  • Small converter that safely converts 5V signals to 3.3V and vice-versa
  • Works with 2.8V and 1.8V devices also
  • Successfully sets high-low voltages and step up-down safely on the same channel
  • RoHS compliant

The Logic Level Converter Bidirectional is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices. What really separates this Logic level converter from previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the same channel. The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the 'HV' pin, low voltage (3.3V for example) to 'LV', and ground from the system to the 'GND' pin.

4 Channels Logic Converter

Does what it says. Good product

compact and worthwhile

These work great to interface 3.3V controllers like the Teensy to 5V peripherals.

Perfect ESP32 to Arduino voltage level convertor

I'm using it for serial communication between Sparkfun ESP32 Thing and Botboarduino which only needs 2 channels, plus 2 spare which I'm using for digital lines. As usual Robot Shop provided prompt delivery and kept me updated of the delivery.

worked just fine

Hooked this up between a 5V function generator and an Arduino Due (3.3V). Worked like I expected.

It do is job

I used it with the Intel Edison breakout board to interface 1.8V IO with multiple 3.3 devices and it worked perfectly.
