Arduino® Uno WiFi Rev2

Uno WiFi 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.Product Overview 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. It supports OTA (over-the-air) programming, either for transfer of Arduino sketches or Wi-Fi firmware.
The Arduino Uno WiFi has 14 digital input/output pins—6 can be used as PWM outputs—6 analog inputs, a 16 MHz ceramic resonator, 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 or battery to get started.Technical specifications Microcontroller ATMEGA4809 Operating Voltage 5V Input Voltage (recommended) 7 - 12V Input Voltage (limit) 6 - 20V Digital I/O Pins 14 — 6 Provide PWM Output PWM Digital I/O Pins 6 Analog Input Pins 6 DC Current per I/O Pin 20 mA DC Current for 3.3V Pin 50 mA Flash Memory 48 KB (ATMEGA4809) SRAM 6,144 KB (ATMEGA4809) EEPROM 256 Bytes (ATMEGA4809) Clock Speed 16 MHz LED_BUILTIN 13 Length 68.6 mm Width 53.4 mm Weight 25 g
