compact dual-output bec power module for fpv drones — 5v/2a or 12v/3a switchable

the iflight blitz psm bxn 5d2ud6 is a miniature switching step-down bec (battery eliminator circuit) power module designed for fpv drones and rc aircraft. using high-efficiency synchronous rectification technology, it steps down input voltages from 6v to 35v to a stable, regulated output — making it compatible with 2s through 8s lipo batteries. the output voltage is user-selectable between 5v/2a and 12v/3a via a simple short interface, providing flexible power delivery for flight controllers, cameras, vtx units, and other onboard electronics. at just 1.7g and 12×14×4.5mm, it integrates cleanly into any fpv build without adding meaningful weight.

key features

• dual output voltage – 5v/2a or 12v/3a selectable via short interface
• wide input range – 6-35v (compatible with 2s-8s lipo)
• switching step-down – high-efficiency synchronous rectification
• ultra-compact – 12×14×4.5mm footprint
• lightweight – only 1.7g
• simple voltage selection – short interface for 12v, open for 5v
• stable regulated output – clean power for sensitive electronics

perfect for
