Arduino Uno WiFi Rev2
Add WiFi to your devices with the Arduino Uno WiFi. It’s basically an Arduino Uno Rev3 with more kick: It comes with a brand new 8-bit microprocessor from Microchip, and an onboard IMU (Inertial Measurement Unit). As for the WiFi connection, that’s made secure with the new ECC608 crypto chip accelerator.
Add this board to a device and you’ll be able to connect it to a WiFi network, using its secure ECC608 crypto chip accelerator. The Arduino Uno WiFi is functionally the same as the Arduino Uno Rev3, but with the addition of WiFi and some other enhancements. It incorporates a brand new 8-bit microprocessor from Microchip and has an onboard IMU (Inertial Measurement Unit).
The Wi-Fi Module is a self-contained SoC with integrated TCP/IP protocol stack that can provide access to a Wi-Fi network, or act as an access point.
The Arduino Uno WiFi has 14 digital input/output pins—5 can be used as PWM outputs with Pin 11 that is not PWM as on the UNO Rev3 —6 analog inputs, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller. Simply connect it to a computer with a USB cable or power it with an AC adapter to get started.
