Spi Transceiver module |

Hi, can you please recommend me a good low cost (spi) transceiver module for student project to use with a PIC16f88? |

SPI transceiver to what?.
At what speed?.
SPI is just standard logic lines. Any non inverting CMOS/TTL driver chip can be used as a transceiver. However if you want something that goes longer distances, or with better isolation, you have to decide 'what' you are going to use as the transport 'layer'. Fibre optic?. RS485?. Proprietary differential signalling?. Wireless?. etc. etc.. Cost, maximum speed, and distances supported change according to this....
If distances are more than a few feet, and speeds are high, 'think again' clock slews start to become significant, and SPI is not then the best interface to choose.

Thanks for your reply.
I mean a wireless RF Transceiver. I would like to establish a wireless communication between several pics.
The pic should be connected to the RF module through SPI as I'm already using USART (TX and RX) for PC connectivity.
Distance: 10 to 20 meters.
The speed doesn't matter. |
