk.

and the W55RP20_EVB_PICO is not added to the main trunk.

So how do I get the latest code for the W55RP20_EVB_PICO?

This is not a genuine reply — it's clearly an AI or auto-generated response. It doesn't address the issue and even points back to the same form for a solution. Completely unhelpful.

Hello,
The W55RP20 is not yet officially supported in MicroPython.
Currently, an official Pull Request for support is in progress.
