Single Channel Comparator Module LM393 Voltage Detector Board, Adjustable Reference Trimmer, 4.5 to 28 Input for Threshold Projects

Reference Voltage Control: The onboard trimmer lets you set the reference voltage directly on the board, helping you adjust switching behavior for prototype work without adding extra control hardware Single Module Package: You receive 1 assembled comparator module with an LM393 chip layout, keeping quantity expectations clear for replacement use, circuit experiments, or focused project planning Compact Board Footprint: The 39.5 x 17 mm size helps this comparator board fit tighter layouts, breadboard stations, and electronics project builds where control hardware must stay space efficient Comparator Output Response: This LM393 voltage comparator module compares an incoming input with a set reference point, then delivers high or low output for threshold detection in compact circuits Wide Input Window: Built for 4.5V to 28V input conditions, the module supports flexible low-voltage project planning while keeping the board format practical for prototyping and circuit integration
