Feature:1. The module uses a 6position DIP switch for coarse adjustment in 0.5V steps, which is convenient and quick to preset to any voltage of 1.5V33V.2. With indicator light display, and can display the voltage setting value, the operating status is clear at a glance.3. Onepiece molding without burrs, with light weight, can be operated with one hand, and installation is smoother.4. Both input and output use 4position binding posts, no need for multistrand wire connection.5. Made of highquality resin material, good flexibility and abrasion resistance, not easy to corrode after long time use.Specification:Item Type: Buck ModuleMaterial: ResinModel: LM2596S-ADJInput Voltage: DC5V-36VOutput Voltage: DC1.5V-33V (0.5V step), can be fine-tuned through adjustable resistanceOutput Current: Maximum 3A, rated 2ABoard Size: Approx. 58 x 35mm / 2.3 x 1.4in.Package List:1 x Buck ModuleNote:The trimmer potentiometer has been adjusted, the user can directly dial the DIP switch to set it in 0.5V steps. If the user adjusts the trimming resistor by himself, 0.5V step setting is required, just adjust the trimmer potentiometer back.
