Daughter board extension connectors (CN6 and CN7)

Two 52-pin male headers, CN6 and CN7, can be used to connect with the daughter board or
standard wrapping board to the STM32303C-EVAL evaluation board. All GPIOs are
available on them.The space between these two connectors and the position of the power,
GND and RESET pins are defined as a standard which allows developing common
daughter boards for several evaluation boards. The standard width between CN6 pin1 and
CN7 pin1 is 2700mils (68.58 mm). This standard has been implemented on the majority of
the evaluation boards.
Each pin on CN6 and CN7 can be used by a daughter board after disconnecting it from the
corresponding function block on the STM32303C-EVAL evaluation board. For more details,
refer to Table 27
