Overview
With this carrier in combination with any board from the MKR family, you can quickly create your next IoT project without any extra components. This carrier has all you need in sensors and actuators to create cool projects connected to the Internet.
Using the MKR IoT Carrier Rev2 in combination with any board of the MKR family, you can quickly build:
- Environment monitoring stations: Using the sensors on the carrier, you can map different phenomena around you. You can easily measure temperature, humidity, barometric pressure and air quality or detect the movement of the board, and in case you want to expand the sensor you can use any of the grove connectors to connect analog or I2C grove compatible modules. All this information can be stored in the SD card or sent directly to the Arduino IoT Cloud.
- GUI IoT interface: Even if you want to visualize sensor data or design your own user interface, you can use the OLED color display to create your own navigation menus or use the LEDs and the buzzer for feedback.
- Control external devices: Control electronic appliances up to 24 Volts using the two on-board relays. Either you want to turn on or off your reading lamp remotely through the Arduino IoT Cloud Remote app or use any of the sensor data to affect the behavior of the lamp.

After becoming frustrated at his lack of archery skills and not wanting to spend an eternity practicing getting better, Shane Wighton (known as Stuff Made Here on YouTube) sought to build a rig that could automatically correct his aim for the perfect shot every time. The device is comprised of a rigid sleeve that fits over the wearer’s forearm, along with a pair of stepper motors that can adjust where the bow is pointing either vertically or horizontally via a rack-and-pinion. These motors are driven by an Adafruit microcontroller running CircuitPython and a couple of motor driver modules that provide the necessary current. But that's not all, he also created a small rig that uses an Arduino Uno and servo motor to autonomously fling targets into the air. Target tracking is achieved by having a set of eight OptiTrack cameras around the room monitor the space for tiny gray spheres, and through the use of a special triangulation algorithm, they can accurately determine where both the arrow is pointing and where the target is in 3D space. Initially, the system missed all of its shots due to poor software and the wrong kind of bow, so Wighton completely rewrote his program and switched to a compound bow instead. Once everything had been corrected, the software was able to predict where a flying target would end up according to its speed, and thus had the ability to intercept it. The Auto-Aiming Bow could also hit a target the size of a 3mm-wide circle with scary precision.
FAQs
What are the main differences between MKR IoT Carrier and MKR IoT Carrier Rev2?
Some sensors have changed between both versions:
- The humidity sensor (HTS221) and barometric pressure sensor (LP22HB) was replaced with the BME6688 sensor.
- The IMU (LSM6DS3) was replaced with LSM6DSOX.
Some other components have been repositioned:
- Addition of a reset button
- 90° rotation of the relay connectors
- Repositioning of the light sensor (APDS-9960)
- Change of pins assigned to control the relays to pin 1 and 2
- Change grove connector assignment from pin A5 to A6
Do I have to change my sketch if I have been using the first revision of the MKR IoT Carrier?
The MKR IoT Carrier library is compatible with both revisions of the carrier, just make sure to use the latest version of the library.
