7-Segment Display Map
Correctly wire your numerical displays. This guide shows the standard segment labeling (a through g) and the common pin configurations for both Common Anode and Common Cathode 7-segment LED modules.
| Segment | Standard Pin | Function |
|---|---|---|
| a | 7 | Top Horizontal |
| b | 6 | Top Right Vertical |
| c | 4 | Bottom Right Vertical |
| d | 2 | Bottom Horizontal |
| e | 1 | Bottom Left Vertical |
| f | 9 | Top Left Vertical |
| g | 10 | Middle Horizontal |
| DP | 5 | Decimal Point |
Common Anode displays require a Low (GND) signal to light up a segment, while Common Cathode displays require a High (VCC) signal.
