Someone just created the tags 208VAC and 230VAC. If think we need to create a policy about tag usage related to supply voltages. Clearly, stating the supply voltage is highly relevant information ...
I have a 30MHz TCXO circuit (TCXO datasheet) like this serving as local oscillator to a RFIC: The RFIC manufacturer recommends to "add filtering caps" for high RF output cases. That is >20d...
I'm looking for input from anyone with insight in the PLC world. How do PLCs usually measure 4-20mA current loops? I would assume it's one of these two alternatives: Through an external "shunt"...
Using a P FET for polarity protection like this means that in case you flip + and -, the gate will be inactive, meaning that GND which is now connected to drain will get disconnected - no current w...
Pitch is defined as the center-to-center measurement between two pins/legs of the component. Connectors in particular are always categorized by manufacturers/retailers based on pitch, so it is the...
The term absolute maximum ratings has a well-defined meaning in datasheets, meaning stress values that the part will endure for a short period of time without breaking. And the opposite: if you exc...
The reason I left that comment is because determining the quality of a coaxial cable involves electrical engineering more so than an electrician, let alone some DIY. The rule of thumb "would you a...
Draft for a tag creation/deletion criteria A tag must fulfill all of the below requirements or it may get renamed or deleted: A tag must be named appropriately, considering Tag naming guideline...
Additions: Do not use company names in tags. Questions should be about specific products, not about companies. Furthermore, silicon companies merge/split and purchase each other all the time, ...
Breakpoints are beyond the scope of the C language, so this is up to the specific debugger and CPU core. What you will probably have to do to block accidental breakpoints is to not provide any debu...
A while back someone suggested that we added a section for reviews to the site - How about a new section for code reviews? From that meta thread we gathered that: There seems to be community con...
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 ...
The 45° routing makes it easier to route multiple parallel traces across the PCB - I would say that's the main reason why they are so popular. Whereas 90° turns of multiple parallel traces next to ...
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...
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'...
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...
Using voltage as a way of saying "I'm dealing with voltage here" is pointless - most electronics questions do. I think the voltage vs current tags are however relevant in the case when you need to...
I agree with everything said. I didn't really consider until now that Codidact (unlike Someplace Else) supports case-sensitive tagging. So in addition, perhaps add a note regarding the following: ...
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...
The main problem with a question along the lines of "how do you design a product for medical applications" is that it's way too broad. You cannot reasonably write a somewhat complete answer because...
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've done similar things on UART lines, but for significantly lower baudrates (9600 etc) than traditionally used on most CAN buses. It's also easier to do when you have 5V guaranteed to be well-ov...
