Hardware Configuration

  • RJ-45 with Transformer : Ethernet Port
  • W5500 : a hardwired TCP/IP Ethernet Controller
  • RESET : Reset Ethernet shield and Arduino when pressed
  • SD-Slot : support Micro SD card in FAT16 or FAT32 ; (Please Read the Caution)
  • I2C : I2C interface
  • UART : UART interface

Pins usage on Arduino & ARM mbed

W5500 Ethernet shield is User Selectable GPIO

  • The user is able to use different Modules by changing Chip Select
  • Stackable : Possible to stack different modules

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.
