Mouser stocks up on natively enabled IoT board

Distributor Mouser Electronics is now shipping the Uno WiFi Rev 2 from Arduino. The first AVR-based, natively enabled Internet of Things (IoT) board from Arduino, integrates an 8-bit microcontroller, wi-fi module, sensors and hardware-based security in the familiar Uno Rev 3 form factor. The new board addresses the wireless connectivity and low power demands of the growing IoT market.

The Arduino Uno WiFi Rev 2 is based on the new Microchip Technology ATmega4809 megaAVR microcontroller. The ATmega4809 offers core independent peripherals (CIPs) and an integrated high-speed analogue-to-digital converter (ADC) with voltage reference for faster conversion of analogue signals. The microcontroller also provides more memory than on previous Uno boards, with 48kBytes of flash and 6 kBytes of RAM, plus three UARTs to enable communication with more than one RF module.

This new board includes a u-blox NINA-W13 module with integrated TCP/IP protocol stack to provide 802.11b/g/n Wi-Fi connectivity enabling access to a wi-fi network or for use as an access point.

The board also features support for over-the-air programming for transfer of Arduino sketches or wi-fi firmware. Wireless security is provided by a Microchip ECC608 CryptoAuthentication IC, which combines hardware-based key storage with hardware cryptographic accelerators to implement authentication and encryption protocols.

Other features include onboard debugging, inertial measurement unit with 3-axis accelerometer and 3-axis gyroscope, 14 digital input/output pins (six PWM outputs), and six analogue inputs.

Designed to ease deployment of designs that need wi-fi connectivity, the Arduino Uno WiFi Rev 2 suits prototyping IoT applications such as smart agriculture, smart home, motor control, automation, wearables, and other open source projects.

Mouser stocks the latest semiconductors and electronic components and advanced search methods on its website helps customers quickly locate inventory. also houses data sheets, supplier-specific reference designs, application notes, technical design information and engineering tools.
