PCB

A printed circuit board (PCB) mechanically supports and electrically connects electronic components or electrical components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it. Printed circuit boards are used in all but the simplest electronic products. They are also used in some electrical products, such as passive switch boxes.

Current-Sense Amplifier with Dual Over Current Level Monitor & Alert Output

“The project presented here is a high common-mode current sense amplifier with two high-speed comparators to detect out-of-range current conditions. The comparators are configured to detect and respond to dual over current conditions. These devices feature an adjustable limit threshold …

Getting started with LoRa + AT commands

“MIDI controller-filter-router, sound generator, available in kit or fully assembled. Designed by pangrus’ electro acoustic lab in Italy. I got my hands on REYAX Lora modules, and in this tutorial, we will configure these modules to communicate with each other …

High-performance, High-reliability Bipolar Stepper Motor Driver

“The project presented here is a bipolar stepper motor driver. It is based on BD63731EFV chip which is a low-consumption driver that is driven by a PWM signal. The power supply voltage of the project is 8 to 28V DC …

Li-Ion/Li-Po 18650 Battery to 5V Boost Converter

“The project presented here is capable of supplying 400mA of current from a 3.7V Li-Ion/Li-Po Battery input with a 5V output. The converter has an internal soft start and internal frequency compensation features. The project is built using …

Modularized Narrowband FM Receiver

“MC3362 and ADF4351 based, modularized, NFM receiver. This receiver is designed to listen to the 2m band amateur radio conversations. This project is about MC3362and ADF4351based modularized, 2-meter narrow band FM receiver. In this design, the receiver splits into three …

Piezo Element Amplifier for Guitar and Violin

“The board presented here is a preamplifier for contact microphones that are used for amplifying the sound of musical instruments which do not contain electrical pickups, such as guitar and violins. Most contact microphones use a piezo element to convert …

Power-Saving PWM Solenoid Controller

“The project described here is a power-saving pulse-width modulator (PWM) controller for solenoids with an internal supply regulator. The board is based on the DRV110 IC which is a PWM current controller which is specifically designed for solenoid and relay …

BCD Watch (Binary to Decimal)

“What is BCD? The full form of BCD is binary coded decimal, as its name the binary digits is showing decimal value. It is a very simple representation of decimal numbers in different ways, so you can google BCD or …
