LM393 Dual Comparator Module

Overview

The dual-channel comparator module
uses
a potentiometer with a 2V input, a +INX input of 3.3V, and a 5V high output.

Important notes:

The input voltage for comparison must not exceed the supply voltage -1.5V.
If the supply voltage is higher than 5V, replace the LED current-limiting resistor accordingly.
The LM393 supports 3~36V supply, but this design uses 5V as the standard; please note this.
Power input is prohibited via coaxial cable.
