Pinout

Pin Description
HV High Voltage Reference (e.g., 5V)
LV Low Voltage Reference (e.g., 3.3V)
GND Common Ground
HV1–HV4 High Voltage Signal Channels
LV1–LV4 Low Voltage Signal Channels

Working Principle

The module automatically detects the direction of data flow and shifts voltage levels between the low-voltage and high-voltage sides using internal MOSFET-based circuitry. This allows safe communication between 3.3V and 5V systems without risking damage to sensitive components.

Typical Applications

  • Connecting 3.3V ESP8266/ESP32 to 5V Arduino
  • I²C sensor interfacing
  • SPI device communication
  • TTL serial communication between mixed-voltage systems
  • General digital signal level shifting
