Yes. That also means that if you get one board you can only use it with 6 of your zones. If you have more then 6 zones, you need multiple boards.
I personally have been using this GitHub - LXXero/DSCAlarm and this [OBSOLETE] DSC -> EVL-3(4) -> Alarmserver -> Smartthings with a raspberry pi. I can interact with the panel and it also integrates with SHM.
