What you do
- Soft-mount the Pixhawk 6X Mini on the UL8 stack (30.5 mm).
- Put PM02D in the power path (6S → PM02D → POWER1); do not use an analog PM on this FC.
- Split battery power in parallel to the Pacer (motors) and PM02D (FC); PM02D is not a PDB.
- Solder the low-ESR capacitor on the ESC power pads (included with the Pacer; PM02D has none). For 8″/6S prefer ~2200 µF or 2×1000 µF @ 35–50 V — Oscar Liang.
- Use the Mini cable set for I/O; reserve ports per the locked port table.
- Check polarity, connectors, and strain relief.
- First boot without props: FC starts, buzzer/LED OK, no shorts.

Done when
- FC has stable power via PM02D, wiring is tidy, and port allocation is locked.
