Daughterboard extension connector CN5 and CN10

Two 42-pin male headers CN5 and CN10 can connect the daughterboard (or standard
wrapping board) to the STM32L152D-EVAL evaluation board. All GPIOs are available on
them and the LCD glass connectors (CN6, CN7).
The space between these two connectors and positions 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 CN5 pin1 and CN10 pin1 is
2700 mils (68.58 mm). This standard has been implemented on the majority of evaluation
boards.
Each pin on CN5 and CN10 can be used by a daughterboard after disconnecting it from the
corresponding function block on the STM32L152D-EVAL evaluation board. Refer to
Table 22 and
Table 22.
