Arduino opens up WiFi and narrowband IoT

May 14, 2018 // By Julien Happich
Arduino has launched two new wireless connectivity boards to help streamline Internet of Things (IoT) development, namely the WiFi-enabled MKR WiFi 1010 board and the MKR NB 1500 narrowband IoT-enabled unit.

The MKR WiFi 1010 board is an evolution of the existing Arduino MKR1000, but now comes equipped with an ESP32-based module manufactured by u-blox. This key element delivers 2.4GHz WiFi and Bluetooth communications capability, along with leading RF and power performance: the ESP32 is a highly flexible device that provides adjustable power output, enabling optimal trade-offs between communication range, data rate and power consumption.
It uses open-source WiFi firmware, which makes it easy to reprogram for upgrading or to repair any security flaws. A significant feature is the MKR1010’s two standalone programmable processors – the first based on ARM processor core technology, the second based on a dual-core Espressif IC – making the board a high-performance solution that can distribute its workload across its dual-processor system. A secure authentication module, Microchip’s ECC508, uses crypto authentication to secure TLS network communications and connections.
The MKR NB 1500 employs the low-power NB-IoT (narrowband IoT) standard, designed to work over cellular/LTE networks. It is suitable for applications in remote areas such as on- field monitoring systems and remote-controlled LTE-enabled modules. Designed for global deployment, it supports transmissions via AT&T, T-Mobile USA, Telstra, Verizon over the Cat M1/NB1 deployed bands 2, 3, 4, 5, 8, 12, 13, 20 and 28. Both boards are fully compatible with the Arduino Uno, Mega and existing MKR boards. Also common to both boards is their MKR footprint, as well as the same wide range of available interfaces, including I2S, I2C, UART and SPI. Both boards also operate at 3.3V and offer input/output options including 22 digital I/Os – 12 with PWM outputs – and seven analog inputs.
