## Components

- **WIZnet W5500** x 1 ([docs](https://docs.wiznet.io/Product/Chip/Ethernet/W5500))

WIZnet parts: W5500 ([Datasheet](https://docs.wiznet.io/Product/Chip/Ethernet/W5500/datasheet?utm_source=maker&utm_medium=project&utm_campaign=w5500), [product hub](https://maker.wiznet.io/products/w5500/))

## Article

**INTRODUCTION**

The W5500EVB uses the STM32F103RCT6 mainstream MCU. The W5500 interacts with the MCU through a standard four-wire high-speed SPI interface. The W5500's outstanding hardware TCP/IP stack core not only provides eight independent communications, but also is fast, secure, and stable, and is widely used in the industrial field.

**FEATURES**

Evaluation board based on 32-bit ARM Cortex-M3 W5500 chip Hardware pin compatible with Arduino Uno Rev.3 Support 1 button switch (SW), 1 RGB LED Supported 1 Ethernet port connector / USB-micro Type B connector Supported ISP and SWD interfaces Provide a variety of reference code - loopback, DHCP, DNS.

**TECHNICAL DETAILS**

- MCU: STM32F103RCT6 Cortex-M3

- Ethernet: W5500 (WIZnet hardwired TCP/IP)

- Power: 5V DC power supply

- Extended I/O: 51 GPIOs (including analog peripherals using 12-bit ADCs)

- RJ-45: Single channel 10/100 Base-TX RJ-45 (57-00013QL11-1 / UDE)

- USB: USB Micro-B type (onboard USB to UART IC, USB BUS power / CP2104) - for debugging

- Onboard user interface: 1 x RGB LED
