THE NEXT GENERATION ARDUINO NANO

While we certainly do love the Arduino Nano for its low-cost and versatility in projects, it’s unarguable that every tools has its gripes. For one maker in particular, there were enough complaints to merit a redesign of the entire board. While Arduino may or may not be interested in incorporating these changes into a redesign of the development board, there is certainly room for a new manufacturer ...

A data-acquisition system on a chip

Multifunction data-acquisition systems have been around for a long time as stand-alone instruments, plug-in cards, cabled computer peripherals, and embedded in systems. Such systems are often designed with separate ADCs, DACs, and digital I/O devices. Many microcontrollers include ADCs and DACs, but that locks you into using that device. The AD5592R from Analog Devices combines all of these I/O functions, l ...

PCB layout design with DipTrace – An overview

DipTrace is a sophisticated schematic and PCB layout software. I had it installed on my computer for over a year but have never really used it. Since I needed a super simple PCB for some 78XX / 79XX type linear regulators, I decided to use this opportunity for my first steps with DipTrace. DipTrace offers different prices for different packages [1]. The cheapest version, DipTrace Starter (300 pins, 2 signal ...

App note: Lithium ion battery charger using C8051F300

Introduction Driven by the need for untethered mobility and ease of use, many systems rely on rechargable bat- teries as their primary power source. The battery charging circuitry for th ese systems is typically implemented using a fixed- function IC to control the charging current/voltage profile. The C8051F30x family provides a flexible alterna- tive to fixed-function batt ery chargers. This appli- cation ...

Arduino Nano to Arduino Uno Adapter

Arduino Nano is a nice, small and cheap member of the Arduino family. It is based on the Atmega328 chip, what makes it as powerful as the biggest his brother Arduino Uno, but it can be obtained for less money. In Ebay now Chinese versions can be bought for less than 3 USD. Additionally to its smaller size comparing with Arduino Uno, the Nano board has also the advantage to have two more analog inputs A6,A7. ...

Power and Dependent Sources

Determine the power absorbed by the VCVS in the figure. Solution: The VCVS consists of an open circuit and a controlled-voltage source. There is no current in the open circuit, so no power is absorbed by the open circuit. The voltage vc across the open circuit is the controlling signal of the VCVS. The voltage Vc (across 2 ohm resisitor) measures vc to be vc = 2V. The voltage of the controlled voltage sourc ...

USB TO 12V BOOST CONVERTER

This project provides 12V output from any USB power source, like PC USB port, USB adapter or power banks. LM2577ADJ boost converter IC is the heart of the project. The IC can handle load up to 800mA, it’s advisable to use only 200mA load on output to be on the safe side. The LM2577 are monolithic integrated circuits that provide all of the power and control functions for step-up (boost), fly back, and forwa ...
