Daughter board extension connector CN3 and CN4

Two 44-pin male headers CN3 and CN4 can be used to connect the daughter board or a

standard wrapping board to STM8L1528-EVAL evaluation board. All GPIOs are available on

the connectors. The space between these two connectors and the position of power, GND

and RESET pins are defined as a standard which allows to develop common daughter

boards for several evaluation boards. The standard width between CN3 pin1 and CN4 pin1

is 2700mils (68.58mm). This standard has been implemented on most of the ST evaluation

boards.

Each pin on CN3 and CN4 can be used by a daughter board after disconnecting it from the

corresponding function block on STM8L1528-EVAL evaluation board. Please refer to

Table 15 and Table 16 for details.
