Arduino Compatible Logic Level Converter Module Special Category for ULED-AT-2 then filters and amplifies theArduino Compatible While most of the modules used in the Arduino world are 5V logic, some are 3. 3V. And unfortunately, connecting them directly often results in "letting out the smoke"! This little module is the answer. Provides two bi directional channels to safely marry 3. 3V with 5. 0V. Drops straight into solder less breadboard or can be soldered into your own PCBs. Two bi directional channels 12 pin DIL package Specifications Width : 35. 0mm
