sions to Xplained Pro MCU boards and to access the pins of the target MCU on Xplained Pro MCU board di-
rectly.

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
extension connector
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.
