## Description

The WIZnet W5100S-EVB-Pico2 combines the powerful Raspberry Pi RP2350 microcontroller with hardwired TCP/IP networking capabilities, creating an ideal platform for Internet of Things (IoT) development and networked automation projects. This versatile board enhances the popular Raspberry Pi Pico form factor by integrating robust Ethernet connectivity through the W5100S controller, while maintaining compatibility with existing Pico hardware and software ecosystems.

## Key Features

- Dual-core ARM Cortex-M33 processor running at up to 150MHz
- 520kB multi-bank SRAM and 16Mbit integrated Flash memory
- Hardwired TCP/IP controller supporting multiple internet protocols
- 4 independent hardware SOCKET connections
- 10/100 Mbps Ethernet with auto-negotiation
- USB-C connectivity for power and programming
- Enhanced security features including TrustZone and secure boot capabilities
- 48 programmable GPIO pins (with specific pins reserved for Ethernet functionality)

## How to Use

Setting up the W5100S-EVB-Pico2 is straightforward:

1. Connect the board via USB-C for power and programming
2. Install the necessary development environment (MicroPython, C/C++, or Arduino IDE)
3. Connect an Ethernet cable to the onboard RJ45 port
4. Upload your code using the drag-and-drop programming interface

Note that GPIO pins 16-21 are reserved for Ethernet communication:

| GPIO Pin | Function |
|---|---|
| GPIO16 | MISO |
| GPIO17 | CSn |
| GPIO18 | SCLK |
| GPIO19 | MOSI |
| GPIO20 | RSTn |
| GPIO21 | INTn |

## What's in the Box

- 1x WIZnet W5100S-EVB-Pico2 board

## Compatibility

The W5100S-EVB-Pico2 maintains pin compatibility with the [Raspberry Pi Pico 2](https://core-electronics.com.au/raspberry-pi-pico-2.html), making it suitable for existing Pico projects that require network connectivity. For projects requiring wireless capabilities instead of Ethernet, consider the [WIZnet WizFi360-EVB-Pico](https://core-electronics.com.au/wiznet-wizfi360-evb-pico-compatible.html).
