Description
This module is a two-stage operational amplifier based on the LM358 chip. It is designed to amplify weak signals, including DC voltage signals and pulse signals, providing high precision for signal processing.
The module features two potentiometers that allow independent adjustment of the gain for each stage. Since the total gain is the product of the first and second stage gains, the device can achieve significantly high overall amplification.
With its compact size and stable performance under single-power supply, this module is ideal for measurement circuits, sensors, and various electronic projects requiring pre-amplification of low-voltage signals.

Норм штука, справилась с усилением слабого DC сигнала. Немного пришлось повозиться с калибровкой, но в целом все ок.

Отличный модуль для моих датчиков. Настроил усиление через подстроечники, работает стабильно, сигнал чистый. За свои деньги вообще топ.
