Hi,
I am working on a project where I need to interface two SPI modules with Arduino UNO. I have already designed the project and now supervisor wants to add a new SPI module in the project, so can we do that or do I have to change the board.
Currently, I am using Arduino UNO and I have searched online but couldn't find any Arduino board having 2 SPI ports. So, if there's any such board please mention it out.
Thanks.

Re: Interfacing of two SPI modules with Arduino UNO
SPI is a bus, so it can support multiple devices. The devices can share the MISO, MOSI and SCK signals. Each will need its own CS pin.
