I2C 2 Channel 3.3V to 5V Bi Directional Logic Level Converter

I2C 2 Channel 3.3V to 5V Bi Directional Logic Level Converter 

The I2C 2-Channel Bi-Directional Logic Level Converter is a compact module designed to safely interface devices that operate at different logic voltage levels. It allows communication between 3.3V systems (like ESP8266/ESP32, Raspberry Pi) and 5V systems (like Arduino UNO, Mega).
It uses MOSFET-based level shifting, which supports true two-way data transfer, making it ideal for I2C, UART, 1-Wire, and general-purpose logic signal translation.
