It should be noted that GPIO lines 8-15 can be used for any desired I/O purpose,
not just to control a wireless add-on board. You can use this connector for your
own control purposes.
Main and Backup Power
The power jack of the EM1206EV accepts "small" power connectors, 3.5mm in
diameter. Use APR-P0011, APR-P0012, or APR-P0013 power adaptor supplied by
Tibbo or a similar adaptor with 12V nominal output voltage. Adaptor current rating
should be at least 500mA. On the power jack, the ground is "on the outside", as
shown on the figure below.
Alternatively, you can power the board through the Vin line on the expansion
connector. Two onboard diodes combine power jack and Vin inputs into a single line,
which goes to the switching regulator. Clean 3.3V output produced by the regulator
is used to power the EM1206EV board itself, the EM1206 module, and optionally an
add-on board plugged into the wireless add-on connector. This 3.3V power is
available on the expansion connector as well.
The following drawing illustrates this power arrangement:
