It is 10-PIN MRconnect 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. FIG 1: Bottom view pin out The module can be interface by connect the common pin to GND and pin a-dp to 8-bit I/O Name Type Description pins of any microcontroller. A segment can a, b, c, d, Input Segment input (send be light up by sending logic HIGH to the e, f, g, dp logic HIGH to light up display. It is easier to decode if user the segment) interface I/O pin of microcontroller as same GND PWR Supply ground as 7-segments pin arrangement. PCB size NC NC No connect is 1.20 x 0.90 Specifications: 10-PIN MRconnect ready +3.3 or +5VDC logic Onboard current limited resistors Small and compact in size Female header connector.
