This Ethernet Shield is powered by a PIC32MX controller with an L2 three port network switch and a microSD connector. 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 PIC32MX695F512H with unique MAC address
• extra 8 + 14 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 host controller code
• 106 kB receive / transmit total buffer memory
• 16 independent multi-subnet sockets
• 20MHz SPI mode 0, 1, 2 or 3
• protocols: ARP, IPv4, ICMP, UDP, TCP, DHCP
• PING reply algorithm
• Interrupt System
• KSZ8863RLL L2 3 port managed network switch with access to all registers
• microSD socket on board
• 3.3 - 5V compatible
• SMPS for higher power efficiency
