Arduino is compatible with NRF24L01 (it has mosi , miso , sck ,csn , ce pins) ... Is tinyDuino  compatible with NRF24 ..
( are there any csn ,  ce pins  on tinyduino ....or any equivalent pins . )

The CSN and CE pins can be connected to any digital output from the TinyDuino processor, so you can definitely hook this up to a TinyDuino.

Thanks,
