Daughterboard extension connectors CN6 and CN7
Two 52-pin male headers CN6 and CN7 are used to connect with daughterboard or
standard wrapping board to the STM32091C-EVAL evaluation board. All GPIOs are
available on it. The space between these two connectors, position of power, GND and
RESET pin are defined as a standard which allows developing common daughterboards for
several STM32 evaluation boards. The standard width between CN6 pin 1 and CN7 pin 1 is
2700 mils (68.58 mm). Most of evaluation boards implement this standard.
Each pin on CN6 and CN7 can be used by a daughterboard after disconnecting it from the
corresponding function block on the STM32091C-EVAL evaluation board. Refer to Table 22
and Table 23 for details.
