SwiftWing PDB-14S – 8S–14S High Voltage Power Distribution Board with 5V & 12V Regulators
The SwiftWing PDB-14S is a high-voltage power distribution board designed for 8S–14S LiPo systems, built for heavy-lift UAVs, industrial drones, and high-power robotics platforms.
It combines high-current power distribution with integrated 5V and 12V buck regulators, reducing wiring complexity and eliminating the need for external BEC modules in most setups.
Built on a 4-layer PCB with 2 oz copper, the board features enlarged high-current pads for improved current handling, lower resistance, and better thermal performance in demanding applications.

Key Features
- Supports 8S–14S LiPo input (29.6V – 58.8V nominal)
- Integrated 5V / 3A and 12V / 3A buck regulators (tested up to 5A)
- High-current ESC distribution with enlarged solder pads
- 4-layer PCB with 2 oz copper for low impedance power paths
- Stable regulated outputs for flight controller, GPS, VTX and payload systems
- Footprint for external input capacitor (recommended for high-current setups)
- Supports direct soldering for reliable high-current connections
- Dual mounting compatibility: 30.5mm and 40mm patterns
Designed for High-Voltage Systems
The PDB-14S is optimized for systems where higher voltage reduces current and improves overall efficiency. It is ideal for:
- Heavy-lift multirotor UAVs
- Industrial and long-endurance drones
- High-voltage propulsion systems
- Robotics platforms with high-cell-count batteries
Integrated Power Regulation
The onboard buck converters provide:
- 5V output for flight controllers, receivers, and sensors
- 12V output for FPV systems, VTX, and payload electronics
Outputs are regulated slightly above nominal values to maintain stable voltage under load.
