What is a Transformerless Power Supply? A transformerless power supply is an electronic circuit that converts the high voltage alternating current (AC) from the mains supply to a low voltage direct current (DC) suitable for powering electronic devices, without using a transformer. It is a cost-effective and compact alternative to […]

Introduction to PCB Grounding Proper grounding is essential for the reliable operation and performance of printed circuit boards (PCBs) and electronic circuits. PCB grounding refers to the techniques and strategies used to create a low-impedance path for electrical currents to return to their source, minimizing noise, electromagnetic interference (EMI), and […]

What is an IGBT? An IGBT is a three-terminal power semiconductor device that combines the high input impedance and fast switching characteristics of a Metal Oxide Semiconductor Field Effect Transistor (MOSFET) with the high current and low saturation voltage capability of a Bipolar Junction Transistor (BJT). This combination allows IGBTs […]

What is a Prototype and Why is it Important? A prototype is an early sample, model, or release of a product built to test a concept or process. It is a crucial step in the product development process, as it allows companies to evaluate the feasibility, performance, and potential of […]

Introduction to the DS1307 Real-Time Clock Module The DS1307 is a popular real-time clock (RTC) module that provides accurate timekeeping for embedded systems, including Arduino projects. This low-power chip maintains the current date and time, even when the main power supply is interrupted, thanks to its built-in backup battery. In […]

Introduction In the world of printed circuit board (PCB) manufacturing, two essential components play a crucial role in determining the quality and performance of the final product: prepreg and core. Both prepreg and core are used in the construction of multi-layer PCBs, but they serve different purposes and have distinct […]

Introduction to LM35 Temperature Sensor The LM35 is a precision integrated-circuit temperature sensor, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. It is a popular choice for measuring temperature in various applications due to its high accuracy, low self-heating, and easy interfacing with microcontrollers or other electronic […]

What is a PCB Trace? A printed circuit board (PCB) trace is a thin strip of copper or other conductive material that forms the interconnections between components on a PCB. Traces carry electrical signals and power between the various components soldered to the PCB. They are essentially the “wires” of […]

Understanding Lithium-Ion Battery Charging Charging Stages Lithium-ion batteries require a specific charging process to ensure safe and efficient operation. The charging process typically consists of three stages: Constant Current (CC) Stage: In this stage, the charger supplies a constant current to the battery, gradually increasing the battery voltage. The current […]

What is a Breadboard and Why is it Important? A breadboard is an essential tool for anyone working with electronic circuits. It is a rectangular plastic board with a grid of holes that allows you to quickly and easily prototype and test electronic circuits without the need for soldering. The […]
