PINOUTs
There are 11 total active signal pins including power and ground for both MODULEs and RFDANTs. The MODULEs
have 7 additional ground pins. Also the MODULES have one extra pin for a total of 19 pins, this is pin 11, which
applies only to the RFD21735 which is for external antenna, however the RFD21733 pin 11 is a no-connect since it
has a built-in antenna.

There are a total of 8 ground pins, you only need
just one ground pin for an electrical connection to
make the module function. The additional ground
pins are for convenience and also performance
with layout configurations. The pin 12, 10 and 9
are recommended to always be connected since
they help provide some ground area for the
module as well as on the opposing side of the
antenna. However just one single ground out any
of the 8 GND pins are adequate for proper
function.

The black wire (ground) is pin #1, the red wire (+V)
is pin #2, and so on. See pinout on left side.
