I generally do not change the layer colors unless I have to. Did you catch it? However, the speed and efficiency of KiCad really shines when muscle memory kicks in so start memorizing. When I open this project on my laptop, it will first look for the files in the "C:\Users\nathan.seidle..." location. For example, let's say that you wanted to remove an extra capacitor or resistor from a design. Press 'a' to add a device to the schematic. (If you are using a different tool you may need to click on the schematic as well): There are hundreds of components (668 items according to the title bar). Press 'b' to update the polygons. Check out the comments section for more info. KiCad will ask you where you want to save the netlist as a ** *.net** file with the default location being the project folder. Let's open an example! In development since 1992, KiCad has cemented itself as the premier Open Source PCB design suite, and since 2013 CERN has been making contributions to the project. Now we can click on 'File->Set Active Library'. This will open the component window. In the image below, we can see the stock schematic component libraries that ship with KiCad. From this view, turn off all the layers but the Top Copper (layer 5). The top paste layer is not needed to fabricate a PCB. Once KiCad's GerbView is open, click on File -> Load Gerber File. The footprint libraries table file (on Windows 10) is located in your AppData. It's a well documented system for creating community share-able footprints. If you are an EAGLE guru starting to get your feet wet with KiCad, be sure to checkout Lachlan's Eagle to KiCad converter for converting your Eagle PCB layouts to KiCad. Export the netlist by clicking the generate netlist button. This is where you'll have to make some tough decisions. This will make the review less cluttered. KiCad is getting quite a few updates and a lot of the tutorials are outdated, so I found you have to look at the official documentation to check the newest way â¦ This will help reduce solder bridging between pins. The photocell is just as common as it gets. We are able to then edit the footprint as needed. Click on the Annotate schematic components button. He is the best! When prompted 'Where do you wish the new libraries to be added', select 'To Global library configuration (visible to all projects)' and click 'Finish'. Welcome to PCB editing. Although the screen shots in this tutorial are taken on a Windows system, KiCad windows and dialog boxes will look similar on other operating systems. There are still two DRC error arrows left with the error indicating: "Pad near pad". Start by hovering over the new cap and press 'm' for move. In the KiCad version, the mask apertures look too big. We recommend you change this value to 0.1mm. Note: This tutorial was written using KiCad 4.0.6 on Windows 10. I find myself hitting escape twice a lot just to be sure I'm back in default state. v5 Workaround: Users attempting to use more up-to-date versions of KiCad will inevitably run into issues following this tutorial, step-by-step. Open the new directory by double clicking on it. Rip up the SCL and SDA lines to make some room. There are a handful of things wrong with this example. Use the default settings and simply click on Annotate button to confirm. Where is it? KiCAD is a free open source Electronic design software or electronic CAD software. If you think you are done routing a board but still show a few unconnected wires that you can't find, the DRC window will help you locate them. When located, click 'OK'. Be aware that the worksheet was written for KiCad 5.1.0. Most fab houses will use 0.1mm as their default as well. ... We are a YouTube channel who share DIY tutorials, projects, hacks on electronics. If something doesn't make sense that's ok, just take a moment to do a quick search. We'll also touch on library linking, editing, and creation. Here as an example we want to set up a bandpass filter that adds two Sallen-Key filters. In general, there are 8x layers you need to have a PCB fabricated: In the Plot window with the Plot format set for Gerber, be sure these Layers are checked: Additionally, click on 'Generate Drill File' button. ** *.pro** - Main project file to keep track of the file structure. Pcbnew Circuitboardboardeditor *.kicad_pcb GerbView Gerberviewer Alltheusualgerbers Bitmap2Component Convertbitmapimagesto componentsorfootprints *.lib, *.kicad_mod, *. Your mouse wheel does what you expect: Zoom In/Out and Pan by Clicking. Once in default state put your mouse pointer on top of the 3.3V marker on the 0.1uF cap. Enter the name of the project in âFile Nameâ, in this tutorial we will call it âtute1â. Or check out 10-part KiCad video series with Digi-Key and SparkFun as Shawn designs a simple 555 timer circuit for a badge, orders parts, and solders the badge together! Rename it to 'fp-lib-table'. We recommend using the ZOPT220x UV Sensor Breakout KiCad files as the starting point for your next project. Yes, you can click on the equivalent buttons. The amazing growth of KiCad installations over the past few years is a long time coming. Navigate to back to schematic and click on the 'Run CvPcb' button to associate components and footprints: If this is the first time you've run CvPcb you'll get this warning: Depending on how many libraries you have installed, this may take up to 30 seconds. This will cause it to create the footprint table with the KiCad defaults. Open the new folder by double clicking on it. There's nothing worse than troubleshooting a faulty product and asking yourself: "I've tried every rework and soldering trick in the book, is it the PCB that's bad?". KiCad can't read your Eagle schematic components but we have a solution for that in a later section. Simply click 'Cancel' in the manager window and the library manager will close without saving changes. If you really get stuck please use the comments section on the right. Let's get started! Are you doing SMD reflow? Select CP2104 from the list. Aha! If things go really wrong, you can always delete the 'fp-lib-table' file and restart KiCad. When generating the drill file for this design two files where generated: Non-plated through holes are holes on your PCB that do not have copper covering the vertical walls of the hole. And we're off to the races. Itâs used extensively by both hobbyists and professionals. We'll show you how to create your own schematic symbols in a bit. Now don't get too excited. KiCad is a free and really good alternative. When you've reached open ground press 'v' to create a via. Remember how to do that? KiCad's solder mask clearance has a default of 0.2mm per side. Now press 'm' over the 0.1uF cap in the way by moving it to the left. SparkFun has used this footprint for years and is comfortable with the design so let's change the Netclass clearance constraint. Click on PCB Calculator and the on the Electrical Spacing tab. If your pointer is over multiple items (as shown in the image below with the cursor over both the trace and capacitor), KiCad will pop up a menu to clarify your selection. Each project has its own connections to different file structures. Start by pressing 'x' and clicking on the start of the capacitor's air wire for GND again. We'll also export our PCB to gerbers so the board can be fabricated. Lets switch Canvas to OpenGL for now. It will fail and then search the relative path of "** ..\SparkFun-KiCad-Libraries**" and find the files. However, if you're using a more eclectic part, you may be better off creating the footprint from scratch. We changed things, so we need to import the netlist! We're going to assume you've already been through the previous sections of this tutorial; you should have KiCad downloaded and installed. Return to the main project window and double click the ** *.kicad_pcb** file. You'll want to overwrite the file that is there. We need to tell this project where to find the symbols for this schematic. KiCad will create the new 'LEDs.pretty' directory with a file 'C:\KiCadLibs\LEDs.pretty\LED_CREE-XHP50_12V.kicad_mod'. Press 'x', click on the capacitor's GND terminal, bring the trace out, and press 'v' to drop a via in this area. If you're like me and have schematic libraries shared across multiple computers, adding a "User defined search path" is helpful: In the image , I have "..\..\SparkFun-KiCad-Libraries" defined. Once you've removed most of the offending traces, you can begin routing by pressing 'x'. Saturn PCB Design, PCB Toolkit V7.8 1. Let's create a local directory to keep all our local footprints. At last! KiCad Resistor Footprint Format 1. If you're familiar with Eagle, it can be scary to think all the time spent creating footprints will be lost when switching to KiCad. Click on the 'Next >' button, select the directory we created (i.e. This is useful when you need to view a certain layer. This is sometimes required for advanced designs where thorough electrical isolation is needed. Simply press enter or click 'Generate' to confirm this screen. It should work fine. 2. Oh KiCad! (i.e. I don't like the layer colors! Here is where KiCad shines - the Filter works well. Click on the Place wire icon which is the forward-slash green icon on the right vertical bar of icons of the main window. Return to the main KiCad project window and open up GerbView by clicking on the button. Does the customer care about the ***.gtp** file or is that just extra? kicad_wks PCBCalculator Calculatorforcomponents,track width,electricalspacing,color codes,andmoreâ¦ None PlEditor Pagelayouteditor *.kicad_wks Note Create a new project: âFileâ -> âNewâ 4. Download the 'combined fp-lib-table' to a local folder. Let's poke around these libraries. Press enter again to run the DRC with the default settings. Do the vias line up with the top copper where they should? Click Preferences -> Footprint Libraries Manager. This is because KiCad is pinging all the KiCad github repos and pulling down 93 libraries. KiCad tutorial: generating Gerber and Drill files" by Qi Hardware KiCadHowTo wiki : Tutorials and help with using KiCad Transtronics wiki: Kicad : a tutorial for â¦ For this tutorial, please create a local folder called 'C:\KiCadLibs\' (or your platform's equivalent). The vias marked with red arrows are too close to the traces near by. Remember if you mess up, press 'Esc' once or twice to return to default. Click 'OK'. We don't have to re-create the footprint but by moving it over to a KiCad library. If you have not already, click on 'Select working library' to set the active library to CustomComponents. It's nowhere, sorry. I called my lib file 'CustomComponents.lib' so that I know these are mine. Your job is to double click on the footprint on the right that goes with the component in the middle. KiCad inherently reads Eagle footprints! Although KiCad (pronounced âKai-Cadâ like the head of the Bajoran clergy, not âKey-Cadâ like the thing that goes in a lock)is the new hotness when it comes to PCB design. Let's try removing the component that we just added in our custom library CustomComponents.lib. Once you've added the SparkFun schematic components library file, you should see it added to the list.
