Introducing the New MKR IoT Carrier Rev2: Time to Start Your Next IoT Project

If you're looking for an ever faster, smoother and more rewarding way to create your own IoT projects at home, the new MKR IoT Carrier Rev2 might be perfect for you.

The new bracket can work with any board in the MKR family, giving you a wide choice of connectivity options to meet the needs of your next IoT project. The MKR IoT Carrier Rev2 doesn't require any additional components to get started, so you can create impressive, complete projects without hassle.

What does the carrier include? You will get all the sensors and actuators you need to develop IoT projects and connect them to the internet, taking your home automation journey to the next level.

Let's take a look at what you can build with the MKR IoT Carrier Rev2 and any board in the MKR family.

Environmental monitoring stations. The new carrier comes with sensors that allow you to map and measure various things in the world around you: temperature, humidity, air quality, barometric pressure, and more. You can also follow the movement of the board. For even more sensory perception, you can connect analog or I2C-compatible Grove modules to the Grove connectors. You can store the data you collect on the SD card or send it directly to the Arduino IoT Cloud. Graphical IoT interface. Viewing your data is hugely important - and the Rev2 comes with its own color OLED display, allowing you to create your own navigation menus. You can also use the included LEDs and buzzer for feedback. Connect and control external devices. IoT is all about networking, and with the Rev2 you can control electronic devices up to 24 volts using the two built-in relays. You can do this manually, such as turning your reading lamp on or off through the Arduino IoT Cloud Remote app, or you can set the lamp to behave based on sensor data, such as light levels in the piece.

The MKR IoT Carrier vs the MKR IoT Carrier Rev2 - what's the difference?

There are a few key differences between Rev2 and the previous version of the MKR IoT Carrier. Here are the main ones.

Some sensors have changed:

The humidity sensor (HTS221) and the barometric pressure sensor (LP22HB) have been replaced by the BME6688 sensor. The IMU (LSM6DS3) has been replaced by LSM6DSOX.

Based on customer feedback, other components have been repositioned:

Added a handy reset button 90° rotation of the relay connectors Repositioning the light sensor (APDS-9960) Changed the pins assigned to control the relays at pins 1 and 2 Change slot connector assignment from pin A5 to A6 Should I modify my sketch if I used the first revision of the MKR IoT Carrier?

No, the MKR IoT C...
