To expand on Olin's answer about power dissipation, one theory is EX/ATEX qualification for explosive environments. This is likely needed for these kind of cars, given the massive energy in those b...
Quite often, I find myself knowing the technical term of an electronic component in my native language, but not the proper English term. For example when translating a manual or other technical doc...
Assume I'm a complete beginner at RF. Is there a way to measure return loss of an antenna, in such a manner that I can reliably reproduce the measurement later on? What I'm talking about is produ...
There's lots of specialized tools for various through-hole components overall, all of them generally called "lead benders". For TO-220 it appears that the term is lead bending/forming pliers. And t...
I'm not sure there's a technical reason, except usually the offered parts are multi-topology and then they could be listed as buck-boost while they at the same time could as well be used as flyback...
Step 1: Since 3V3_ISO would be LDO driven I would probably add a diode with the anode connected to the LDO output and a cathode connected with the LDO input to prevent the LDO to have output high...
It is some manner of BJT or MOSFET LED driver similar to for example this: NCR402T (just a random example, this one was PNP). They are literally called "SOT23 LED driver" (Mouser calls them "SOT23...
Regarding scope of embedded systems/firmware When we released Software Development, I made a push to make all forms of embedded systems programming off-topic and re-direct such to this site. The ...
I think they should have the same rep as ordinary posts. If they are high quality they will eventually accumulate a lot of up-votes over time. That's how the voting system is supposed to work, rewa...
Which are the parameters I should looking for when picking a flyback diode to be placed across a generic coil, such as a relay? That is: a coil with plain on/off functionality, for example a 24VDC ...
Check out What are the most common causes of CAN bus communication errors? As stated there, CAN requires a clock accuracy of 1.58% or your CAN node is non-compliant. I would recommend to use <1...
A little check list of some basic things to ask yourself before asking such a question: Is this some manner of high/mains voltage device? Repairing such electronics is very dangerous if you don'...
I just realized that the on-topic page https://electrical.codidact.com/help/topics doesn't address electronics assembly. This was always ok on "the old site", so I think it should definitely be ok ...
Baudrate is most often used to mean payload data bits/second. Simply picture a manchester encoded protocol, where each data bit corresponds to 2 physical bits in the raw data frame. If you have a b...
Our on-topic page currently lists homework questions as mostly off-topic, in the following manner: No interest in understanding or learning, "Just gimme da anser!" There has to be some element ...
The default scope in this EE community pretty much went with the same scope as the SE site. For now. These sites are new and most communities are still struggling to come up with what's off-topic ...
I'm curious about the market trend of certain kind of components (specifically, 0603 ceramic capacitors) and if I should start worrying about these getting phased out. I started to write a question...
You are forgetting that the transmitter plays part of it too. ACK is dominant simply because the transmitter sends ACK as recessive and any receiver must be able to override the recessive state of ...
The current applicable rule from https://electrical.codidact.com/help/topics would be: Off-topic ... High-level use of electrical devices. If your question treats a device like a black box and isn...
First of all, it depends on how much work the customer has done in advance. Do they have a proper spec? Do they at least have a bunch of key requirements? Or is it just "out there" and you must dra...
The key to writing good self-answered Q&A is to try to write the question just as if you didn't know the answer. That is, it has to fulfil the usual quality criteria for normal questions. This ...
Rasp PI is a PC in disguise - it is a single-board computer. As such it runs Linux and like any Linux PC, it doesn't allow real-time execution, direct access to physical addresses, deterministic ...
Are BOM/PCB assembly cost cost optimization questions on-topic here? I can see how chasing down specific parts, prices and vendors ought to be off-topic, so I don't mean outright shopping/second so...
I just made a post about using "company tags" over at Software Development: We know from SO that company name tags were always problematic since: Questions are about products, not companies. Gi...
