SparkFun Bidirectional Logic Level Converter Board (16.1x13.3mm)
Convert 5V ↔ 3.3V signals safely with this 4-channel SparkFun logic level converter—ideal for Arduino, Raspberry Pi & more!
The SparkFun Bidirectional Logic Level Converter Board provides a reliable solution for interfacing devices operating at different voltage levels. It efficiently steps down 5V signals to 3.3V and steps up 3.3V signals back to 5V, ensuring seamless communication between mixed-voltage systems.
Designed for versatility, this converter board also supports 2.8V and 1.8V devices, making it a flexible tool for various electronics projects. Each converter features four channels, allowing for the bidirectional conversion of four pins on both high and low voltage sides—ideal for complex configurations requiring multiple signal conversions.
Features and Benefits
- Bi-directional conversion between 5V and 3.3V (and 2.8V/1.8V)
