Learn how to install the new and improved KiCad on Ubuntu and then build a simple microcontroller board to blink an RGB LED.  KiCad is a very powerful, fully open-source electronics design program that is getting better every day. In , as part of their Open Hardware Initiative, CERN began contributing both expert development skills and funding for some really great features. It's also been used for very complicated professional products such as the HackRF One, Ubertooth One, Smoothieboard CNC controller, and many more. In the spirit of open-source, this tutorial will focus on getting a working installation of KiCad on Ubuntu and creating a simple microcontroller board for use in future electronics proj. KiCad.

You won't even have to worry about the various PCB options, it's all pre-configured for you! Many thanks to all who have donated. I understand you want to make some money, but please note that you are getting this all for free. I would suggest using sockets for all ICs.

Another difference is the manual below setups your environment to use local footprint libraries instead of ones stored in Github. If you meet any problems - please let me know. I would rather make KiCad easy to build for everyone than force you to use tricks.

You may need a few libraries to start messing with hardware design or you may draw them yourself, then skip the part below. Optionally, you may set up eeschema to you a custom folder instead of installing the library. You may install it in a similar manner to symbol libraries, but these files are not critical to be placed in a specific location.

Just downlaod the contents and store it wherever you like read that as well! Page history. Libraries You may need a few libraries to start messing with hardware design or you may draw them yourself, then skip the part below. Make sure to wire it properly Info soon. Oh, I have no idea if the line filter can be bought new, so you'd better recover that, too. Other things you will need to recover are all the custom Commodore ICs, of course.

Make sure you are using an Agnus, and populate C99 accordingly. CPUs can be found second-hand cheaply. Every serious electronics shop should have all the series chips. I would suggest using sockets for all ICs. Get new good-quality ones. Be careful with the RAM chips: if you socket them, they will probably be too tall for the keyboard to fit properly.

Probably you will also need to recover the original quartz, as it has an uncommon frequency PAL: You can recover the original Video Hybrid, or you can build a new one.

The solder jumpers should all be preset with the most common value Detailed info on these will be added soon. If you use the standard MSMB Real-Time Clock, you will need to calibrate the clock frequency through the TC9 variable cap, which requires the use of an oscilloscope.

If you decide to recycle it from an old board, try not to move it during the desoldering. You'd better mark its original position with a marker before removing it. In this case, do not install Y9, C, TC9. You should also put a blob of solder on JP9 so that the system will pick up the one that might be present on a card inserted in the trapdoor slot in this case you can also skip R The battery holder is called BS-7 and is very easy to find.

Other ones will probably fit just as nicely. Make sure to use a NON-rechargeable battery. If you want to get this board produced, you are recommended to get the latest release rather than the current git version, as the latter might be under development and is not guaranteed to be working. Every release is accompanied by its Bill Of Materials BOM file and any relevant notes about it, which you are recommended to read carefully.

I am not providing ready-to-use gerber files. If all you want is to get boards made, I would really appreciate if you did so in a way that supports the project.

I am not sure I can claim any copyright on this, as the actual schematics this is based on belong to Commodore or whoever has that right now, definitely not me. So the claim below is going to be more of a declaration of intent, in the sense that I would like that everything that uses my work stays open and free.

We expressly disclaim any liability whatsoever for any direct, indirect, consequential, incidental or special damages, including, without limitation, lost revenues, lost profits, losses resulting from business interruption or loss of data, regardless of the form of action or legal theory under which the liability may be asserted, even if advised of the possibility or likelihood of such damages.

The contact points for information about manufactured Products see section 4. Any modifications made by Licensees see section 3. The license allows you to sell these boards. I have nothing against that as long as you do so at an "ethical" price.

I understand you want to make some money, but please note that you are getting this all for free. You had no development costs and you invested no time in this project. This amount has been set in April and will be updated, should the value of the Euro vary significantly. Also, please do not remove the credits, URL and license statement.

There is no reason do so , you have the right to sell this board, there is no need to pretend you got it somewhere else. Ironically, If you removed those, you'd lose that right as you'd be violating the license terms. You get my gratitude and cheap, professionally-made and good quality PCBs, I get some credit that will help with this and other projects.

You won't even have to worry about the various PCB options, it's all pre-configured for you! Also, if you still have to register, you can use this link to get some bonus initial credit and yield me some more. If you need help or have any questions or suggestions, you can join OpenRetroWorks on FreeNode through your favorite IRC client or the webchat , or the official Telegram group. Skip to content.

Differences from original The initial objective was to come up with a new mainboard as similar to the original one as possible, while including minor modifications that would improve its usability.

This makes them easier to solder and more solid to the board should you need to rework them. This forced a few tracks running very close to the original pads to be slightly offset away. Leave unpopulated for others only will work. The floppy connector footprint was changed to that of a full IDC connector. A simple floppy drive switcher was integrated, just below the floppy connector.

The barrel battery was replaced with a BS-7 battery holder for a normal non-rechargeable CR battery.
