What is a Relay Module? A relay module is an electrically operated switch that allows you to control a high-current circuit with a low-current signal. It consists of an electromagnet, a set of contacts, and a switching mechanism. When a small current is applied to the electromagnet, it generates a […]

Introduction to FR4 Laminate FR4 laminate is a widely used material in the manufacturing of printed circuit boards (PCBs). It is a composite material made from woven fiberglass cloth reinforced with an epoxy resin binder. The “FR” in FR4 stands for “Flame Retardant,” indicating its ability to self-extinguish and resist […]

What is a Data Bus? A data bus is a digital communication system that transfers data between components inside a computer or between different computers. It consists of a set of parallel wires or traces on a printed circuit board, each of which carries one bit of data at a […]

What is a PCB Via? A PCB (Printed Circuit Board) via is a small hole drilled through the board to allow electrical connections between different layers of the PCB. Vias are essential components in multi-layer PCBs, enabling the routing of signals and power between layers, which is crucial for complex […]
