20Pcs 8-Channel Logic Level Translator Converter Bi-Directional Module

20Pcs 8 Channel Logic Level Translator Converter Bi Directional ModuleIntroduction If youve ever tried to connect a 3 3V device to a 5V system you know what a challenge it can be The SparkFun bi directional logic level converter is a small device that safely steps down 5V signals to 3 3V AND steps up 3 3V to 5V at the same time This level converter also works with 2 8V and 1 8V devices What really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the same channel Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side The level converter is very easy to use The board needs to be powered from the two voltages sources high voltage and low voltage that your system is using High voltage 5V for example to the HV pin low voltage 3 3V for example to LV and ground from the system to the GND pin Feature 8 channel high voltage and low voltage logic bidirectional translationMini size 4 1cm x 1 8cmComes with 2 rows of 6pin unsolderedCompatible breadboard can be directly inserted in the breadboardNote For example High voltage 5V low voltage 3 3V HV connect 5V power supplyLV connect 3 3V power supplyGND connect negative two power supply commonsLVx input and output is 3 3V TTL HVx input and output is 5V TTL LVx and TVx bidirectional transfersPackage inc
