Making good progress on v2 update and thought I’d share some early progress. The PCB work has been completed for the most part. Multiple PCB can be created as a single assembly(SBC) using different shapes(rectangle, polygon, round, dxf extrusion), each with it’s own unlimited holes, SOC, and components; placed anywhere in space. In addition, the same shapes can be used to add or subtract geometry to or from any of the PCB in the SBC.

      There are four PCB of different color in this test SBC example. Each uses a different shape with the Black PCB also deploying the PCB additive and subtraction commands, a practical design as you can see.

      Now you might be thinking hey, SBC stand’s for SINGLE board computer, but there are SBC like the AtomicPi that use multiple PCB. This approach also supports another use that this project is dedicated to, micro-controllers. There are many standards that stack ‘feather’,‘pico’,’tiny’ style boards on top of one another. Likewise, I was contacted by someone who was interested in using this project for a modular IOT system. These are all target uses that make sense for this project and will make for an even wider utilization of SBC Case Builder once implemented. And speaking of things being completed, the following items marked with a hyphen are complete.

      Version 2 Update Status

      Uncompleted

      Code: Select all

      Component Library
         Component Variable Height Adjustment
         Auto SBC Mask Generation
         Component Variable Mask Depth
         Standardization, Additions and Cleanup
      Compute Modules and Carrier Boards
      Even though I made good progress with the first number of items, the uncompleted areas are all related and are going to take some time to get through because there is a lot of work to be done. I need to spend time standardizing the library and creating a bunch of new parametric and dynamic components. One of the many problems I was not been able to solve with version 1 is the variation in component height, the IR sensor is a great example. They vary from SBC to SBC even within any given manufacturer’s product line.

      When I started planning for autonomous I/O openings I wanted to put the masks in the component library but could not. I had to create a temporary method in SBC Case Builder until SBC Model Framework could be updated. The goal now is to have every component in the library also contain it’s own mask for it’s opening profile. Moving the masks to SBC Model Framework will also solve a host of issues like synchronizing and registering the component model with the component mask and simplify the creation of new components. It will significantly simplify and reduce the amount of code in SBC Case Builder because it will no longer have to mange or create SBC component mask sets.

      There is another advantage as well for anyone using this SBC library. It will not only contain SBC models but also the mask sets for every SBC in the library. This will allow anyone to easily create registered openings in their own designs by simply performing a ‘difference’ between their geometry and the called SBC mask set...Wala, perfectly registered openings for your design.

      It is my goal not only to have every component in the SBC Model Framework Library be self-informed, but also every accessory model in SBC Case Builder, for a simple and cohesive autonomous design. This will be accomplish by embedding critical data and resources within each application layer of the model...more on this later.

      Since the Odroid-H3 has a different heatsink, which is slightly larger in the x and y axis then the H2’s, a separate H3 model has been added in release 1.0.9.

          Making more progress, the mask migration to the component level has been completed for existing use class components. Each component now has a 3D model and one or more mask openings that can be called. The choice of different masks will be helpful in many situations e.g. access to micro sdcards were one could have a slot or a block opening in the case for easier access.

              The length of the mask and set back from the face of the component is variable and can be changed for each instance of a given component for a SBC. Variable length masks give the maximum case opening flexibility and with an adjustable setback, accommodates larger component overhangs that might project into or thru the case sidewall. It was previously fixed at 2mm which worked well until I recently came across a SBC that had twin vertical HDMI ports with a 3.75mm cantilever. This approach removes any future potential problem and gives maximum control to handle outliers.

              More component work is still needed with several new component types yet to be created. Much of the original code base has changed and a significant amount of time was been spent improving the library organization and it’s code. The library was getting too large to effectively manage as a single file so I have broken it into separate files by component use class. It’s much easier to work with and will be easier to add future components, as well as maintain.

                  I’m at a point were the conversion of the current SBC in the library to version 2 is simultaneously underway with approximately 45 more to go. I have a few new SBC I will add too, one that wasn’t possible in the past, as well as some microcontrollers and compute modules. The hardest part so far has been trying to find the right PCB color for each Odroid model...I’m still working on it. :)

                      Hi great job, really impressive!

                      I'm struggling in exporting the Odroid M1 to STP though and I'm really not familiar with scad. I had "some" success in exporting an STL but I cannot really use it within my cad unfortunately, it needs to be a proper body.

                      Any chance you can post a STP file of M1 WITHOUT the heatsink? If you know of any alternative 3D models for M1 please let me know, I didn't find any

                      Thanks a lot!

                      OpenSCAD cannot export to STEP directly but another user was using FreeCAD to convert to STEP. I also have no way of verifying a STEP model either.

                      unfortunately that doesn't seem to work anymore with the latest versions, at least not on Mac. Loads of errors when I try to open the scad in Freecad..

                      Hopefully that user is still monitoring this thread because otherwise I'm stuck..

                      Update: managed to remove the heatsink now and at least I got the STL model of the board alone. I'll see if I can convert it to stop some other way

                      I'm sorry, I thought you knew there was a "m1_noheatsink" in SBC Model Framework and were just specifying which one you needed converted. The m1 without a heatsink (and n2+_noheatsink) has been on the main branch for a little while but I'm not sure if it is in the release attached in this thread. FYI, When I tried in the past I never had any success using FreeCAD to convert to STEP either, so it must have stopped working awhile ago. I even considered writing a STEP converter at one time but one has to be an association member to get the specification and I never found a copy anywhere else on the internet. If you figure out a way to convert these to STEP please let me know.

                      After spending time on some other projects I’m back working on version 2 of this SBC library. Historically new releases have been posted here when a new HK board is released but since there have been some fixes and many other sbc added, it makes sense to post a version 1 update now. The library and stl’s have been updated to version 1.0.11 in the OP.

                      Development wise for v2, I finally trudged thru the conversion of the existing SBC to the upgraded format. SBC that couldn’t be properly supported in version 1 have been corrected and new complex and multi-PCB SBCs can now be added. Several new components have been introduced to the library along with an ongoing optimization effort.

                          The library has been redesigned and divided up into two categories, use and object, which is determined by whether an I/O mask opening is used by a component. Version 2 contains all I/O mask openings as part of the component definition and can be used by other applications and software. Likewise, all components in the library are being restructured as parametric components when possible. This is taking more time then originally thought but it’s worth it in order to reduce code size, speed rendering and ultimately make it easier to use.

                          More time is also being spent to make the SBC more aesthetically accurate too. For example, pins are being added to discrete components as well as copper around PCB openings, just to name a couple of the aesthetic improvements. I believe the current new SBC I’m working on, a 2 PCB assembly, is number 62. I also have others I’m considering adding, including several micro-controllers and compute modules, before verson 2 is released.

                          Indeed, looks like a museum showing ODROID history. :D

                          At the beginning of this project I tried to find data to recreate the whole historical HK line going back to the Odroid-X, XU, W and earlier but couldn't pull enough data together to reproduce them. Maybe I'll come across one or more of them in the future.

                          Thanks everyone for the continuing support!

                          The SBC I’m working with uses three different header pitches(1mm, 2mm, 2.54mm) . In the past, using static parts would require a separate module for each one by pitch and pin count. With the version 2 library format, parametric symmetrical pin headers can be generated for any pitch and pin count in thruhole or smt.

                              Provisions were made to accommodate for row or column precedence e.g. 1x6 or 6x1, which particularly effects smt lead orientation and placement. This helps avoid rotations for 90 degree header placements. The datasheets examined for 2.54 pitch headers listed the smt body width at 2.5mm instead of 2.54mm which accounts for the code discrimination. Box and angled headers aren’t needed right now so those will be completed later.

                              The code above is the test file that I used to develop the header module. It allows for easy testing of all the possible component configurations. This is especially useful when developing parametric parts that will have many incarnations. For anyone interested, one can copy the above code into Openscad and it should render into the same components as shown above.

                              Now none of this is particularly complicated, but with the growing interest in OpenSCAD, sharing and examining code is one of the ways I’ve learned in the past and maybe others will be interested too. JST connectors are next to be worked on and currently there are individual modules for XH, PH, ZH, SH that will need to be combined into a parametric algorithm. A new connector type needs to be added as well, JST-PA. All of this will be more challenging and require a different approach then the header module.

                              The Odroid-M1S has been added to the library. The mechanical drawings and STEP model posted at the Wiki were used to create the model. The HK STEP model was converted to a stl and used as an overly to verify component registration. It should be good to go but I’ll check it against the real thing once one is in hand.

                                  The library and stl’s have been updated to version 1.0.12 in the OP.

                                  The JST module is complete and it had a few moving parts but wasn’t to bad. There are 4 inputs needed for calling the module: JST type(XH,PH,ZH,SH,PA), #pins, mount(thruhole or smt), and entry(top or side).

                                      After a study of the relevant data sheets for each JST type it was clear that a method was needed to lookup different data sets, so an array was created for that purpose. I’ll be using this method or a variation of it for other components as well. It makes it easy to accommodate their differences and add new components to the module as needed.

                                      Things moved along this weekend so I also spent some time on other components like b2b and fpc connectors and got a good start on compute modules. The b2b module produces .4 pitch receptacles and plugs for any pin count and stacking height. All three of the standard CM forms are now present and a supporting carrier IO board is nearing completion.

                                      That's what I was worried about, that JST may not follow clear patterns across their different sizes. LUT complicated things but it looks reasonably easy to expand in the future.

                                      Re: SBC Model Framework

                                      Post by hominoid »

                                      There is a new release of SBC Model Framework, version 2.0. This version features expanded PCB shape support, unlimited components with component based mask generation including heatsink, GPIO and UART masks. The module call includes the ability to turn on or off the heatsink, as well as the GPIO to support the increasing number of SBC offered without GPIO headers installed. The masks can be controlled from the call allowing for the selection of the default or one of the other masks available for heastsinks, GPIO and UART.

                                      Total Devices: 84
                                      SBC: 69
                                      Carrier Boards: 3
                                      Compute Modules: 8
                                      Micro Controllers: 4

                                      The monolithic code base of version 1 has been broken up with extensive cleanup and standardization. Many new components were added increasing the number of component classes from 17 to 35 with many containing parametric components. A viewer has been created as well which allows for individual SBC to be examined along with their technical specifications. Additionally, 2D sections can be created for downstream use. The generation of the sections can take several minutes even on a fast machine so be patient. A 3D SBC Model Framework Reference Manual is also available thru the viewer. It displays all Class and Types with their corresponding models. The thread’s text, documentation and source files have been update in the op.
