Information for Logic level converter
The AB Electronics UK logic level converter is a small PCB that safely allows you to interface devices that step down 5V signals to 3.3V signals and 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.
