Various types of devices that did not fit into any of the other converter subcategories. Most often these are integrated circuits or modules that are supposed to provide communication between two independent tools. Among others we have converters using such interfaces as I2C, SPI, HDMI, VGA, UART or USB adapters. In this category you will find over 50 useful converters that will come in handy for many projects - both electronic and robotic.

Other converters
Find all converters, which for various reasons could not be found in any other subcategory of this equipment. It is worth to browse through this offer as there are many devices that may turn out to be a perfect solution to your problems encountered when connecting independent elements. You'll find cable adapters that make it easier to access specific pins or simply set them in a different configuration to match a particular standard. We also offer accessories that work with small logic circuits to ensure that the signal received at the output is properly processed so that a second device can read it. Many products in the range are designed to work with tools popular among robotics and electronics engineers, such as Arduino, Raspberry Pi or popular displays.
What do we offer?
In the "other converters" category we offer, among other things, electronic component test kits. These allow for testing PNP and NPN bipolar transistors, diodes (and many other tools), and also have PWM and rectangular signal generators or frequency meters. Such devices usually have a screen on which the quantities relevant to the component are displayed. Among the simpler tools we have many types of adapters from HDMI to VGA, converters that allow the conversion of analogue audio and video signals to digital (inputs: PAL, NTSC, 2 x RCA chinch and USB A output), devices that convert digital audio to analogue, splitters for I2C or adapter from USB to female wires. We also have converters for connecting digital systems (e.g. microcontrollers) to high voltage systems, frequency generators (e.g. sine or rectangular signal), tools allowing the computer to communicate directly with sensors (UART, SPI, I2C, GPIO) or modules for connecting microcontrollers to CAN bus. We also offer voltage dividers, various drivers, optoisolators, boards with operational amplifiers, hubs and bridges for strain gauge beams, as well as FRAM memory or analogue signal isolator.
