Build More with Logic Level Shifter, 4-Channel, Bidirectional

The Logic Level Shifter, 4-Channel, Bidirectional is a practical support part for wiring, level shifting, programming, or mounting in embedded builds.

It helps make integration easier and cleaner in prototypes as well as finished systems.

Why you'll love it

• Translates low ↔ high both ways: no direction pins needed for typical bus use—each channel is bidirectional
• Great for mixed-voltage systems: prevents 5V devices from misreading 3.3V highs and protects 3.3V devices from 5V logic
• Compact: tiny module with 0.1" pin spacing for breadboards and perfboards
• Protects low-voltage devices from higher-voltage logic
• Improves reliability when a “HIGH” level is borderline
• Clean solution for 1.8V/2.5V/3.3V ↔ 5V systems

What you can build

A useful add-on for prototype wiring, level shifting, board mounting, connector work, or programming tasks in embedded systems.
