New External Relays

When we developed the Aquaponics Controller we knew one important design characteristic would be the option of having external relays that are already assembled and enclosed for those uncomfortable with mains level wiring.  And not for nothing, but external relays also have the added benefit of being replaceable.

This board features a 20A, SPST-NO relay with traces (big traces) to match and a more intuitive 5V control logic than other external relay boards for the Arduino platform.

You can find this kit in our store.
