If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be.

This Bi-Directional Logic Level Converter is a small device that:

Safely steps down 5V signals to 3.3V

AND

Steps up 3.3V to 5V at the same time.

If you'd like to see a free demonstration of how you can get it working, view our Logic Level converter guide for a to-the-point account.

This level converter can also work with 2.8V and 1.8V devices. What really separates this Logic level converter from our 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. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side.

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.

Dimensions: 0.63 x 0.52" (16.05 x 13.33mm)

  • Arduino Audio Recorder with Playback
  • This project started with an idea, as most projects do. I wondered if I could use the Arduino UNO to record audio and play it back. I wanted something to amuse the grandkids. They would press a button, say something and the device would then repeat what they had said. ...
  • Rain Gauge Data Logger
  • Summary A Raspberry Pi 3B is used to collect digital counts from an electronic rain gauge (1mm of rain per reed switch closure by magnetic see-saw). It has been running without issues for over 12 months. A UPS powers the Pi so it is immune from short power glitches. The total count is displayed on an LCD screen with reset and inc/dec test buttons. “To HTML” and “To LCD” routines are also included to simp...
  • Television Media Centre
  • Introduction: I have a flat screen television that is about 7 years old that I purchased before Smart TVs were commonly available. What I wanted to achieve with My Pi project was to turn my slightly old TV into a media centre. I wanted to play music through my TV as well as play saved movies and stream internet content. It was important for me to be able to stream ABC iView and SBS On Demand as they provide a free service and ...
  • GraviTrack Enhancements - Lights and Sound
  • Introduction Searching for solar panels and related items on the Core Electronics website; I came across the Solarbotics GraviTrack Marble Machine Kit. I thought the kit would be a good educational tool for the grandkids. The kit was a hit, but the power switch was hard to access at the back of the machine and it only turned on and off. I had been experimenting with programmable RGB LEDs, Piezo speakers and a Light dependent re...
  • My ghostbusters proton pack
  • Hi all. Thought I'd share with you my modded Spirit Halloween proton pack. It's about 80% scale, which is plenty big enough for my 7-year-old son, and still looks decently sized on adults. As soon as I learned of this pack, 5-year-old me just had to get one. And I had just gotten my Arduino beginners kit a week earlier. I knew what had to be done :)...

    Works flawlessly with the Raspberry Pi to hook 5V components up to it's 3.3V GPIO pins. Easy to wire, extremely small, and plenty of channels to work with. Would definitely buy again. (Posted on 7/11/2018)

    I purchased this for a serial communications project requiring interoperability between 3.3V and 5V systems.

    This device not only handles data both ways (hence the bi-directional aspect) but thanks to the relatively low time delay of the BSS138 transistors on board, my 3MHz data transmissions were no problem.

    I would highly recommend this product! (Posted on 8/10/2018)

    great and cheap level shifter between 5V and 3.3V logic. You can connect without logic level shifting, but it will be running out of spec and will only work *most* of the time.. (Posted on 10/09/2018)

    I'm using this for translating between the Raspi (3v3) UART and the TTL interface of a RS-422 converter which is 5v only. Also for 3v3 <-> 5v conversion on a couple of 1-1wire busses. Seems to work well. Unfortunately it doesn't come with pins so you may want to buy some of those separately. (Posted on 30/03/2018)

    These work as expected... if only SBC makers would incorporate this into their board designs... would make life a whole lot easier! (Posted on 1/11/2017)

    Does what it says, it's tiny though which makes soldering a bit tricky. (Posted on 10/03/2016)
