## Description

4-Channel Bi-Directional Logic Level Converter Easily connect devices operating at different voltage levels with this 4-Channel Bi-Directional Logic Level Converter. Designed for safe and reliable voltage translation, it allows 3.3V and 5V devices to communicate without risking damage to sensitive electronics. Featuring four BSS138 MOSFETs with onboard 10K pull-up resistors, this compact module supports bi-directional level shifting from as low as 1.8V on the low-voltage side up to 10V on the high-voltage side. While optimised for I2C communication, it also works perfectly with SPI, UART/TTL serial, and many other digital interfaces. Fully assembled and tested, the board provides four independent converter channels and includes two 6-pin header strips for easy integration into your projects. Features  Safely connects 3.3V devices to 5V and higher voltage systems   Bi-directional voltage translation for both input and output signals   Operates from 1.8V to 10V   Four independent level-shifting channels   Uses 4 × BSS138 MOSFETs with 10K pull-up resistors   Ideal for I2C, SPI, UART/TTL serial, and other digital interfaces   Fully assembled and tested PCB   Compact and easy to integrate into prototypes and finished projects  Package Includes  1 × 4-Channel Bi-Directional Logic Level Converter Module  A must-have module for Arduino, Raspberry Pi, ESP32, STM32, and other mixed-voltage electronics projects.
