Luckkyme 10PCS 4 Channels IIC I2C Logic Level Converter Bi-Directional Shifter Module 3.3V to 5V for Arduino
Description
- Logic level shifter Bi-Directional with 4 channels between high logic voltage and low logic voltage
- 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
- This 4 channels 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
- Small module size: 1.3cm X 1.5cm/0.51"x0.59"
- Compatible with breadboard, can be directly use in breadboard

ACTIVE LOW
These are active low and although probably work fine for IIC / I2C, they are not useful for voltage conversion, for example 5v PNP sensor to 3.3v ESP32 input (my application).When you put 5v on HV and 3.3v on LV pins, it distributes it 5v to HV1-4 and 3.3v to LV1-4.Then if you tie HV1 to GND, LV1 goes to 0volts and vice versa.They work but not if you're trying to convert active high signals, as I was.After inquiring with Luckkyme, they issued a full refund without question.Still would have been useful to include in the description.

Great lo
It's a great tiny board, 4 bidirectional signals between 3.3 and 5 volt chips. Great for i2c

Low quality design
Functions as expected, but the PCB design is low on quality. Holes barely have any copper to solder.
