Arduino introduced the MKR family and form factor to address IoT use cases by focusing on a standard blue print including a hardware crypto chip for enhanced security, a LiPo charger for power management, and an ARM Cortex M0 microcontroller.

The MKR family offers a  range of connectivity options, from low power long range to more traditional options, to satisfy the most stringent user requirements for IoT applications.

One of the boards released is the MKR WIFI 1010, ( https://store.arduino.cc/arduino-mkr-wifi-1010 ) a Cortex M0-based board that provides Wi‑Fi connectivity to IoT projects. With a highly optimized design it integrates the globally certified u‑blox NINA‑W102 ( https://www.u-blox.com/product/nina-w10-series ) stand-alone multi-radio module delivering Wi‑Fi and Bluetooth connectivity. Featuring an open CPU, the NINA‑W102 allows Arduino to run their own application right on the module, offloading communication tasks from the user-programmable Arduino CPU and increasing the board’s power efficiency.

Two more new boards incorporate the u-blox NINA-W102. The MKR Vidor 4000 ( https://store.arduino.cc/arduino-vidor-4000) is the first-ever Arduino board featuring an FPGA (field-programmable gate array) chip coupled with an innovative development environment, which aims to democratize and radically simplify access to the world of FPGAs. The Uno WiFi Rev 2 ( https://store.arduino.cc/arduino-uno-wifi-rev2 ) aims at making it easier to deploy products that need Wi-Fi connectivity.

In addition Arduino expanded its cellular offering with the MKR NB 1500, ( https://store.arduino.cc/arduino-mkr-nb-1500 ) which hosts a u‑blox SARA‑R410M ( https://www.u-blox.com/product/sara-r4n4-series) cellular module providing LTE Cat NB1 and LTE-M cellular connectivity that is pre-certified for global use. Also equipped with an ARM Cortex M0 microcontroller, the MKR NB 1500 is fully geared towards IoT applications with low demands for bandwidth and data volumes and is optimized for ultra-low power consumption, enabling highly efficient battery-powered applications.

The new boards feature industrial grade communication modules with an extended temperature range and superior guaranteed reliability, making them attractive to professional users seeking to develop small volume products or prototype new concepts and ideas.
