Describe:Size: 2.7*1.1CMColor as shownInput voltage range: DC5.5~32VOutput voltage: 5V (+-0.1V)Continuous output current: 1APackage includes: 1Pc Voltage RegulatorThe DC-DC synchronous rectification step-down module has ultra-high conversion efficiency and low heat generation. Input DC5.5~32V, stable output 5V 1A long-term work, no need to add heat dissipation. The pins are compatible with the LM7805 three-terminal voltage regulator block and can be directly replaced. Ultra-small size, the same size as the TO-220 package, no need to test the space problem.
