The MKR boards come with various connectivity modules ranging from WiFi to GSM, making them the right solution for your next IoT project. Compared to the Arduino Uno’s familiar form factor, MKR boards are much smaller. It combines a low-power ARM® Cortex® microcontroller with the possibility to be powered by a rechargeable LiPo battery using the built-in connector. Boards like Arduino MKR WiFi 1000, Arduino MKR ZERO, Arduino MKR WAN 1310, Arduino MKR FOX 1200, Arduino MKR NB 1500 are just some of the compatible development boards with the Arduino MKR footprint of this Click Shield.

This development platform provides users with an extremely easy and common way to combine the Arduino MKR footprint compatible development board with their favorite Click boards™ in their upcoming projects.

Note: Arduino MKR board is not included in the package.

Arduino MKR Click Shield comes equipped with two proprietary mikroBUS™ sockets, allowing all the Click board™ devices to be interfaced with the Arduino MKR board with no effort at all. This way, Mikroe allows its users to add any functionality from our ever-growing range of Click boards™, such as WiFi, GSM, GPS, Bluetooth, ZigBee, environmental sensors, LEDs, speech recognition, motor control, movement sensors, and many more. More than 1257 Click boards™, which can be stacked and integrated simply, and conveniently, are at your disposal.

The Arduino MKR can be programmed with the Arduino Software (IDE), an Integrated Development Environment common to all Arduino boards, and runs both online and offline. The main IC on the Arduino MKR board comes pre-burned with a bootloader that allows you to upload new code to it without an external hardware programmer. The Arduino software includes a serial monitor that allows sending simple textual data to and from the Arduino board. In addition, the MKR boards also supports I2C and SPI communication and includes a Wire library to simplify the use of the I2C bus. For more information on how to get started with the Arduino Software, visit the Getting Started page.

This Click Shield also has several switches that perform functions such as selection of the logic level of analog signals on mikroBUS™ sockets, as well as a selection of logic voltage levels of the mikroBUS™ sockets themselves. Besides, with the help of existing bidirectional level-shifting voltage translators the user can combine Arduino MKR board with any Click board™, regardless of whether the Click board™ operates at 3.3V or 5V logic voltage level.

Once you plug Arduino MKR board into the Arduino MKR Click Shield, it will allow you access to hundreds of Click boards™ working with 3.3V or 5V logic voltage level.
