4-Channel Bi-Directional Logic Level Converter 3.3V to 5V (BOB-12009)

Reliable Voltage Level Translation for Everyday Electronics

Easily connect 3.3V and 5V devices with this 4-channel logic level converter, designed to safely bridge the gap between different voltage systems. Whether you’re working with Arduino, Raspberry Pi, or other development boards, this bi-directional logic level shifter makes mixed-voltage projects effortless and risk-free.

What is a Logic Level Converter?

A logic level converter (also called a voltage level translator) is an essential tool for anyone combining 3.3V and 5V parts. It protects sensors, microcontrollers, modules, and ICs from potential damage caused by direct high-voltage connections. With this 4-channel bi-directional logic level converter, you can send signals both waysup from 3.3V to 5V, and down from 5V to 3.3V.
