An interface is a contact or connector, a device that allows you to connect two elements together. Without the interface such connections could not function and thus it would be impossible to expand many electronic devices and advanced systems. An interface is also called a set of displays and manipulators, which include various types of buttons and knobs. It is through them that the device/chip communicates with the user and vice versa. Thus, the interfaces are in different forms and thus versatile and widely used. The offer of Botland includes all elements necessary to build electronic interfaces. Among them are level translators, digital line expanders and communication systems. All solutions offered by us are characterized by efficiency and reliability of work. They have a long life and are adapted to work under a heavy load, which is characterized today by many technologically advanced systems. So check our offer by comparing individual interface models.

Digital transmission with different voltages
The offer includes voltage level translators. For all digital transmission standards we deal with different voltage levels. They are assigned two digital states, namely low and high. The voltage around the power supply voltage, which is higher, is called the high state voltage. The low state voltage refers to the voltage located around the ground potential. There are situations when low and high state are coded by the difference of voltages. So it is different than in case of direct voltage coding. The voltage level translator is used in the cell where different standards of digital data transmission are connected together. They take the form of integrated circuits.
Communication interface controllers
In order to connect different communication interfaces with each other, choose one of our proposed communication interface converters, which are available in Botland store in different variants. Among many proposals you will find popular controllers of communication interfaces Wi-Fi and Ethernet. This is one of the most popular solutions and the most frequently chosen options. They allow you to connect, among others, to a computer or microcomputer using a serial interface (examples are I2C and SPI). The minicomputer system is not equipped with Internet access as standard. However, using a communication interface converter we can connect it via Ethernet or Wi-Fi cable.
For systems without digital lines
Layout designs differ in their functionality and the elements they contain. It may happen that there are no digital lines in them. Among them there are lines, which are responsible for controlling a large number of LEDs. In many cases it is necessary to use a large number of buttons, without which the circuit would not be functional enough. To make this possible, digital interface expanders are used. These are elements that have a digital serial interface on one side, while on the other side there is usually an 8- or 16-bit parallel interface. The use of expanders is therefore of great importance for expanding systems and supplementing them with new functionalities for digital lines.
