W5500 Ethernet Shield

Overview

ARM mbed compatible operation
Arduino Pin-compatible
Ethernet (W5500 Hardwired TCP/IP chip)

W5500 Ethernet shield is designed using the WIZnet W5500 chip. Please click the link for the further information about W5500. It supports both 3.3V & 5V. This Ethernet Shield is compatible with Arduino and ARM mbed Platform.

Available Board List

ARM mbed Board
- ARM mbed Platform : ARM mbed platform Site
- FRDM-KL25Z : Freescale
- NXP LPC800-MAX : NXP
Arduino Board
- Arduino board (e.g. the Uno, Mega, Due)
- Arduino Leonardo
Arduino-compatible Board

I2C : I2C interface
UART : UART interface

Pins usage on Arduino & ARM mbed

W5500 Ethernet shield has several configurable GPIOs

When you operate it with other modules, you may need to change 'Chip Select' pin to a different one.
W5500 INTn pin is linked to D2 (2,3 Short). So, if you need INTn pin. You soldering to 0R Resistor to Dx pin

Caution) When the user uses 5V Platform, we cannot confirm a stable operation of SD-CARD. Therefore, though 5V Platform is safe to use after going through enough tests, it is highly recommended to mount buffer & 100nF Capacitor for a secure operation.

SPI Operation & Timing Diagram

SPI Operation

There is a W5500 inside W5500 Ethernet shield. Therefore SPI operation & Timing Diagram of Ethernet shield follows one of W5500. For more information about W5500 chip please also refer to the chip's datasheet:

Do you want to develop new this product? Please look at the Rev 1.01_Customize circuit
Rev 1.01 removed the buffer ICs from Rev 1.0 circuit
Because, Buffer IC was limited delay speed.
Arduino compatible INT(R25) remove
