User Manual
Description
The MR-MINI-7SEG-CA is a common anode
7-segment with integrated on-board current
limited resistors. It is 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 VCC and pin a-dp to 8-bit I/O
pins of any microcontroller. A segment can
be light up by sending logic LOW 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”
