The exported SPICE netlist file cannot be successfully simulated
When I simulate the circuit using KiCAD V7.99, it is successful. However, when I export the netlist file and simulate it using the ngspice, the simulation fails. Steps for ngspice simulation: 1.

Locked Reverification
I just received an email from groups.io to say that, because one of their servers had been labelled as a spam sender by anti-spam service spamhaus, some members of the group will have to reverify

Re: All components in schematic becomes slightly displaced
And also use this 50 mil grid when building new components, otherwise, the same "error" will occur.

Re: All components in schematic becomes slightly displaced
Thank you Steve! After finding this alignment tool I updated my grid settings to 0.05" and realigned everything. It was set one step smaller. I don't seem to have lost any connections when doing this

Re: All components in schematic becomes slightly displaced
Please check your grid settings (View menu -> Grid Properties). I recommend using 0.05 inches (1.27 mm) because the components in the libraries are all aligned on that grid. If you have it set very

Re: All components in schematic becomes slightly displaced
Thank you Tony (and the others of course!) How could I miss that option? I really looked for something similar... Anyway, now I'm back on track again :o)

Select everything on the schematic. Place cursor over an object, Right-click > Align elements to grid. -- Regards, Tony

Re: All components in schematic becomes slightly displaced
When I used to use Cadence Capture two things could cause this... * The first was if you changed snap to grid to free form... * The other was if you used a very small grid and switched from mils to

Re: All components in schematic becomes slightly displaced
Never noticed that behaviour. Maybe have a look at the source file to see if the coordinates of all components are off grid? Or maybe there is a (accidental) keyboard shortcut to set the grid to a

All components in schematic becomes slightly displaced
I have a reoccurring problem. From time to time all components and wires are slightly displaced on the grid making attaching new wires to the pins impossible without realigning everything one

Re: Minimum Track Width for Very Long Tracks
Interesting Steve, although it is now way past being even historical, but when did this higher voltage version become available? My unpleasant run-in with it was in the latter half of the 90's and

Re: Minimum Track Width for Very Long Tracks
If you are trying to drive I2C over long distances, consider using a PCA9600 on each end of the run.? It is a lot harder to blow up than some other buffer chips (e.g. PCA9617).? You can also use

Re: Minimum Track Width for Very Long Tracks
Unless you're getting your board made in Joe's workshop under the railway arches, you shouldn't need to worry about the manufacturability of boards with 0.2mm tracks. They're routinely used in PC

Tell that to a now defunct maker of a quite expensive device used to synchronize a satellite signal which may have doppler effects from the satellite drifting around in its orbital "box" that takes

Re: Minimum Track Width for Very Long Tracks
This is all going very off-topic, but I understand the main problem is ending up with edges on the I2C bus that have an RC time constant that is too slow, so one needs to drop the pull-up resistance,

Re: Minimum Track Width for Very Long Tracks
Yeah, but if you have a 'transmission line' you would avoid needing to vary the track width or doing other things to create impedance bumps. And using I2C to go 40-50 feet is taking it way beyond

Re: Anyone made a symbol/footprint for Sparkfun Micromod carriers?
Sorry Gene, I was attempting to start a new discussion. Is there more context required? I'll expand a bit more in case that's helpful. If you are not familiar with the "MicroMod" system it combines a
