Overview
Through it, you can control a circuit of high voltage with low voltage, say 5V on the controller. There is an indicator LED on the board, which will light up when the controlled terminals get closed.

By popular demand, we are pleased to announce that it’s now possible to buy the Arduino MKR IoT Carrier. Originally forming a key part of the Arduino Oplá IoT Kit, we’ve responded to our community to make the carrier available on its own, thus enabling you to benefit from having a bunch of sensors, actuators, and a display all featured on the one board — making it quicker and easier to take your IoT projects to the next level. Featuring a large set of built-in sensors and actuators as well as a useful color display, the carrier lets you focus on prototyping your IoT ideas right away by saving on the hassle of wiring and soldering these components. The carrier can become a WiFi, LoRa, NB-IoT or GSM-compatible device by seamlessly connecting to any MKR family board. Building a user interface for these boards is easy with the embedded color OLED screen, five capacitive touch buttons, and the five RGB LEDs. The integrated sensors (temperature, humidity, pressure, RGBC light, gesture and proximity) allow you to map the environment around the carrier, and should you need to capture any other data there are over 100 additional Grove sensors that can easily be connected directly to the carrier. Here’s are quick demo of the carrier's capabilities! (Special shout out to Mirko Pacioni and Filo Connesso for creating this demo.) Capture and store all the data locally on an SD card, or connect your MKR family board to the IoT Cloud for real-time data captured, storage, and visualization.
