LLC I2C Click can be utilized as the level converter for logic signals, which makes it a very useful Click board™. The topology of this logic level conversion (LLC) circuit is perfectly suited for the bi-directional I2C communication. Although there are some specialized integrated circuits on the market, sometimes it is more convenient to have a simple solution made of just a few passive elements and four MOSFETs. Besides this, MOSFETs can withstand up to 20V across their terminals (12V VGS),...

There are a couple must-have boards that every engineer and hobbyist should have on their desk, and this PCA9306 dual, bidirectional voltage-level translator breakout is one of them! Because different parts sometimes use different voltage levels to communicate, voltage level translators can be the key to making different parts play nice. The PCA9306 is a dual bidirectional I2C-bus and SMBus voltage-level translator that's operational on the low side from 1.2V to 3.3V and on the high side from...

If you've ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The SparkFun 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. This level converter also works 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...

This is a board designed for opto-isolation. This board is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or noisy system. This board electrically isolates a controller from the high-power system by use of an opto-isolator IC. This IC has two LEDs and two photodiodes built-in. This allows the low-voltage side to control a high voltage side. We often use this board to allow a microcontroller control servos or other motors that use a higher voltage than the...
