It combines the power of the ESP8266 Wi-Fi module with a user-friendly development environment based on the Lua programming language. NodeMCU has gained popularity among hobbyists, makers, and professionals due to its […]

What is PCB Impedance? PCB impedance refers to the opposition to the flow of electrical current in a printed circuit board (PCB). It is a critical factor in ensuring the integrity and reliability of high-speed digital signals and high-frequency analog signals in PCB designs. Controlling PCB impedance is essential for […]

What is a DC Chopper? A DC chopper is a power electronic device that converts fixed DC input voltage to a variable DC output voltage. It is essentially a high-speed switch that rapidly connects and disconnects the load from the power source, effectively “chopping” the DC voltage into discrete pulses. […]

Introduction to Opto-Isolator Circuits An opto-isolator, also known as an optocoupler or optical isolator, is an electronic component that provides electrical isolation between two circuits using light. It consists of an LED (light-emitting diode) and a photosensitive device, such as a phototransistor or photodiode, encased in a single package. The […]

Understanding DC Motor Speed Control To effectively control the speed of a DC motor, it is important to understand the fundamental principles behind its operation. A DC motor consists of a stator (stationary part) and a rotor (rotating part). When a DC voltage is applied to the motor, current flows […]

What are Halogen-free PCBs? Halogen-free PCBs are printed circuit boards that do not contain any halogenated flame retardants (HFRs) or other halogenated materials. Common halogens used in PCBs include chlorine (Cl) and bromine (Br). These substances can be harmful to the environment and human health when released during PCB manufacturing, […]
