Power connector (CN12)

Your STM32L152-EVAL evaluation board can be powered from a DC 5 V power supply via
the external power supply jack (CN12) shown in
positive.

Daughterboard extension connectors (CN6 and CN7)

Two 50-pin male headers CN6 and CN7 can connect a daughterboard or standard wrapping
board to the STM32L152-EVAL evaluation board. All GPIOs are available on it. The space
between these two connectors and position of power, GND and RESET pins are defined as
a standard which allows common daughterboards to be developed for several evaluation
boards. The standard width between CN6 pin1 and CN7 pin1 is 2700 mils (68.58 mm). This
standard is implemented on the majority of evaluation boards.
Each pin on CN6 and CN7 can be used by a daughterboard after disconnecting it from the
corresponding function block on the STM32L152-EVAL evaluation board. Please refer to
Table 15 and Table 16 for details.
