What is it

This is a Wizznet W5500 SPI Ethernet module that can be used with Sonocotta ESP32 Audio boards. For the ESP32-specific pinout, refer to the board documentation and the silkscreen hints on the board.

Features

• Supports the following Hardwired TCP/IP Protocols: TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE
• Supports 8 independent sockets simultaneously
• Supports Power down mode
• Supports Wake on LAN over UDP
• Supports High Speed Serial Peripheral Interface(SPI MODE 0, 3)
• Internal 32Kbytes Memory for Tx/Rx Buffers
• 10BaseT/100BaseTX Ethernet PHY embedded
• Support Auto Negotiation (Full and half duplex, 10 and 100-based)
• 3.3V operation with 5V I/O signal tolerance
• LED outputs (Full/Half duplex, Link, Speed, Active)

Practical Observations

Every ESP32 audio board has a header that allows for installing a W5500 SPI Ethernet module, which is very easy to set up and configure. The only downside is that with the module installed, the board will not fit the case, unless it is cut to accommodate extra height.
