9.6 Daughterboard
extension connector CN6 and CN7
Two 60-pin male headers CN6 and CN7 can be used to connect a daughterboard or a
standard wrapping board to the STM32H743I-EVAL Evaluation board. All GPI/Os are
available on CN6 and CN7 and memory connectors on CN11 and CN12.
The space between these two connectors is defined as a standard that allows developing
common daughterboards for several ST evaluation boards. The standard width between
CN6 pin1 and CN7 pin1 is 2700 mils (68.58 mm).
Each pin on CN6 and CN7 can be used by a daughterboard after disconnecting it from the
corresponding function block on STM32H743I-EVAL Evaluation board. For details refer to
Table 21
