Hello draufunddran,

The schematics of the Arduino Uno WiFi will be released once the product hits the market. Stay tuned for updates!

the new WiFi library was published for the Arduino MKR WiFi 1010, Arduino MKR VIDOR 4000 and Arduino UNO WiFi Rev.2.

for networking it uses SPI communication with the WiFi module and additional pins:
7 for SLAVEREADY  signal from the firmware
5 SLAVERESET  to reset the WiFi module
NINA_GPIO0 to put the WiFi module into flashing mode for firmware update

NINA_GPIO0 is not defined in the library. I assume it will be in pins_arduino.h

Serial1 of Atmega is connected to Serial of WiFi module for flashing the WiFi module over the Atmega, because the Atmega is connected to USB with UART0.

a version of SerialPassthrough sketch in Armega will be used for the firmware update over Serial. in setup() it will reset the WiFi module into flashing mode
