It is on the outer edge of the module neer the ribbon cable connector.
Its exact location is indicated by a circle with a + sign to indicate
the polarity.

I simply (temporary) soldered to the connector at the end of the ribbon
cable (not on the PCB) You see the ribbon cable goes into the module and
is then anchored by pushing down to fuse the connector. The other end
has a female PCB mountable header which I soldered to temporarily.
The pins on the connector are staggered thus making it impossible to
use with a breadboard breadboard. Just strip and solder some ribbon cable
from a PC I/O cable to the connector and then to some male headers. EASY.

I strongly suggest you DO NOT solder to the ribbon cable. This could
destroy the cable.
