# ESP8266 I/O shield #
Main board for inputs and outputs multi IO for for exemple central heating system with FET outputs, relais outputs and 1-wire connection.
Need an ESP 8266 devboard.
On board 5V and 3.3V from 12 to 24V input.
Used this before making the one with ESP32 and more I/O and calculation power.
Works fine for many uses.
