LM358 Dual Operational Amplifier Module — Comparator & Signal Conditioning

LM358 Dual Operational Amplifier Module — Comparator & Signal Conditioning

The LM358 dual op-amp module provides two independent operational amplifier channels for signal conditioning, voltage comparison, and amplification in Arduino projects. The LM358 operates from a single 3V–32V supply — no dual supply needed — making it ideal for battery-powered and 5V Arduino applications. Includes an adjustable threshold potentiometer for comparator applications.
