FlyingRC 5A 6S BEC Step-down Module
A small step-down power module. It converts a higher battery voltage into a regulated lower voltage for receivers, flight-controller accessories, servos, video equipment, or other onboard electronics.
Best used for
- 2-6S LiPo aircraft electronics needing 5 V, 6.2 V, 7.4 V, or 9 V power.
- Small builds where an external BEC is safer or cleaner than drawing power from the flight controller.
- Users who need selectable output voltage through solder jumpers.
Key features
- Uses MonolithicPower MP9447 buck converter.
- Selectable output voltage: default 5 V, with solder-jumper options for 6.2 V, 7.4 V, and 9 V.
- Designed as a compact, high-performance BEC module.
Setup / wiring notes
- Solder the included capacitor with correct polarity; long lead is positive and short lead is negative.
- Input voltage must be at least about 0.8 V higher than the selected output voltage.
- Default output is 5 V when no jumper pad is bridged.
Check before use
- Do not reverse capacitor polarity.
- Verify jumper voltage before connecting sensitive equipment.
Key specs
- MP9447 step-down BEC module
- 7-26 V / 2-6S LiPo input range
- Selectable 5 V, 6.2 V, 7.4 V, or 9 V output
