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.
