Working Principle of Bi-Directional Logic Level Converter

The module works using MOSFET-based level shifting technology, which automatically adapts to the direction of data flow. Each channel can safely convert signals from low voltage to high voltage and from high voltage to low voltage without requiring external control signals.

When a device on one side pulls the signal low, the MOSFET allows the opposite side to follow, ensuring correct logic levels on both ends. This makes the converter ideal for two-way communication protocols like I2C.

Arduino, ESP, and Raspberry Pi Compatibility

The 4-channel logic level converter works seamlessly with:

• Arduino Uno, Nano, Mega

• ESP8266 and ESP32

• Raspberry Pi GPIO pins

• STM32 development boards

• Other 3.3V and 5V microcontrollers

It protects low-voltage devices from accidental exposure to higher voltages, increasing system reliability.
