ESP32 Ethernet Module for OpenEVSE / EmonEVSE.


This module will be pre-loaded with ESP32 firmware V4.x and wiring harness attached ready as a drop-in replacement for the WiFi gateway modules used on OpenEVSE / EmonEVSE units. 

When ordering please specify if your have controller V5 (black pin-header connections) or V5.5 (white JST connectors). 


Note: This module also supports WiFi connection, but if only a WiFi connection is required a more economic option would be to choose the non Ethernet WiFi gateway module.
