This 4 channel bidirectional logic level shifter allows mixed voltage parts to be used in the same system.
Each bi-directional level shifter can convert signals from 1.5V to 18 V in both directions. The module provides a set of four channels that for voltage conversion. It can be used for a variety of four pin digital interfaces and is ideal for use with I2C, SPI and TTL serial.
Use this logic shifter when connecting a 5V microcontroller to a 3.3V component or the other way around.
This module comes with optional male header pins that require soldering.
