Backstory on the PIC: the picture is of a MELD-X driver from tterev3. A while back, he said he doesn’t mind if people copy his board designs and/or build new ones based off his. He only cares to keep the PIC firmware to himself. So, I was planning to make a new driver board to fit in a specific light and never got around to it. Now, I’m trying to get started again, and I need the PIC footprint for the PCB.
I have that part in Eagle…
Pretty sure tterev3 made the eagle footprint I use, that’s his driver, did you ask him if he happens to have it for KiCAD too?
Edit to reply to the post you made at the same time as I made this one: what light? I have MLED board designs for several different lights.
ATTiny85. Perhaps calling it a PIC is a misnomer.
No, I didn’t ask tterev3. I just decided to try KiCAD again a couple days ago, and I hadn’t got that far yet.
I originally was going to make one for TheOnlyDocc for his Wall-E light. but he was having trouble with other mods he was trying to make, and never did get me the measurements. (yet?) Now I have a light that I won from gchart’s giveaway here. It is a Brinyte B21 Complex and he did a review of it here but he said he thought it was a pre-production sample, so may not be exactly like the final one they eventually introduce to market. I have two MELD-X drivers from tterev3 so I can use one as a donor for a new driver if it is anything weird. I haven’t opened it yet to see the driver.
OOOPS, I just realized that CK was talking to sbslider. Even quoted text. :person_facepalming:
Hey man, our convo was relevant too lol 
I haven’t used KiCAD but the PIC16F1575 is just a standard QFN-16 4x4 package that I’m sure exists in some standard libraries. If my Eagle files can be of any help let me know.
Thanks for the offer tterev3! Yeah, if you would give me the Eagle schematic I could take it from there. I was just trying to get started with KiCAD here but it seems KiCAD has too much learning curve still for me, especially since it lacks libraries for some of the common parts we use for drivers.
I only know of it because I have played with the mechanical design software, but I thought I would throw out an alternative program: DesignSpark PCB
Here’s the board and schematic files. I think these will let you copy the microcontroller part without needing the whole library. If that doesn’t work let me know
Thanks! That should be enough.
Inspired from David from another thread today I tried to make AMC7135 Kicad symbol model for it. Also it use the SOT-89-3 layout from standart Kicad Footprint Library. In library are there 2 components AMC7135 and AMC7135_H. Second is with larger thermal pad for easy handsoldering linked also to SOT-89-3 Handsoldeirng footprint. If you have any suggestions I will try to make the changes to library components or if something is missing from standart libraries I will try to make model for it.
Some update to Kicad. First try to make BLF style driver with Kicad following Youtube BLF Eagle tutorial. There are some limitations and peculiarity when is need to draw arc track and circles. Kicad lacks in that area with violations with DRC but is possible to draw track with attentions and if you ignore some errors. This is main limitation of Kicad compared to another PCB software. You can't assign directly circles and arcs to net if you compared to Eagle. But with some workarounds it is possible. In the future 6 version there will be support for that. One of the developers of Kicad now work on that.
Would you mind sharing your KiCAD “BLF style driver” files here? I’d like to take a look at them so I can learn how to use KiCAD for my own driver designs. Also, I forgot to say earlier, Thanks for sharing the AMC7135 parts library you created.
I will share no problem. Here in the forum I see many peoples are shared their PCB designs on OSHPark over the years but is very rare somone to share the source files which is sad.
Here is the link https://drive.google.com/open?id=1FrxcPWQtLCmpyDWeKdwofKPlUFzMreBi
Hi David I edit a little bit footprint for 7135 in my design to make smaller on board. Standard footprints for SOT-89 are a little big. I used that datasheet for reference to footprint https://www.diodes.com/assets/Package-Files/SOT89.pdf
Kicad footprint libraries are with extension “pretty”. Here is very good explanations of Kicad file structure of libraries https://forum.kicad.info/t/library-management-in-kicad-version-5/14636
Also there is great tutorial to make custom footprint https://forum.kicad.info/t/tutorial-how-to-make-a-footprint-from-scratch/11092
It is no very difficult at all, also is fun to make your own parts 
.
Oshpark accepts KiCAD and Eagle design files directly. I have always uploaded my Eagle BRD file, which is the “source” of the actual PCB design. Eagle also has a circuit diagram file, but OSH Park doesn’t care about it so I never included it. Some members don’t even bother to make the circuit diagram, preferring to “wing it” with the PCB design. I don’t know about KiCAD files, what info they include. But I think a PCB design file should be enough for most people who might want to make a derivative work. It’s pretty easy with the mostly simple driver designs we use around here to reverse engineer them to make a circuit diagram if needed. For the members that don’t share their “source” files, I guess they have a good reason. But yeah, I think it’s a bit sad too. 
It is possible to download uploaded and shared files from OSH Park? I don’t see any option for that.
In Russia from years they use same approach for direct drawing of PCB but most people there use the Sprint Layout. It is not like a CAD program. It is oriented to hobbyists like most people here. And yes it is very easy if you want to make reverse engineering schematic of PCB.
Yes, downloading is very easy. On the project page, you see a description on the left side, and two “preview” pictures on the right side. In case you don’t know, if you click either of the pictures, you will get a full size image, which you can also “download” or “save” to your computer. But, under the pictures, there is a link that says “Download”. You just click that and it will give you all of the files that have been uploaded for that project by the creator. Every shared OSH Park project has this Download link. The only way to disable it is to not share your project at all. If the project can be viewed, then it has been shared, and it can be downloaded this way.
EDIT: Oh yeah, the “Download” button is right next to the “Order Board” button.
Thanks David for explanation. I didn’t noticed that option for Download until today.
