A module with 8 PC817 optocouplers. Allows you to add galvanic separation in the form of opto-isolation between electrical circuits

A module that provides a regulated, galvanically isolated power supply. It allows easy changing of the output voltage from 5 V to 3.3 V using the voltage selection pin (VSEL). Galvanic isolation between input and output effectively prevents problems related to ground loops and ground currents, ensuring stability and protection of the system. Pololu 5384
