Today, our desks are full of devices that require connection to be connected with the PC via USB, or we need to work with multiple devices that have USB ports. It became a problem as Laptops lack multiple ports, and this is where a USB hub or USB Port Extender comes in handy. This comprehensive guide demonstrates how to build a professional DIY USB hub with a power supply using…

Infineon introduced EZ-PD BCR (Barrel Connector Replacement) which is a highly integrated USB-C controller, together with the USB-C connector, it replaces barrel connectors, custom connectors, or legacy USB connectors in electronic devices. The EZ-PD BCR solution supports the USB Power Delivery (PD) standard that interoperates with all USB-C power adapters without the need…

Nexperia announced two PESD5V0R1BxSF extremely low clamping and capacitance bidirectional Electrostatic Discharge (ESD) protection diodes. Based on Treos technology with active silicon-controlled rectification, the devices ensure optimal signal integrity for USB4TM (up to 2 x 20 Gbps) data lines on laptops and peripherals, smartphones, and other portable electronic equipment…

STMicroelectronics facilitate the modernization of battery-powered products to capture the advantages of the latest USB Power Delivery (USB PD) technology, including faster charging and easy reuse of USB-C chargers. The new USB PD chargers can have a power rating up to 100W, by using the USB Programmable Power Supply (PPS) charging can be optimized by dynamically adjusting…

Most of the Analog Electronic circuits require dual power supply rails for proper balanced operation; this gets especially critical if we are designing Operational amplifier circuits. Negative supply voltage is also required in digital systems like A/D converters, op amps and comparators. In all these cases, the current requirement will be low, but generating such a -5V…

Before starting with Serial Communication Protocols, let’s break down the terminology into three parts. Communication is a very well-known terminology that involves the exchange of information between two or more mediums. In embedded systems, communication means the exchange of data between two microcontrollers in the form of bits. This exchange of data bits in a…

The features of digital products are growing enormously, which triggers the frequent usage of smartphones in several applications.  Thus, the battery backup time is decreasing. It will be fun to build a Power Bank for a Mobile Phone as a spare charging source for emergency purposes, which is also portable. In this article, we will discover how to make a power bank with…

In this DIY session we are building a web controlled surveillance robotic car using raspberry pi and a webcam. This could be a useful and inexpensive security and spy tool, which have many configurable options and can be built in few hours. In this IoT Project, we are mainly using Raspberry Pi, USB web camera and two DC motor with Robot chassis to build this Robotic car…

If you got fed up of buying new batteries for your circuits and want a reliable power source, then here is way. We use our Laptop or PC to charge you cellphones, similarly we can use power supply from our Computer’s USB for our circuits. Computer’s USB is a good power source for 5v DC regulated supply. Also when there is a circuit which consist motor like DC motor, Servo etc…
