LCD 2x8 display, PCB 58x30 mm, LED backlight, extended temperature range, "fast" 1-LED 20mA AMBER cyrillic

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
