IIC I2C Logic Level Converter Bi-Directional Module 5V to 3.3V For Arduino
If you've ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be.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.

The purchase arrived late and out of time, I requested a refund, I was refunded, and a few days later the package arrived. I have notified Aliexpress, and they told me that it is the company's policy that, if the refund was due and the package arrived outside the expected time, I get to keep both things. Very professional. Now they just need someone to take action and change the carrier; the current one is "ecoscooting" with Correos España. These situations were almost non-existent before. By the way, the material arrived in good condition, as stated in the advertisement, and it works properly.

Received, all the parts for the invention I want to make have arrived. They look very good. I just need to make sure I don't solder incorrectly and that it works properly. I want to make a WiFi module for a pellet stove with several components.
