Daughterboard extension connectors (CN5 and CN6)

Two 60-pin male headers (CN5 and CN6) can be used to connect with a daughterboard or a standard wrapping
board to the STM32H7B3I-EVAL Evaluation board. All GPIOs are available on them and memory connectors
(CN12 and CN13).
The space between these two connectors is defined as a standard, which allows the development of common
daughterboards for several ST Evaluation boards. The standard width between CN6 pin1 and CN5 pin1 is
2700 mils (68.58 mm). Each pin on CN5 and CN6 can be used by a daughterboard after disconnecting it from the
corresponding function block on the STM32H7B3I-EVAL Evaluation board. Refer to
and Table 70 for details.
