Integrated voltage regulators: Many PDBs include built-in regulators (also called Battery Eliminator Circuits or BECs) that provide a stable, clean power supply at lower voltages (most commonly 5V or 12V) for sensitive components like your flight controller or FPV camera. Current rating: Ensure the PDB can handle the maximum current your drone's motors and ESCs will draw. As a safety precaution, it is best to choose a PDB with a current rating higher than your calculated needs. Form factor and layout: PDBs are available in various sizes and shapes. The most popular sizes for FPV drones are 20x20mm and 30.5x30.5mm. Look for one that fits your drone's frame and has convenient solder pad locations to keep wiring clean and short.
