Mini 7-Segment Common Cathode
User Manual
Description
The MR-MINI-7SEG-CC is a common
cathode 7-segment with integrated on-board
current limited resistors. It is 10-PIN

ready. It can be plug directly
onto 10-PIN MRconnect

connector. User
can interface the signal from I/O pins of any
microcontroller to the connector on the
bottom of the module. Figure 1shown the
bottom view of the connector.
The module can be interface by connect the
common pin to GND and pin a-dp to 8-bit I/O
pins of any microcontroller. A segment can
be light up by sending logic HIGH to the
display. It is easier to decode if user
interface I/O pin of microcontroller as same
as 7-segment’s pin arrangement. PCB size
is 1.20” x 0.90”
