Logic Converters

Many electronic devices use a logic voltage of 3.3V. Some boards, such as the Arduino UNO, are not suitable for these voltages, so it is necessary to use a converter that will make it possible to switch from one voltage to another. There are two types of logic converters: uni-directional and bidirectional. Uni-directional converters have all inputs associated with one voltage, and outputs with the other. Bi-directional converters have both inputs and outputs at each voltage value. Bi-directional converters can also be automatic and interchange output ports with input ports depending on the signal. Check our offer to find the most appropriate converters for your project and consult our forum or technical information to find out more about how they work.

TTL Converter Module 5V - 3.3V Bidirectional I2C Logic Level

Connecting a 3.3V device to a 5V system is a challenge.
The bidirectional logic level converter is a small device that safely drops the signals from 5V to 3.3V and increases 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 it can successfully set its high and low voltages and go up and down between them safely on the same channel.
Each level converter has the ability to convert 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 sources of voltage (high voltage and low voltage) that your system is using.

Level converters

Microcontrollers and peripherals often work on different logic levels - that is a 1 signal is indicated by a 3.3V in some circuits and by 5.0V in other. To make them "talk" to each other you need to bump up the signal or lower it down. And that is where level converters come into play. The easiest way to go about it is to get a bi-directional making it universal and easy to connect the circuit both ways - from higher to lower voltage and the other way around.

USB converters

Another "difficulty" in connecting and in general getting around with your new Arduino or any other controller might be connecting it to your PC or laptop. We are all well used to the USB ports and it is not surprising by all means. They are fast, they convenient. However, back in the day there plenty of standards used for communication and interestingly most of them are still used, even though maybe not in such popular uses. The two most used standards of transmission are RS232 and RS485 - often served by a popular 9 pin DB connector. However, for the development boards, what is the most probable is that you will be playing with straight 4 pin TTL connection. There is a range of controllers allowing for this conversion - starting with the class, quality and reliability of FT232 by FTDI through PL2303 through CH340. You name it we have it, in all price levels and from range of renowned and a bit less renowned producers!

ATmega programmers

Last but not least, you might not only need to connect your board to a laptop, but as well to program the ATmega on it. Well, you will need yet another equipment for that. ATmega programmers come in all kinds and with range of different functionalities. Revise our offering, and find an easy to use and effective microcontroller programer
