Question re - RJ45 w/LEDs

$

0

A google search for fritzing part rj45 turns up some hits (which may or may not have leds.) Your best bet would be to select the part you want to use and then look for a Fritzing part that matches the data sheet (as I don’t know if the led pin outs are standard or not.) The LEDs should be in the data sheet for the part (assuming it has a data sheet of courses, some of the ebay et. al. ones probably don’t.) Otherwise they should be standard leds that want between 5 and 20ma to light (the data sheet should give a max current and possibly a suggested current.) If you can’t find a part and do have a pin out you need it is easy enough to make a new part.

Hi!
I don’t have any experience with .svg files, but my friend made me some files representing the Elechouse version of the PN532 for me to use for a school project. I have searched quite some time for this part and found that other people have also searched for this. It is probably far from perfect, so I suggest that someone updates and reposts it, but it does the job for me and I hope that I can make other people happy with it:) Many thanks to Wesley!

Yes, strange. My source is DigiKey. The datasheets contain a lot of information (even LED polarity) but no mention of forward voltage, ma’s …

OK, I found one set of specs on page2 ,

LED forward DC current: 20mA typical
LED forward Voltage: 1.9 Volts max. @ 2mA (for single colors)
2.6 Volts max. @ 20mA (for Bi-colors)
LED reverse voltage: 5 Volts minimum
LED light intensity: 0.4 to 1.5 mcd @ 2mA (for single colors)
0.5 mcd min. @ 2mA (for Bi-colors)
LED wave length: Yellow: 587± 7 nm measured @ 20mA
Green: 565± 6 nm measured @ 20mA
Red: 625± 5 nm measured @ 20mA

I think I got this.

Not a bad job, but a few problems. First the svgs are dimensioned in px, inches or mm is a better bet as Fritzing will guess at which of the 3 dpis was in use and often (and perhaps in this case) gets it wrong. That said the dimensions on your part appear wrong, and there isn’t enough information available for me to correct it. The pin spacing appears to be 1.9m (it probably should be 2mm), and the board shows as 1621mm where the data sheet says it should be 2128mm. I left the dimensions as they are because I don’t have one of these boards to compare. In pcb I copied in the breadboard image and set the silkscreen to have the same (incorrect) dimensions, and added the two mounting holes in silkscreen (they won’t be drilled, if the user wants the holes they need to drag a hole in to the sketch and position it over the hole in silkscreen.)
Schematic had a number of problems: missing terminalIds which causes this:

the wire is terminating in the middle of the pin because there is not a terminalId defined at the end of the pin. As well the pins are not on a .1 boundary (which may be because of dimensions being in px). In the fzp file I removed the terminalId definitions from the breadboard layer (they are not defined and not needed in this case) and changed the type from female to male (which is the usual.) All of that is done in this part except as noted the pin pitch and board sizes appear incorrect.

I’d guess that 2ma is the usual run current and 20ma is the max. Try one at 2ma and see if the leds are bright enough for what you need. If you can find a Fritzing part that matches the footprint, you can use that. If there isn’t one, if you post the datasheet I can modify a part to match.

RAMPS 1.4 PARA arduino Maga 2560

Here is a ramps1.4 part. It doesn’t have pcb (it isn’t useful, and has been suppressed), and doesn’t have the mega connections (although I have included the eagle2fritzing part below if someone wants to add the mega pins, which will be a lot of work.) You can drag one of the A4988 boards (one isn’t correct and won’t fit) over the pins on the ramps and it will mostly connect in schematic, but some of the bus connections don’t complete correctly (perhaps a Fritzing bug.)

Steps I took that resulted in the problem:

Trying ti install Fritzing receive error missing LIB.

What I expected should have happened instead:

Install the purchased product.

My version of Fritzing and my operating system:

Just paid and downloaded Fritzing package for linus and using Ubuntu 18.04 with qt5 installed.

Please also attach any files that help explaining this problem

It would be more useful if you had indicated what library is missing … That said, 0,9.4 does not include all the libraries (as 0.9.3 did) so have you done

On Ubuntu, those can be installed with “sudo apt install libqt5printsupport5 libqt5xml5 libqt5sql5 libqt5serialport5 libqt5sql5-sqlite”.

from the install page? If so what libraries is it complaining about?

20x TIP120 - Solenoid Array

Hi there,

This is my first PCB and first time using Fritzing. I am trying to create a simple Transistor array to drive a series of mini 5v solenoids using an Arduino Due. The final layout will have 2 of these boards for a total for 40 solenoids.

I have drawn the schematics first, but now that I am routing the PCB I am getting all sorts of weird connections, which makes me think the schematics is wrong. Could you please have a look and let me know if you can see anything odd?

Many thanks!

Schematic text notations (for voltage notes, etc.)

I am aware of the “Edit>note” method but that gives a very large font in an overbearing yellow box and I need something about the same font size as the other labels on the components.

The text box from the core window seems promising as to font size if I could figure out how to edit the text… When I drag that box onto the schematic it contains the word “logo” and i can’t find a way to change that text.

Any ideas?

Thanks
Frank

I don’t see any problem, what you are seeing is the rats nest lines formed by the connections in schematic. If you double click on a rats nest line it will create a trace. Once the trace exists you can click on it and drag it to where it needs to be to make the routing work. Here I have double clicked on one rats nest line in pcb to create a trace:

As it stands it is difficult to route the trace because Fritzing will select and create one of the other rats nest lines. So click View->Ratsnestlayer which deletes the rats nest lines from the view for the moment and then click on the trace and drag it to the correct position like this:

Of note here is the two end pads are green rather than red, which indicates you have the net properly connected (red would indicate the trace is not complete, which may happen if you click on an end point and drag the resulting trace to a new end point, clicking on the rats nest lines is a better bet.) Now click View->Ratsnestlayer to show the rats nest lines again and do the next connection. If you (as I often do) get two rats nest lines, you can right click on the trace and then Delete to delete the wire, or just drag it out of the way and route the original trace, then do the second one when the first is done. The thing to avoid is making changes in more than one view (i.e. schematic and pcb) because if you short two connections together that shouldn’t be connected you can corrupt the routing database unrecoverably and have to delete all the traces (sometimes in all views) and start the sketch again. Best practice is what you look to have done, finish one view (schematic in this case), then take a backup copy of it for safety in case you screw up, then move on to the other two views and click on rats nest lines as they are showing the correct connections (i.e. don’t route traces where you think they should go as you may create shorts as noted.) Once you have the board routed, you should export the gerber files (File->export-> for production->Extended gerber) and use a gerber viewer such as gerbv to verify the gerbers are correct (there are some Fritzing bugs which will look fine in Fritzing but generate invalid gerbers.) If you post the finished fzz file I’d be happy to look it over for you.

Click on the text in schematic to select it, then in Inspector (lower right window) there is a field called text (with logo in the field) changing that changes the text. You can also change the font size by changing the poorly named shape field below it. Inspector will change many things about parts in the sketch. You could (with a lot more work) also load svg images with the schematic image icon if you want a particular format.

20x TIP120 - Solenoid Array

Thanks so much for your help Peter, and for taking the time to write all that!
As you described I was having some issues with the rats nest. I ended up deleting all the diodes and adding them again and now it’s all fine.

If you have a moment could you have a look at the final design (attached), before I send it off for prototyping? I hope the connections around the solenoids and diodes are correct… I am not sure the circuit was right in the first place.

I also read you should add capacitors to make the signal more robust, but I am not sure where they should go and which type. Any ideas? (I am planning to use mini 5v solenoids with a separate power supply).

Thanks! G

The pcb looks fine as is, but improvements are possible, advisable and easy to make at this point. The first item to consider is how much current the solenoids draw because there are a lot of them. The catcher diodes look fine (you may want to upgrade to schottky diodes from the 1n4001s though, schottkys are faster and have a lower forward voltage.) The idea of the diodes is to supress the back emf when the coil disconnects. It will raise the voltage (in the opposite direction to the applied voltage) attempting to keep the current constant. The diodes provide a path to discharge that energy. I would add a high current schottky diode in series with the 5V supply to the coils with a 100uf bypass capacitor to ground after the diode. The capacitor provides initial inrush current local to the solenoids. The diode protects the logic which presumably shares the 5V power supply from voltage spikes from the coils (if the 5V line on the coils gets above 5v, the series diode will shut off and not allow it to drag the external 5V line above 5V.) Next you need to figure out what the hold current for the solenoids is as that affects both the drive needed for the transistors and the size of traces on the pcb. If it is only 100ma (which is likely to the low side) 20 solenoids take 2A which is getting a little high for .1 connectors (typically 3A max current), screw terminals may be a better bet. If the solenoids are 500ma each we are looking at 10A worst case (all solenoids on) and need to move to high current rules. I see I may be under estimating currents here, a Adafruit small 5v olenoid shows 1.1A draw at 5V, which puts you well in to high current rules. In this case the signal robustness only deals with ground (because the transistor drive is only referenced to ground) so some changes to the ground configuration are all that is needed. You want to have one of the ground pins dedicated to driver ground and be independent (at least on this board) of the solenoid grounds (the connection between the two grounds needs to be at the microprocessor. Because the transistors are darlington you have 1.4 volts of noise margin and thus not a lot to worry about, but a separate ground is still a good idea (the issue being voltage drop in a high current trace will erode your driver noise margin so you want a ground trace that doesn’t carry significant current so as to preserve noise margin.) The place to start is with the steady state current of an activated solenoid because that drives a lot of the rest of the calculations and considerations. Then I would consider powering the solenoids via screw terminals (which can take multiple amps unlike a .1 header) and separating the power and ground for each bank of 10 solenoids to reduce the current in any one trace (and use larger traces for the solenoid power and ground traces.) How much of that is needed depends on the current draw of the solenoids.

While there appears to be one (there are pictures) it doesn’t look to be available. So this should do. Note it is sized from a jpg image so position of the mounting holes in pcb may be not quite correct but otherwise it should be fine. As usual if you want the mounting holes, you need to drag a hole in to your sketch and position it over the hole in silkscreen, by default the mounting holes will not be drilled.

I don’t see anything that looks like the inspector you describe. I have a text box with “logo” in it, but I have tried everything I know to find the inspector but no luck. I even tried starting a completely new project but same problem

Sometimes when “adding a note” I have to zoom out to find the edit box, but that does not reveal the inspector for the “logo” text box. .

My next step is to upgrade from V9.3 to the newest version (V 9.4?) when I get a chance.

I’d love to hear any other ideas.

Thanks,
Frank

Ah! Learned something new. It is possible to suppress Inspector. Your screen should look like this (Inspector is outlined in blue)

but if you click the x (outlined in red), Inspector goes away to give you more screen room and is remembered in the preferences file (which looks to be what you have done at some point, perhaps without realizing it)

To fix that click Window->Inspector to restore the Inspector window (you can do the same to the parts menu if you need more screen room.)

Fantastic, I don’t know how you figured it out, but you did it.

And thanks for taking the additional time to post pictures.

I owe you one (probably two).

Thanks for hanging in with me.

You are most welcome. Others will probably also learn from it. As usual, trial and error is the way forward, you had obviously suppressed Inspector somehow, and the x is there. One it was gone there had to be a way to get it back and a search of the tool bar found that. Many things are poorly documented and passed along in here, this is just one more … We need to attract someone capable of doing documentation as well as developers but are having little success with either so far.
