I'm excited to see the new support for an SPI-connected Ethernet solution (DM9051) described in the 4.0-beta1 release notes: https://github.com/espressif/esp-idf/re ... v4.0-beta1

I assume it will cut down the required IO pins from 9 (RMII) to 4 (SPI). I'm currently using the LAN8720 but I'm out of IO pins which I desperately need for other features.

Does anyone have an example schematic and evaluation board yet which incorporates the DM9051?

Anyone?
I've also come across the Microchip ENC28J60 solution which is being used in the Arduino community. It is only 10Mb vs. DM9051 10/100Mb. Will the speed decrease (from my current LAN8720) be noticeable with my simple web-server based on libesphttpd?

The schematic of the ENC28J60-based EtherCard shield is here:

This repo shows the ENC28J60 connections between the Ethercard and ESP32:

I see there is an availability problem for the DM9051, there are no US distributors carrying it. Just one Chinese distributor showing up on Octopart:

I second this request. Any engineers at espressif know where dm9051 dev boards can be purchased? I did find this schematic: https://www.dacomwest.de/images/Dateien ... o_v2.1.pdf

I found this note that discourages use of enc28j60 - https://github.com/espressif/esp-idf/bl ... md?plain=1

It looks like (for now) the W5500 has the best cost and availability in the US. ~$2 https://octopart.com/w5500-wiznet-30858120?r=sp
