Xplained Pro Segment LCD Connector
Xplained Pro MCU boards that have a microcontroller, which supports segment LCDs, can implement a
51-pin segment LCD extension connector. This connector is implemented with HIROSE 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). The connector has a standardized pin-out as shown in the table
below.
Info:
All pins are not connected on all Xplained Pro MCU boards, it depends on how many segments
and common terminals the target MCU supports.
Pin 37, 38, 39, 40, 41, and 42 can alternatively be used for QTouch signals. When they are
used for touch they should not be used for display segments.
