MKR 1000 WiFi

End of Life

The Arduino MKR 1000 WiFi is the easiest point of entry to basic IoT and pico-network application design. Whether you are looking at setting up a sensor network for your office or building a smart home, the MKR 1000 WiFi will make that journey easy.

GET STARTED

Main Features

The MKR 1000 WiFi is a great choice for any beginner, maker or professional to get started with Internet of Things (IoT). Using the popular Arm® Cortex®-M0 32-bit SAMD21 processor, it also features the and the ECC508 crypto-chip for security. The board is part of the MKR family, where you can choose from a large variety of shields to build projects out of the box with minimal effort!

Wi-Fi

This Wi-Fi module from Atmel is part of the SmartConnect family, with focus on power consumption and power saving modes.

Tech Specs

Here you will find the technical specifications for the Arduino MKR 1000 WiFi.

Please read: operating voltage is 3.3V

The microcontroller on the this board runs at 3.3V, which means that you must never apply more than 3.3V to its Digital and Analog pins. Care must be taken when connecting sensors and actuators to assure that this limit of 3.3V is never exceeded. Connecting higher voltage signals, like the 5V commonly used with the other Arduino boards, will damage the board.

Please read: black conductive foam

You should remove the black conductive foam from the board pins before usage. If you don't remove it, the board may behave erratically.
