Raspberry Pi/Electronics

Hello, I'm Arocchi.

With the advent of Raspberry Pi Pico W, the RP2040 (Raspberry Pi Pico) is now equipped with Wi-Fi. Pico compatible boards are available.

I just got this one and would like to introduce it to you.

I got it from Marutsu Online .

In this article, we will try it with Arduino (C/C++).





  • Raspberry Pi Pico compatible board
  • Built-in WiFi module WizFi360-PA
  • reset button
MCURP2040 dual-core ARM Cortex M0+ processor, up to 133 MHz operating frequency
flash memory2MB
GPIOs26 (pinout compatible with Raspberry Pi Pico)

About Wi-Fi module WizFi360-PA

It will be a so-called skill-compliant module.

RP2040 board summary article (reference site)





There is a reset button that the Raspberry Pi Pico didn't have


You can check the pin silk printing

USB mass storage mode

If you press the reset button while pressing the BOOT button, it will enter USB mass storage mode (RPI-RP2).

When in USB mass storage mode, you can install MicroPython or CircuitPython firmware from your PC.

Please refer to the following articles for how to install MicroPython and CircuitPython firmware.

You can use the firmware of Raspberry Pi Pico.


Arduino IDE settings

  • Add board to Arduino

Add Raspberry Pi Pico/RP2040 board ( earlephilhower version ) in advance.
See the article below for how to add.


  • Installing the Raspberry Pi Pico/RP2040 board

Install the Raspberry Pi Pico/RP2040 board by clicking Tools > Boards > Board Manager and entering 'rp2040' in the search box.

  • board selection

Select [Tool] > [Board] > [Raspberry Pi RP2040 Boards(Ver)] > [WIZnet WizFi360-EVB-Pico].

  • Serial port selection

Select the serial port to which WizFi360-EVB-Pico is connected from [Tools] > [Serial Port].

If you have an environment that cannot write from a serial port, such as a Chromebook, you can write sketches manually.


Install WizFi360 library


The library for WizFi360-EVB-Pico is below (GitHub).


Download the ZIP file from Code > Download ZIP .


Arduino IDE

Sketch > Include Library > Install .ZIP Library…


Select the downloaded ZIP file to install.

Sample program (Arduino sketch)

Sketch example

Arduino IDE File > Example Sketch > Try some WizFi360 sketches.

Connect WPA

Open the example sketch ConnectWPA .

Replace the following (Wi-Fi information) with the Wi-Fi information of the connection destination and write the sketch.

/* Wi-Fi info */
char ssid[] = "wiznet";       // your network SSID (name)
char pass[] = "0123456789";   // your network password

You can check the information of the connected Wi-Fi from the serial monitor.

Web Server AP

Sketch example Open WebServerAP and write a sketch.

WizFi360-EVB-Pico is WebServer, so try to connect.

  • Connection example with a smartphone (iPhone)

Tap wiznet from Wi-Fi.

Enter "0123456789" for the password and tap "Connect".

If you open the wiznet information (tap the i mark), you can see that the IP address (router) is "".

When you access from your browser , the following is displayed.
