Logic Level Converter 3.3V 5V TTL

The Logic Level Converter 3.3V 5V is a small bi-directional level shifter that lets 3.3 V and 5 V devices talk to each other safely. Use it when a 5 V sensor, display or Arduino needs to exchange digital signals with a 3.3 V board such as an ESP32, ESP8266 or Raspberry Pi, whose pins can be damaged by 5 V.

Logic Level Converter 3.3V 5V Specifications

• Low-voltage side: 3.3 V
• High-voltage side: 5 V
• Direction: bi-directional
• Signal type: digital logic signals
• Power: separate reference supply pins for each side, plus ground
• Pin pitch: 2.54 mm headers, fits breadboards

Logic Level Converter 3.3V 5V Applications

• Connecting 5 V modules to ESP32, ESP8266 and Raspberry Pi GPIO
• Serial (UART) links between 3.3 V and 5 V boards
• Driving 5 V logic inputs from 3.3 V microcontrollers
• Mixed-voltage prototypes on a breadboard

What's in the Box

• 1 × logic level converter module

Tip: Power both sides: connect the low-voltage reference to 3.3 V, the high-voltage reference to 5 V and join the grounds. The module shifts signals only; it cannot supply power or convert analog voltages.
