BrainFPV Radix Li 20×20 Wing Power Board

The BrainFPV Radix Li Wing Power Board is a dedicated power distribution module engineered specifically for small fixed-wing FPV aircraft. Designed to pair directly with the BrainFPV Radix Li flight controller, it handles primary power management, voltage regulation for control surfaces, and battery telemetry in a micro-sized footprint.

Key features

• Streamlines wiring between the battery, ESC, servos, and Radix Li flight controller.
• Integrated 5V BEC designed specifically to handle the inductive load and continuous current draw of fixed-wing servos.
• Built-in precision current sensor for real-time OSD power consumption tracking.
• Space-saving 20x20mm form factor fits tight wing bays and narrow fuselages.

Specifications

• Mounting pattern: 20x20mm
• Platform compatibility: Fixed-wing / FPV planes
• Ecosystem compatibility: BrainFPV Radix Li Flight Controller
• Regulator: 5V servo-optimised BEC

This power board is an ideal companion for sub-250g builds and compact foam wings where standard 30.5x30.5mm electronics are too large, eliminating the weight and wiring mess of external standalone BECs.
