This Ethernet Shield is powered by a PIC32MX controller with an IP101GR PHY chip. This Ethernet Shield is NOT compatible with the Arduino Ethernet Library for Wiznet chips. See User Manual, examples and design files on Github. While the hardware design is public, the firmware on the PIC32MX controller is not. The PIC32MX on this board cannot run user firmware.

Features:

• 80MHz PIC32MX664F064H with unique MAC address
• extra 8 + 15 I/O pins that can be controlled via the SPI interface
• Register Monitor Interface via a UART Tx pin that can be useful when debugging the Arduino code
• 20 kB receive / transmit total buffer memory
• 4 independent multi-subnet sockets
• 20MHz SPI mode 0, 1, 2 or 3
• protocols: ARP, IPv4, ICMP, UDP, TCP, DHCP
• PING reply algorithm
• Interrupt System
• IP101GR PHY with Auto MDI-X capability
• microSD socket on board
• 3.3 - 5V compatible
