Hardware Specification

Schematic & Parts List & Gerber Files

Dimensions V1.0 (unit: mm)

       The W5100S-EVB-Pico pin output is directly connected to the GPIO of the RP 2040, as shown in the figure above. It is the same as Raspberry Pi Pico board, but GPIO 16, GPIO 17, GPIO 18, GPIO 19, GPIO 20, GPIO 21 are connected to W5100S inside the board, these pins support SPI. Communication with W5100S uses Ethernet function. If you are using the Ethernet functionality, these pins cannot be used for any other purpose. The RP 2040 GPIO used inside W5100S-EVB-Pico is shown below.

• Besides the GPIO and ground pins, there are 7 other pins on the main 40-pin header:

Working Environment

The recommended maximum ambient temperature is 70°C.

Development Environment Configuration

Development Environment: Windows10/11，Visual Studio Code

Hardware Preparation：W5100S-EVB-Pico board，Ethernet Cable，Micro USB

Step 1: Download Compilation Tools
First download the official compilation tool of Raspberry Pi: GitHub - raspberrypi/pico-setup-windows

The tool integration includes the following software:

• Arm GNU Toolchain
• CMake
• Ninja
• Python3.9
• Git for Windows
• Visual Studio Code
• OpenOCD

Step 2: Install the program
Install after the download is complete

Choose the installation path

Click Finish

​ ​

First Program

USB virtual serial port printing example

      Find Visual Studio Code in the start menu. After opening, it will automatically load the sample program we just downloaded. Open the hello_usb.c file under the usb folder under the hello_world folder. The function of this example is to automatically print "Hello, world" through the USB port."

Click the tool icon at the bottom and select Pico ARM GCC as our compilation chain

Select the CMake tool on the left, click the download button behind the hello_usb file to generate the execution file

After opening the file, press and hold the BOOT button on the Raspberry Pi, then drag the .uf2 file to the RP1-RP2 virtual U disk to complete the program burning.
