Flywoo 3.3V 1.5A BEC Module

The Flywoo 3.3V BEC module is a compact step-down voltage regulator designed to deliver clean, consistent power to sensitive 3.3V electronics on your drone. With a robust 1.5A continuous output, it provides ample headroom for powering 3.3V radio receivers (such as specific Spektrum satellites or older ELRS hardware), micro GPS units, and external sensors. It also serves as a crucial repair component for drone builders: if your flight controller's onboard 3.3V LDO regulator burns out—a common issue that kills power to the MCU or receiver—wiring in this external BEC can bypass the dead component and restore the board to full working order without requiring a complete replacement.

Key features

• Delivers a stable 3.3V step-down output for sensitive FPV electronics and external sensors

• Rated for up to 1.5A continuous current load

• Provides a cost-effective hardware repair solution for flight controllers with failed onboard 3.3V regulators

• Ultra-compact footprint designed to be easily shrink-wrapped and tucked into tight FPV frames
