4.13 Extension connector CN12
The extension connector CN12 is a 2.54 mm pitch header located at the bottom side of the
STM32F469I-DISCO Discovery board. It is composed of 16 square pins of 0.64
mm
arranged in double row and it is compatible with usual connectors mating with 2.54
mm
headers, having 0.64
mm square posts. Pins 1, 2, 15 and 16 are marked on the silkscreen
of the PCB, pin 1 is signaled by a triangle as shown below:
