Thank you for the quick reply,If I use the serial LCD, I can connect the Ethernet W5100 + nRF24L01 together?

One in hardware but it's a bus... you just need a different CS pin for each device... Or you can bitbang the spi data in software and make as many as you like.Doc
OK, So why Maga 2560 is better than arduino uno ?or this project? Because he has more devices pins?
I see, thank you Are all unused digital pin can be used as the CS pin?
Are there Cons connecting multiple devices to SPI?
Which limit the amount of devices that can be connected to SPI? Depending on the amount of available digital pins the controller?
