DESCRIPTION The 2 Channel Logic Level Converter is a small device that safely steps down 5V signals to 3.3V and steps up 3.3V to 5V. FEATURES Bi-Directional Translation: Translates signals both ways (up and down) without requiring direction-control pins. Voltage Compatibility: Steps down 5V signals to 3.3V and steps up 3.3V to 5V. It is also widely compatible with 1.8V and 2.8V devices. Channel Capacity: Features two independent, high-speed channels suitable for protocols like I2C (SDA/SCL) and UART (TX/RX). Breadboard-Friendly: Compact in size and designed with standard pin spacing for direct mounting onto a breadboard.Simple Wiring: Requires both the high-voltage 5V and low-voltage 3.3V sources to be connected to the board, alongside a common ground. Dimensions 15 x 15 x 2mm Weight 2g APPLICATION TTL Logic Level Converter Bidirectional Logic Level Conversion I2C Sensor Integration: Level shifts the Serial Data (SDA) and Serial Clock (SCL) lines. This allows you to connect 5V systems (like a classic Arduino Uno) to low-voltage sensors (like modern temperature or IMU chips). UART Serial Communication: Converts Transmit (TX) and Receive (RX) lines so a 3.3V device (e.g., a Raspberry Pi) or wireless module (e.g., ESP8266/ESP32) can communicate with a 5V MCU without frying its pins. Legacy Component Upgrades: Lets you integrate new 3.3V shields and expansion boards into older 5V mainboards, or vice versa, over standard two-wire digital buses. General Purpose 2-Wire Digital Bus: Handles various 2-wire bidirectional communication buses like 1-Wire, ensuring voltage domains remain isolated.
