PDN pin of 433 MhzTransmitter and 433Mhz Reciever

Hi,

I left the PDN of the transmitter and receiver unconnected... When PDN is power down will place the transmitter/receiver into a low-current state. The module will not be able to transmit/receive a signal. May I know where should I connect the PDN to ? Should I connect the PDN to the Vdd ? Thank you.

Regards.

All components bought from Parallax.

    Just leave it unconeccted. The PDN is pulled high internally, so no need for an external pullup to VDD.
