IONI connector pinout
IONI card edge connector fits into a standard PCI-Express 8X socket connector.
Pinout
The pinout of IONI drive is provided in the following table.

| A5 | ANAIN- | B5 | ANAIN+ | |
| A6 | GPI1 | B6 | GPI2 | |
| A7 | GPI3 | B7 | GPI4 | |
| A8 | GPO1 | B8 | GPO2 | |
| A9 | GPO3 | B9 | GPO4 | |

- Power signals
| Pin | Signal name | Pin | Signal name | |
|---|---|---|---|---|
| A18-A22 | GND | B18 | Not connected | |
| A23 | Not connected | B19-B22 | HV+ | |
| A24-A27 | PHASE1 | B23 | Not connected | |
| A28 | Not connected | B24-B27 | PHASE2 | |
| A29-A37 | PHASE3 | B28 | Not connected | |
| A38 | Not connected | B29-B37 | PHASE4 | |
| A39-A43 | PHASE1 | B38 | Not connected | |
| A44 | Not connected | B39-B43 | PHASE2 | |
| A45-A49 | GND | B44 | Not connected | |
| B45-B49 | HV+ |
Note 1: pins marked as Not connected are left empty for to make larger clearance for high voltage signals. Leave these pins unconnected on motherboard designs.
Note 2: Each power signal is present in two pin groups (internally parallel) and these signals should be wired parallel on motherboard.
