## Description

Quickly converts 3.3V to 5V logic signals for Arduino and other development boards, with 4 channels and optical isolation for protection. It operates with 5V power supply on VCC and GND, uses PNP common cathode connection, and at 3.3V input it gets 5V output, switching up to 10 kHz. Simple connection via screw terminals.
Logic level converter module, from 3.3VDC to 5VDC, with optoisolator, compatible with Arduino and other development boards, with common cathode, PNP.
It has 4 channels and is used when you want to convert a logical signal from 3.3V to 5VDC.
It requires a power supply for the output voltage, in the case of this module, of 5VDC connected to the VCC and GND pins (they are easily recognized because they have the Blue connector.
For each separate input, the Plus and Minus of the 3.3V signal will be connected, and on the output there will be only the output pin of the signal modified to 5V.
A High Level signal of 3.3V on the input corresponds to a signal of 5V on the output. A Low Level signal of 0V on the input corresponds to a signal of 0V on the output.
