extension connectors CN12 and CN13
Two 50-pin male headers, CN12 and CN13, can be used to connect a daughterboard or
standard wrapping board to the STM3210B-EVAL board. A total of 80 GPIOs are available
on these connectors. Each pin on CN12 and CN13 can be used by a daughterboard after
disconnecting it from the corresponding function block on the STM3210B-EVAL board.
Refer to
