Pin Header Connector (X1 to X4)

Over the pin header connector you can connect “directly” to the microcontroller. These contacts are like those on the ARDUINO board at a 5V level. You can use these pins freely to connect additional modules and electronics.

INFO: These pin header pins will change their state together with the Relays, digital inputs and outputs with the same labeling but on 5V level.

These pins are ESD protected.
