3.3V to 5V TTL Level Shifter Converter Module – Bi-Directional Logic

This 3.3V to 5V TTL level shifter module allows safe and reliable communication between devices operating at different logic levels. It’s ideal for connecting 3.3V microcontrollers (like ESP32, ESP8266, and Raspberry Pi) to 5V devices (such as Arduino, sensors, and modules) without damaging components.

• Function: Bi-directional voltage level translation

• Supported logic levels: 1.8V–3.3V to 5V

• Channels: 4-channel conversion

• Compatibility: Works with I2C, SPI, UART, and general digital signals

• Applications: IoT devices, microcontroller interfacing, mixed-voltage circuits

• Compact design: Easy integration into breadboard and PCB projects
  Essential for safe and stable operation when working with mixed-voltage electronics.
