Bi-Directional Logic Level Converter (4 Channel)

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).

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 connnect 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″).

SPECIFICATIONS:
Convert 4 pins on the high side to 4 pins on the low side or vice versa
Power from two voltage sources (high and low); high voltage goes to the HV pin and low voltage to the LV pin
Pinout labeled on modules
I2C signal capable
Breadboard compatible
Dimensions (excluding pins): 15.2mm (0.6″) length x 12.7mm (0.5″) width x 2.5mm (0.1”) height
Weight: 1.2g
