not always connected. However, all the connected pins follow the defined pin-out described in 
. The extension headers can be used to connect a wide variety of Xplained Pro
extensions to Xplained Pro MCU boards and to access the pins of the target MCU on Xplained Pro MCU board
directly.

Xplained Pro segment LCD extension connector
Xplained Pro MCU boards that have a microcontroller that supports segment LCDs contain a 51-pin segment
LCD extension connector. This connector is implemented with HIROSEs DF-9 series. Xplained Pro MCU
boards use the male version DF9-51P-1V(69) and Xplained Pro extension boards use the female counterpart
DF9-51S-1V(69). This header has a standardized pin-out as shown in 
Note
All pins are not connected on all Xplained Pro MCU boards. How many pins that are used depend
on how many segments and common terminals the target MCU supports.
