How many pins can I actually use for sensors?
Posted: 22 Jul 2019 06:29
I'm looking to plug in a lot of door sensors/reed switches so I just need binary input. Judging from the diagram that came in the box, it looks like pins 0-8 and 17-25 can all be used for this purpose, so I should be able to connect 18 binary sensors or switches to the board. Is that correct?
