Description
Not sure about the following connections, please advise+ point out anything else
1) Judging by this connection to an Arduino board: http://jeelabs.org/2009/02/10/rfm12b-library-for-arduino/ (used for sending packets between modules)
It seems that only the SPI pins: SDO, SDI, nSEL and SCK are needed for communication with a microcontroller. so I've left pin 3-5 unconnected for both transmitter and ground station.
2) The interrupt, reset and interrupt request pins are active low, so I've used 4k7 resistors to pull them up to vcc.
