SwiftWing PDB-14S – PDB with 12V and 5V Buck

The SwiftWing PDB-14S is a high-voltage power distribution board designed for heavy-lift drones and robotics platforms. It supports 8S to 14S LiPo battery systems with remarkable efficiency. Furthermore, this compact module combines high-current power routing with integrated buck regulators. You can eliminate bulky external BEC modules in most aircraft builds. Consequently, your setup experiences reduced wiring complexity and lower overall weight. Heavy-lift multirotors benefit from its reliable power delivery during demanding operations.

Key Features

• The SwiftWing PDB-14S supports input voltages from 29.6V to 58.8V nominal.

• It features onboard 5V and 12V buck regulators rated up to 3A continuous.

• Heavy-duty solder pads handle continuous high-current distribution up to 120A total.

• The 4-layer PCB with 2 oz copper guarantees low resistance and thermal stability.

• Integrated power rails supply clean energy to flight controllers and FPV systems.

• Dual mounting patterns support both 30.5mm and 40mm mounting hole configurations.

Integrated Power Regulation

This board provides clean power for onboard electronics. The 5V buck converter powers flight controllers, receivers, and sensors directly. Additionally, the 12V buck converter drives video transmitters and specialized payloads. Both regulators operate slightly above nominal voltages to maintain output stability under heavy loads. Moreover, the board features a dedicated footprint for an optional input capacitor. Adding a low-ESR capacitor improves system stability during aggressive throttle changes.

Applications

The SwiftWing PDB-14S excels in industrial UAV environments where high voltage improves motor efficiency. For example, commercial multirotors and long-endurance drones benefit from its high current capacity. In addition, high-cell-count robotics platforms rely on its robust dual-rail regulation. High-voltage power paths reduce current draw across your entire propulsion system. Therefore, your flight platform maintains lower operating temperatures during extended missions.
