D-Rc PDB400 8S 400A PDB Distribution Board for Drone Builds
A Compact Power Hub for 4S–8S Multirotors
The D-Rc PDB400 8S 400A PDB distribution board brings high-current power routing, voltage outputs, and flight data support into one compact platform. As a result, this drone power distribution board can help organize a four-ESC multirotor power system around a single central board. It supports 4S–8S LiPo batteries and has a stated 400A current rating. In addition, the board supports ESC telemetry and includes an onboard ammeter. Its 12V and 5V outputs can serve compatible flight-control and onboard electronics. The compact 56mm × 56mm footprint and 22.5g weight also suit builders who need to manage space and mass carefully. Meanwhile, the marked GND, VBAT, TLM, S1, S2, S3, and S4 connections provide a clear starting point for wiring. The product images show an octagonal black PCB with gold-colored contact pads, visible polarity markings, mounting holes, and exposed surface-mounted components. Therefore, it is designed as a practical connection point between a LiPo battery, four ESCs, and related flight-control equipment. Always verify electrical compatibility, polarity, solder quality, and installation requirements before applying power.

The specification image reinforces the board’s 4S–8S battery range, 400A rating, 12V and 5V outputs, telemetry support, onboard ammeter, 56mm × 56mm size, and 22.5g weight. It also identifies the seven primary connection labels used by the wiring layout.
Power Distribution for Four ESCs
The board is designed to route battery power toward four ESC connections in a multirotor setup. The VBAT and GND terminals provide the battery-side connection points. Meanwhile, S1 through S4 provide individual ESC signal connections, and TLM supports telemetry communication with compatible equipment.
The wiring diagram shows a 4S–8S LiPo input connected to the PDB400, with four ESC units arranged around the board. Consequently, the layout can give builders a more centralized approach to power and signal routing. However, the board does not remove the need for careful electrical planning. Confirm the requirements of the battery, ESCs, motors, flight controller, and connected accessories before assembly.
ESC Telemetry and Onboard Ammeter Support
The PDB400 supports ESC telemetry, which can allow compatible speed controllers to share system information with flight-control equipment. Therefore, builders may be able to monitor relevant data without adding a separate telemetry board. Compatibility still depends on the selected ESC and flight controller.
In addition, the onboard ammeter provides current-draw feedback for power-system monitoring. This information can support battery-use planning and post-flight review. Nevertheless, actual flight endurance depends on the motors, propellers, payload, battery condition, and flight style. Use the readings as part of a complete power-management process rather than as a guaranteed flight-time figure.
Compact Board Design and Dual Voltage Outputs
Space and weight matter in a multirotor frame. Fortunately, the 56mm × 56mm board size provides a compact installation footprint, while the 22.5g weight helps limit added mass. An additional marked dimension of 30.5mm also appears in the product imagery, so builders should compare the mounting and clearance information with their frame before installation.
Visually, the PDB400 uses an octagonal black printed circuit board with gold-colored perimeter contact areas and connector pads. Moreover, the board shows plus and minus polarity markings, mounting holes, central connector areas, and exposed surface-mounted components. The 12V and 5V outputs can support compatible onboard electronics, including flight-control and video-system components.
What the Package Includes
The product imagery identifies the following package contents. Accordingly, check the shipment against this list before beginning your build:
- One PDB400 distribution board
- Four M3 × 8 shock-absorbing balls
- One 130mm XT60 12AWG power cord
Is This Drone Power Distribution Board Right for Your Build?
Choose the D-Rc PDB400 when your multirotor project requires 4S–8S LiPo support, a stated 400A rating, four ESC signal connections, telemetry support, and 12V and 5V outputs. Its compact form can also help builders centralize power connections within a space-constrained frame. Before ordering, compare the board’s dimensions and connection layout with your electronics plan.
