4-Channel Logic Level Shifter - Pre-soldered Headers
Note: This logic level shifter breakout comes pre-soldered with headers.
If you have ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be! The 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. Each level converter can convert 4 pins on the high side to 4 pins on the low side, with power supply pins on each side.
The usage of the level converter is very straightforward. The board needs to be powered from the two voltage 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.
This module requires you to supply it with power from both the higher voltage level and the lower voltage level. Connect the higher voltage source to pin "HV" and its ground to pin "GND" near the "HV" pin. Also, connect the lower voltage source to pin "LV" and its ground to pin "GND" near the "LV" pin.
For example, if you were connecting your Arduino (5V signals) to an ESP8266 (3.3V signals), you would connect the "HV" pin on the module to the 5V supply pin on your Arduino and the "GND" pin near the "HV" pin to the "GND" pin on your Arduino. Then, you would connect the "LV" pin on the module to the 3.3V power source that is supplying power to the ESP8266 and connect the "GND" pin near the "LV" pin to the 3.3V power supply's ground. You would then connect the signal pin from your Arduino to one of the signal pins on this module (for example, pin "HV1"), and then you would connect the desired signal pin on the ESP8266 to the corresponding pin on this module ("LV1" if the higher voltage signal is connected to "HV1").
These are 4 Channel devices (works great for I2C or SPI) and will work with all microcontrollers, Arduino, Raspberry Pi, Intel Edison, etc. Use this module to connect two devices of different digital voltage levels. For example: connecting an Arduino (5V device) to an ESP8266 (3.3V device).
The logic level converter comes complete with header pins and can be used directly on a breadboard.
