Arduino Relays

Any Relay, Any Platform

We designed our boards to be instantly compatible with any platform. For Arduino we have shields that will give a simple plug in to connect to any of our IoT line of boards. All you have to do is add the adapter for your version of the Arduino as an add-on and you’re ready to go.

We have a full line of Arduino Relay options able to cover almost any application. Choose from high power relays, signal relays, mechanical relays, solid state relays, SPDT, DPDT, SPST, and more. NCD has been making relay controllers for more than 20 years. We know relays.

Arduino Micro Relays

Arduino Micro plugs into our Relay Controllers using a simple adapter available when you add an Arduino Relay to your cart. The adapter plugs directly into the Relay Controller and then plug your Arduino Micro into that. No soldering or running wires. You can also order the adapter separately.

Even if you’re an electronic engineer, using our Arduino Relay Controllers for your Relay Control project will speed up the process and let you focus on your application without worrying about the hardware.

Arduino Nano Relays

Arduino Nano plugs into our Relay Controllers using a simple adapter available when you add an Arduino Relay to your cart. The adapter plugs directly into the Relay Controller and then plug your Arduino Nano into that. No soldering or running wires. You can also order the adapter separately.

Even if you’re an electronic engineer, using our Arduino Relay Controllers for your Relay Control project will speed up the process and let you focus on your application without worrying about the hardware.

Arduino Due Relays

Arduino Due plugs into our Relay Controllers using a simple adapter available when you add an Arduino Relay to your cart. The adapter plugs into the Arduino Due and connects to the Relay Controller using an I2C cable. You can also order the adapter separately.

These Arduino Relays are expandable and easy to use so if you need additional relays or sensors you can just snap them on using the included I2C cable.

Even if you’re an electronic engineer, using our Arduino Relay Controllers for your Relay Control project will speed up the process and let you focus on your application without worrying about the hardware.

Arduino Uno Relays

Arduino Uno plugs into our Relay Controllers using a simple adapter available when you add an Arduino Relay to your cart. The adapter plugs into the Arduino Uno and connects to the Relay Controller using an I2C cable. You can also order the adapter separately.

These Arduino Relays are expandable and easy to use so if you need additional relays or sensors you can just snap them on using the included I2C cable.

Even if you’re an electronic engineer, using our Arduino Relay Controllers for your Relay Control project will speed up the process and let you focus on your application without worrying about the hardware.
