Logic Level Shifter is needed if you need to connect a 3.3V device to a 5V system. This 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.
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 and the device to the ‘GND’ pin.
- 4 channels of logic and high voltage low voltage logic two-way transformation
- Small module, 1.5cm X 1.3cm
- Can be used directly by putting it on a breadboard
