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.
