AXL 400A Power Distribution Board, 14-60V, 8 ESC Outputs, Dual BEC

The AXL 400A is a power distribution board for heavy-lift multirotors and other high-current UAV platforms running batteries up to 14S. It takes a 14–60 V input, splits it across eight ESC outputs and adds Hall-effect current sensing, soft power switching and two regulated BEC rails, covering what would otherwise need a separate PDB, current sensor and pair of BECs.

Key features

• 4-layer PCB with large 2 oz copper planes carries up to 400 A of continuous distributed load while keeping resistive losses and voltage drop down.
• Eight solder-pad ESC outputs, each rated up to 60 A, for quad, hex and octocopter layouts.
• Hall-effect current sensor for real-time power monitoring.
• MOSFET-based soft power switching for controlled power-up and shut-down, with a JST port for an external power switch.
• Regulated 5 V 4 A and 12 V 4 A BEC outputs for auxiliary electronics, plus a dedicated JST flight-controller power output and an LED power indicator.

The 60 A per-output limit is the figure to check: confirm each motor and ESC's peak current stays under it, and size the main battery leads for the combined draw of all motors.
