Description
IIC I2C Logic Level Converter Bi-Directional Module 5V to 3.3V
This Level Converter- 2 Channel features two high-speed bi-directional 2 channels, allowing for safe and easy communication between devices operating at different logic levels.The logic level converter circuit converts signals as low as 1.8 V to as high as 5 V and vice versa, and its two channels are enough to support most common bidirectional and unidirectional digital interfaces, including I²C, SPI, and asynchronous TTL serial.
If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. A bi-directional Level Converter- 2 Channel 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 separates this Logic level converter from our previous versions is that you can successfully

Applications :
- Microcontroller Communication: Enables 5V microcontrollers (e.g., Arduino) to communicate with 3.3V devices (e.g., sensors) via I2C or SPI.
- Connecting Different Voltage Devices: Allows communication between devices operating at different voltage levels (5V to 3.3V).
- Interfacing with Sensors: Connects 3.3V sensors/modules to 5V logic devices like Arduino or Raspberry Pi.
- Level Shifting for I2C Bus: Shifts I2C signals between 5V and 3.3V for cross-voltage communication.
- Safe Communication Between Devices: Protects 3.3V devices by stepping down 5V signals to safe levels.

Customer Reviews
I needed a 5v to 3.3v level converter for I2C and UART communication.This product worked as expected in both directions.There is a silkscreen on the back with the pinout on it.
Does the job.
Work as expected, connected Data From NODEMCU to The device and the Output to LED Strip and worked OK.
Very nice bi-directional Logic Level Converters. All worked as advertised.
I use these all the time, need to order some more
I prefer the pinout of these to other models. Nice price. Works great for low speed IO applications.
Nice little 4-channel level shifting boards. Silk screen on back indicates all connections. Simple.
I don't know what thickness and sheerness have to do with level shifting, but that's me. I bought these to drive LEDs from a 3.3 volt micro GPIO and they work very well. The LEDs are driven from 5 volts, so their 3.1 volt threshold @25 ma. is handled.
Use with RPI to shift 3.3 to 5V to run data line of ws2812b LEDs. Works great.
Works as they are supposed to
