Rules and guidelines for drawing good schematics

There are a lot of poorly drawn schematics here. A few times people have actually asked for critiques of their schematics. This question is intended as a single repository on schematic drawing rules and guidelines can point people to. The question…

Why was Mini USB deprecated in favor of Micro USB?

Mini USB connectors were standardized as part of USB 2.0 in 2000. In 2007, the USB Implemeters Forum standardized Micro USB connectors, deprecating Mini USB connectors four months later. Why? What are the advantages of Micro USB over Mini USB that…

Standard nomenclature for component types

What prefixes should be used on reference designators for components of various types? I think we can all agree that "R##" refers to a resistor, "C##" refers to a capacitor, and "L##" refers to an inductor. Beyond that, it appears to be a mishmash…

"Standard" components...?

In class we are designing a few different circuits and it uses some diodes and opamps. Everything is fine on paper and everything makes sense. These are only ever refereed to as a "diode" or "opamp". So then I made a simulation on pspice. However…

What is a digital video port?

I see a few questions here casually mention that image sensor modules have a "standard parallel digital video port (DVP) or ... MIPI high-speed serial interface" "Where do I start with embedded video?" "Processor with hardware camera interface…

Official GPS protocol documentation?

Searching for "GPS protocol" reveals many sources for processed GPS data, e.g. NMEA or binary outputs of GPS units. Where is the official documentation for the GPS satellite - receiver protocol? Or any interesting supplemental material that might…

Standard Volt and Ampere

A recent question on here asking about how to calculate the accuracy of a circuit got me thinking about calibration in general. In particular, as EEs we routinely use volts and amperes as a unit and yet these are both rather vague and hard things to…

How do you pronounce the following set of 'words'?

I've heard people pronouncing the following 'words' in different ways and I would like to know the correct way of pronouncing them. SPI (spy vs s.p.i) I2C (I.2.C vs I.squared.c) LED (lead vs L.E.D) I use s.p.i, i.2.c and l.e.d because these are…

‘One for all’ standardized land pattern v.s. specified land pattern in datasheet

I’ve designed lot of ‘simple’ PCBs for hobby and proof-of-concept purposes, but never for (mass)manufacturing. In order to do so in the future, and further expanding my design skills and knowledge, I’m exploring the different package outline…

What is *actually* a *standard part*?

This is something that has bothered me for ages. I wasn't sure it could be made up as a question here, until Olin Lathrop suggested it to me in a comment to another thread. We all know what we are talking about when someone mentions, for example, an…

How to read Scaled Graphs?

Please ignore the graphed lines, those are irrelevant to the question, it's the graph itself that's relevant. I see this type of graph used all the time, between multiple manufacturers and device types. It's a plotted graph, x * y, where x could be…

What standard governs the dimensions of SMT chip resistors and capacitors?

I am aware of the JEDEC registered outlines, which define the standard mechanical dimensions and tolerances for a wide variety of solid-state packages. However, these standards do not appear to cover two-terminal SMT resistors and capacitors (e.g.…

North American standard symbol for ferrite bead?

Many of the schematics I've seen in reference schematics use an the symbol of an inductor as the symbol for a ferrite bead (makes sense). But I've also seen other variants of it as well. I don't have the IEEE 315 document, but I know that there are…

What tools or standards can be used to improve embedded C code reliability?

I typically program PICs in C, usually for switched-mode converters. I've heard of various static analysis tools and standards like MISRA C that can be used to help improve the reliability of code. I'd like to know more. What standards or tools…
