This bidirectional logic level converter can be used with normal series, I2C, SPI and other digital signals. It does not work with an analog signal.
It is very easy to use. The card must be powered from the two voltages (high and low voltage) used by the system.
A high voltage (5 V for example) to the pin "HV", low voltage (3.3 V for example) in "LV", and the system ground to pin "GND". TTL Converter Module 5V - 3.3V Bidirectional 2 Channel I2C Logic Level features:
- 2 high voltage channels and low voltage logic logic for bidirectional translation
- 2 low voltage channels High voltage high voltage logic in unidirectional conversion
- The board module is compatible, it can be inserted directly in the use test panel
- HV to 5 V power

Connecting a 3.3V device to a 5V system is a challenge.
The bidirectional logic level converter is a small device that safely drops the signals from 5V to 3.3V and increases 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 it can successfully set its high and low voltages and go up and down between them safely on the same channel.
Each level converter has the ability to convert 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 sources of voltage (high voltage and low voltage) that your system is using.

Definition of the Hall effect: When a current passes through a bar of semiconductor (or conductive) material, and if an induction magnetic field B is applied perpendicularly to the direction of current flow, a voltage, called the Hall voltage, proportional to the magnetic field, and the current appears on the side faces of the bar.
This voltage is proportional to the speed of movement of the charge carriers, It is considerably higher in semiconductor materials than in metal conductors. Magnetic Sensor Characteristic: - Input Voltage: 3.8-30VDC - Output current: 40mA
High output current capacity -40 mA maximum absolute
Quad-Hall design virtually eliminates static mechanical effects
