TIAO Smart Sprinkler 16 Station Expansion Board Zone Expander

The TIAO Smart Sprinkler comes with 16 stations. However, if your system has more than 16 zones, then you need expansion boards.

Each expansion board has 16 stations, so if you need 32 stations, you need a TIAO Smart Sprinkler Controller and an expansion board.

This expansion board is compatible with Open Sprinkler Controller. However, this expansion board is NOT compatible with TIAO Smart Sprinkler Pi V1 or V2.
