Arduino MKR WiFi 1010

In this modern world, people are talking about IOT devices alot – the idea that most of your devices at home such as light bulbs, fans, refrigerators, printers, TVs are going to be intelligent and are going to be able to connect to internet. Arduino boards are one of the way you can go about building your own IOT devices. Arduino has now released two new IOT boards – Arduino MKR WiFi 1010 and MKR NB 1500.

Arduino MKR WiFi 1010

The MKR WIFI 1010 is an upgraded version of the MKR1000, Arduino MKR1000  which was designed as a practical and cheap alternative for hobbyists who want to add WiFi connectivity to their projects with ease.

Arduino MKR WiFi 1010 has an ESP32 module which is made by U BLOX that can provide high speed  network connectivity and simplifying the complex design of IOT projects incorporating WiFi Connectivity.

This board is powered by SAMD21 Cortex M0 and 32bit low power ARM MCU with a U BLOX NINA-W10 Series WiFi chip set supporting IEEE 802.11 b g n with ECC508 Crypto Authentication.

This board has an awesome 32-bit architecture and more refined power consumption mechanisms which improves overall performance with less power consumption and better monitoring and control over the temperature variations of the board during run time.

Like other Arduino boards this board have a wide set of GPIO pins – Digital as well as analog that support I2C, PWM, UART, SPI etc and can be programmed online or offline using Arduino IDE.


Input voltage to this board should be 5V for stable operation. In this board, an optional LiPo battery can be connected which will be automatically switched when one fails. This board can also be powered using USB cable via USB port (5V).

Note: While other Arduino board that takes input and gives output a maximum of 5 V, this GPIO pins this board can handle a maximum of 3.3V only. The board may burn off if you provide a voltage greater than 3.3V with out using level shifting circuits.
