  • What does strap mean in this context? - Electrical Engineering Stack . . .
    The violation you have, LUP 6 (atch- rule 6) indicates that there is no such strap near the offending transistor While 30 um is the maximum distance, it is encouraged to place a strap, or perhaps an entire guard ring, as close as possible to the transistor
  • EMI Line Filter Damping - Electrical Engineering Stack Exchange
    An EMI filter is made of several energy-storing elements - inductors and capacitors - combined together to provide an attenuation at a certain frequency These elements are not perfect considering the parasitics they host For instance, the equivalent series resistance (ESR) of the capacitor or the dc resistance (DCR) of the inductor incur losses when rms current flows Similarly, dielectric
  • How do I debug Modbus timeout error? - Electrical Engineering Stack . . .
    This is about product usage, not about electrical engineering Can you get support from manufacturer? Are you sure your product was bought with 2-wire Modbus option? Are you sure you don't have A and B wires swapped (try it)? Are you sure the product is not expecting a 4-wire Modbus? Frankly, there is not much to debug - timeout happens because PC receives nothing, but it might be because the
  • summing - How do you combine 2 AC power sources? - Electrical . . .
    To combine 2 DC power sources, you can diode OR them both together You can't just directly connect them together because their voltage outputs may differ ever-so-slightly, leading to imbalanced cu
  • Adding an IC to LTspice - Electrical Engineering Stack Exchange
    If the example works, examine the symbol in it very carefully I believe there are two places to enter it In the symbol properties within the schematic it is used in and after you open up the symbol file itself in the editor where you first created the symbol I forget if you need to enter it in both places or just one
  • How to define trace widths for KiCADs freerouting autorouter
    I am pretty new to kicad, and hope i can find some advice here? (I could share the kicad example schematics too, if needed) I am having a this example schematics Here you see a power supply for 2
  • Powering a Small DC Motor with USB
    I am designing a device that uses a small 12V N20 geared motor For convenience, I would like to power my device via micro usb I intend to use a step-up boost converter to get from the supplied 5V
  • Input Output impedance for 4-20mA signals
    Hoping I can gain some clarity on an issue that I am having - We recently installed a new system to running a VFD controlled pump, controlled by a pressure transducer The pressure transducer we
  • RS485 collision detection - Electrical Engineering Stack Exchange
    RS485 is not a good choice if you don't have bus management protocol I'd suggest to either implement that (could be as simple as time slicing) or use CAN for its native collision handling Just how many nodes do you have? If only two then full-duplex transport protocol is the simplest solution
  • pcb - Incomprehensible ratsnest in Kicad - Electrical Engineering Stack . . .
    In PCBnew, there is a ratsnest that I cannot comprehend why its there This is it: As you can see, there is supposedly connection between pins 3 and 4 However, if you look at the schematic, pad 4
