Logic Level Converter

Created 31/08/2016 | Information for Logic level converter

The AB Electronics logic level converter is a small PCB which safely allows you to interface devices which steps down 5V signals to 3.3V signals and step up 3.3V signals to 5V.

The logic level converter has 4 inputs and outputs and can be used with I2C, SPI, UART, etc.

Introduction:

The board needs to be powered via two sources, 5V and 3.3V and your data lines are linked via pins 1 to 4 on each side so an input on pin 1 will be converted to the lower or higher output on the adjoining pin 1 this is repeated for pins 2 to 4.

The logic level converter is compatible with Arduino and Raspberry Pi

Dimensions: 15.6 x 13.7mm

The pins are 2.54mm spacing with 12.54mm between the two sides.
