![]() The ATmega4809 is a microcontroller featuring the 8-bit AVR® processor with hardware multiplier, running at up to 20 MHz and with up to 48 KB Flash, 6 KB SRAM, and 256 bytes of EEPROM in 48-pin packages. One useful feature of Uno Wi-Fi is support for over-the-air (OTA) programming, either for transfer of Arduino sketches or Wi-Fi firmware. The Wi-Fi module is a self-contained SoC with integrated TCP/IP protocol stack that can give access to a Wi-Fi network (or the device can act as an access point). It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. It has 14 digital input/output pins (of which six can be used as PWM outputs), six analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. The Wi-Fi connection is secured by the ECC608 crypto chip accelerator. The Arduino Uno Wi-Fi is functionally the same as an Arduino Uno Rev3 except it incorporates an 8-bit microprocessor from Microchip, it has an onboard inertial measurement unit (IMU), and users can connect it to a Wi-Fi network with the onboard Wi-Fi module.
