App note: PCB layout guidelines for high frequency signaling products

High speed board design app note from ON Semiconductor. Link here (PDF) There is an increase of devices and circuitry in usage of high speed, low consumption, small volume and lower interference. Hence PCB design is an important stage of electronic product design. It forms a connection between function and electronic components, and is also […]

Understanding Arduino UNO hardware design

Yahya Tawil over at All About Circuits has published an article on Arduino UNO’s electronic design and better understanding of its hardware: This article explains how Arduino works from an electronic design perspective. Most articles explain the software of Arduinos. However, understanding hardware design helps you to make the next step in the Arduino journey. […]

Reader questions: Thickness of PCB traces for a 120A solenoid

George asks how thick PCB traces should be for driving a 120A solenoid:  I’m doing a board design to power a solenoid that apparently draws 120 amps, but it’s only on for about 300 ms (I imagine it has some kind of “inverse curve” looking decrease with time, I haven’t thought about it too much). […]

App Note: Mixed signal circuit board layout considerations

Hli located an interesting app note from Cypress called “Mixed Signal Circuit Board Layout Considerations”. “It discusses how to layout a board to have good analog performance, even if you have digital stuff on the same board. Some parts are specific for the Cypress PSoCs, but much of the advice is applicable generally. The PSoCs […]
