Castellated holes are used to mount one PCB onto the surface of another PCB or to create custom edge-connection structures on a circuit board. They can be designed in different forms depending on the application. In many cases, they appear as half-plated holes along the edge of the PCB. However, depending on the manufacturing method and design requirement, they may also look like a smaller or larger section of a cut circular hole. This structure can help with alignment duri

Capacitor Selection Overview Capacitors are used in almost every area of electronics. Although their basic operating principle is the same, they can perform many different functions depending on the circuit structure, signal type, frequency range, voltage level, and energy requirement. For this reason, capacitor selection is an important part of electronic circuit design. Selecting the correct capacitor type requires understanding both the electrical requirements of the app

DRV-RGB-12V5A RGB LED Driver DRV-RGB-12V5A has been introduced as an RGB LED driver board for 12 V RGB LED strip applications. The module operates from a 12 V supply and supports up to 5 A current through the terminal block input. It provides separate red, green and blue LED outputs, allowing each color channel of an RGB LED strip to be controlled independently. Independent RGB Signal Inputs The DRV-RGB-12V5A board includes three color signal inputs: RI, GI and BI. Thes

CTS-RGB Sound Visualizer Module CTS-RGB has been introduced as a sound visualizer module for RGB lighting applications. The module detects ambient sound, converts it into electrical signals and analyzes these signals to generate RGB color control outputs. This allows RGB lighting behavior to respond dynamically to speech, music or environmental sound. Sound-Based RGB Control CTS-RGB is designed to create color transitions based on sound characteristics. The module evalu
