📊 HUB75 vs HUB75E: Key Differences
| Feature | HUB75 | HUB75E |
|---|---|---|
| Address Lines | 4 lines (A, B, C, D) | 5 lines (E, A, B, C, D) |
| Pin 8 Function | Enable line (control signal) | Address line E (additional address) |
| Max Scan Mode | 1/16 scan (32 rows total) | 1/32 scan (64 rows total) |
