TUTORIAL: Pin Header Connector (X1 to X4)

Over the pinheader connector you can contact “directly” to the microcontroller. Theses contacts are like on the ARDUINO board at a 5V level. You can use this pins freely to connect additional modules and electronics.

INFO: This pinheader 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.
