I/O
Status Lines. Each line can be configured
as either an input to register button or
contact closures or as an output to control
application circuitry.

GND — Ground
10 C0 I
This line sets the input/output direction for
status lines S0-S3. When low, the lines are
outputs; when high they are inputs. Do not
leave floating.
11 C1 I
This line sets the input/output direction for
status lines S4-S7. When low, the lines are
outputs; when high they are inputs. Do not
leave floating.
12 POWER_DOWN I
Power Down. Pulling this line low places the
module into a low-power state. The module
is not functional in this state. Pull high for
normal operation. Do not leave floating.

Pin Assignments
There are three version of the module. The standard version is the smallest.
The other versions have mostly the same pin assignments, but the antenna
is routed to either a castellation (-CAS) or a U.FL connector (-UFL),
depending on the part number ordered.
