voltage DCDC regulator PCB designed for reliable power conversion from 2 to 12S LiPo battery packs. Jumperselectable output voltage and current capacity make it suitable for demanding RC, FPV, and DIY electronics projects. Key benefits Wide input range: accepts 2 to 12S LiPo, eliminating the need for multiple converters when working with different battery configurations. Jumperselectable outputs: choose 5V, 5.5V, 6V, 7V, or 9V quickly to match cameras, flight controllers, video transmitters, servos, or other peripherals. current handling: designed to support up to 20A, enabling stable power delivery to mid to power components. Compact footprint: PCB size 45 mm x 26 mm x 8 mm fits into tight builds and simplifies integration into frames and enclosures. Improved conversion efficiency: optimized for efficient voltage conversion to reduce losses and maintain stable output under load. Function and compatibility Converts voltage LiPo battery input to a steady, selectable lower voltage for downstream electronics. Compatible with common RC, FPV, robotics, and portable electronics that require 5 to 9 volts and current. Jumper selection allows fast reconfiguration without soldering, useful for testing or multiconfiguration builds. Performance and installation notes Rated for up to 20A; ensure wiring, connectors, and solder joints are sized appropriately for the intended current. Compact PCB simplifies mounting in constrained spaces; allow some airflow when operating at current to aid heat dissipation. Follow standard safety practices when working with LiPo batteries and current connections. Typical applications Multirotor and FPV systems: power flight controllers, video transmitters, onboard cameras, and analog or digital accessories from a single LiPo pack. Robotics and RC vehicles: supply servos, motor controllers, sensors, and control electronics where stable regulated voltage is required. Portable electronics and lighting: run LED arrays, chargers for peripherals, or custom handheld devices from 2S to 12S LiPo battery inputs. Specifications summary Input: 2 to 12S LiPo battery packs Output voltages (jumper selectable): 5V, 5.5V, 6V, 7V, 9V Maximum current: up to 20A PCB size: 45 mm x 26 mm x 8 mm This regulator PCB provides a compact, flexible, and current solution for converting LiPo battery voltage to common system voltages, helping streamline power management in a wide range of projects.
