Choose the correct version corresponding to your main controller:

• OS v3 → Expander v3 (AC / DC depending on your main controller version).
• OS v2 → Expander v2.1 (AC / DC depending on your main controller version).
• OpenSprinkler Pi (OSPi) → Expander 2.1 AC (OSPi only has AC version).

Different expander versions come with different expansion cables, and cannot be plugged into each other: Expander v2.1 comes with a 2×4 wire cable and polarized connector; Expander v3 comes with a 2×5 ribbon cable and IDC connector.

Choose AC/DC:

• AC model has an orange-terminal or red-receptacle
• DC model has a black-receptacle or USB-C connector
• There is NO expander for Latch model. DC expander will NOT work with Latch.
• You can also find out the power version when you reboot the controller, or check the ‘About’ page in the mobile app or web interface.
