10-Pack 4-Channel Bidirectional Logic Level Converters

Modules that let a 3.3 V board talk to 5 V parts without damaging either side. Each module handles four signals, and the pack gives you ten for several builds.

Bridge 3.3 V and 5 V logic

• ✅ Four channels each. One module shifts four signals at once, enough for SPI or a set of I/O lines.
• ✅ Works both ways. Signals pass in either direction, so it is safe on data lines and not only on outputs.
• ✅ Ten modules. Build several prototypes without desoldering a module from a finished board.
• ✅ Ready for a breadboard. Headers come with the module, so it plugs straight into a breadboard or a PCB without extra parts.
