Daughterboard extension connectors CN5 and CN6

Two 60-pin male headers CN5 and CN6 can be used to connect a daughterboard or the
standard wrapping board to the STM32F779I-EVAL evaluation board. All GPIOs are
dispatched on memory connectors (CN10 and CN11), and on connectors CN5 and CN6.
The space between these two connectors is defined as a standard which allows developing
common daughterboards for several ST evaluation boards. The standard width between
CN5 pin 1 and CN6 pin 1 is 2700mils (68.58mm).
Each pin on CN5 and CN6 can be used by a daughterboard after disconnecting it from the
corresponding function block on the STM32F779I-EVAL evaluation board. For more details
refer to Table 21
