Shop Logic Level Converters by Type

Our logic level converter range may include products such as:

  • 3.3V to 5V Logic Level Converters: Modules used to connect 3.3V microcontrollers to 5V logic devices.
  • Bidirectional Logic Level Shifters: Converter boards that can translate signals in both directions for suitable communication lines.
  • I2C Logic Level Converters: Level shifter modules commonly used when connecting I2C sensors, displays or modules with different voltage levels.
  • Multi-Channel Level Shifter Boards: Logic converter modules with multiple signal channels for projects with several mixed-voltage connections.
  • Signal Level Converter Modules: Small interface boards used to adapt logic-level signals between compatible electronics devices.

Logic Level Shifters for Arduino, ESP32 & Raspberry Pi Projects

Logic level converters are commonly used when different boards or modules operate at different signal voltages. For example, many ESP32 and Raspberry Pi compatible boards use 3.3V logic, while some Arduino compatible boards and older modules may use 5V logic.

Using the wrong logic voltage can cause unreliable communication or damage sensitive inputs. Always check the voltage level of both devices, signal direction, communication type, speed requirements, pull-up resistors and pinout before connecting a level converter.

3.3V to 5V Logic Conversion for Mixed-Voltage Circuits

Logic level converter modules are often used with I2C, UART, SPI and simple digital signals, depending on the module design. Bidirectional converters are especially useful for I2C lines because data can travel in both directions between devices.

Frequently Asked Questions

What is a logic level converter used for?

A logic level converter is used to translate digital signals between different voltage levels, such as 3.3V and 5V logic.

Do I need a logic level converter for ESP32?

You may need one if connecting an ESP32, which usually uses 3.3V logic, to a 5V module or signal. Always check the connected device specifications before wiring.

Can I use a logic level converter with Raspberry Pi compatible boards?

Yes. Raspberry Pi compatible boards typically use 3.3V logic, so a level converter may be needed when connecting to 5V devices.

What is a bidirectional logic level shifter?

A bidirectional logic level shifter can translate signals in both directions between two voltage levels. These are commonly used for I2C communication and other suitable signal lines.

Can you help me choose the right logic level converter?

Yes. If you are unsure which converter suits your project, contact AuscomTech with your controller board, connected module, signal voltage levels, communication type and wiring details.
