Onion Relay Expansion [Discontinued] Chip Family_STM The buzzer is controlled byThe Relay Expansion enables your Omega to control two other, independent electrical circuits. The circuits are isolated from the Omega and can operate at much higher or lower voltages than the Omega. So you can control other circuits youve built or small household appliances rated up to 60W. This Expansion is perfect for home automation projects since it gives you the ability to control other devices remotely using your Omega. It features two
