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.


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.
