ESP8266 Community Forum

I've used both EthernetENC and the older UIPEthernet libraries with the ENC28J60 module on ESP8266 (a D1 mini clone).

EthernetENC is nice in that you just change the include in the existing Ethernet examples to EthernetENC.h and they work.

Thanks for the work on these libraries, @JurajA

for esp8266 I recommend the lwIP_enc28j60 library bundled with the esp8266 arduino core v 3
