Arduino UNO WiFi Rev2 Developer Board

The Arduino UNO WiFi Rev2 Developer Board is an electronic component. Main ratings: Microcontroller ATMega 4809; Architecture AVR; Operating Voltage 5V; Flash Memory 48 KB. This page brings together the Arduino UNO WiFi Rev2 Developer Board pinout and key specifications, with the full datasheet PDF to preview below or download.

Arduino UNO WiFi Rev2 Module is a self-contained SoC (system on chip) with an 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 core of the Arduino Uno WiFi Rev2 is an ATmega4809, the ATmega4809 is a microcontroller featuring the 8-bit AVR® processor with a 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. The series uses the latest Core Independent Peripherals (CIPs) with low-power features, including an Event System, intelligent analogue, and advanced peripherals.

The Arduino Uno WiFi Rev2 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. The Wi-Fi connection is secured by the ECC608 crypto chip accelerator. 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.
