Arduino announces Uno WiFi Rev 2 with ATmega4809 MCU

Arduino announced Uno WiFi Rev 2, the company’s first AVR-based, natively-enabled IoT board. This new addition to the Arduino product family will address the demand of the growing IoT market, especially in need of wireless connectivity and low power requirements.

Arduino Uno WiFi Rev 2 includes a new enhanced AVR microcontroller from Microchip, making it even easier to deploy products that need connectivity using the Uno R3 classic form factor. Uno WiFi Rev 2 is ideal for emerging IoT industries, including automotive, agriculture, consumer electronics, smart home, and wearables. The WiFi connectivity is powered by u-blox.

The Uno WiFi Rev 2 board features Microchip’s ATmega4809 8-bit microcontroller bringing improved security, flexibility and reliability. As the first megaAVR device to feature Core Independent Peripherals (CIPs), the ATmega4809 includes an integrated high-speed Analog-to-Digital Converter (ADC) that enables faster conversion of analog signals, resulting in more accurate external measurement of temperature, motion and light levels. It also provides more RAM (6KB), Flash (48K) and 3 UARTS. Combined with Microchip’s ATECC608 CryptoAuthentication device on the Uno board, the ATmega4809 provides hardware-based security for connecting projects to the cloud including AWS and Google.

Key Uno WiFi features include:

• Advanced debugging ability
• The ability to communicate with more than one RF module using UARTS
• Peripheral multiplexing functions of mega4809 give project developers the ability to move peripherals around to other pins to avoid conflicts
• Cryptographic coprocessor with secure hardware-based key storage
• Improved peripherals including an analog-to-digital converter that provides more accurate measurement sensors
• Industrial level security allowing each UNO WiFi board to be uniquely identified and protected when connected to the cloud

The Uno WiFi Rev 2 is available for purchase at store.arduino.cc from the end of June, 2018.
