NINA W-10 Connections

Hello,

I would like to interface the NINA W-10 Wifi and Bluetooth module with an Atsamd21. However, when I examine existing arduino boards with this module and chip, there are multiple connections that overlap.

All I need is for the module to be able to communicate to the atsamd21 with existing arduino libraries. I don't need to do any other of the functions like update firmware, etc.

Out of the three serial communication connection (UART, SPI, I2c), which ones do I truly need?

Thank you

Also, could you please explain what each one does?

Also, I need both wiif and bluetooth to work.
