Hello.
I have a KC868-A16 - Great board. I have a number of IR sensors that need to send back state via MQTT to different topics so have had to write custom sketch in Aurdino IDE.
Problem is the sensor never goes inactive. I have tested the IR with a meter and voltage drop on digital out when active and high when inactive.
KC868-A16 seems to be 12v on the input which is weird. Help please!
