IIC I2C Logic Level Converter Bi- Directional Module 5V to 3.3V For Arduino 4CH

The IIC I2C Logic Level Converter is a 4-channel bi-directional module that safely connects 5 V and 3.3 V devices. It lets a 5 V Arduino talk to 3.3 V sensors, displays and ESP modules over I2C, UART or SPI without damaging them, and every channel works in both directions, so no direction pin is needed.

IIC I2C Logic Level Converter Specifications

• Channels: 4, bi-directional
• Voltage levels: 5 V high side (HV) and 3.3 V low side (LV)
• Pins: HV, LV, 2 × GND, HV1–HV4 and LV1–LV4
• Design: MOSFET-based, with pull-up resistors on both sides
• Signals supported: I2C, UART serial, SPI and general digital signals

IIC I2C Logic Level Converter Applications

• Connecting 3.3 V I2C sensors to a 5 V Arduino Uno or Mega
• Serial links between an Arduino and ESP8266 or ESP32 boards
• Driving 3.3 V displays and SD card modules over SPI
• Interfacing Raspberry Pi GPIO with 5 V modules
• Mixed-voltage prototypes on the breadboard

What's in the Box

• 1 × 4-channel bi-directional logic level converter module

Tip: Connect HV to 5 V, LV to 3.3 V and both grounds together, then wire the 5 V signals to the HV pins and the 3.3 V signals to the matching LV pins. Both supply pins must be connected for the converter to work.
