BBC micro:bit CAD Resources - Kitronik University

This Kitronik University resource is part of the BBC micro:bit partnership and features FREE downloadable bbc micro:bit CAD resources.

The bbc micro:bit CAD resources:

The team here at Kitronik have created a CAD model of the BBC micro:bit. We use these models to produce many of the resources we create for the BBC microbit. We've put up these models for you to use free of charge for your own designs and renders.

Students and teachers (and home users) alike are sure to find them a good starting point for projects based around the BBB micro:bit. The files are available in the following formats (see bottom of page for download links):

  • .iges
  • .stl (which can be used in most CAD programs and for 3D printers)
  • .sat
  • .obj

This render was created to show the kind of images the files could be used to create.

Autodesk - FREE Educational Design Software

To use these files you will need some CAD software. Autodesk provides their professional software free of charge to Education and Home user which makes it an ideal choice. Autodesk gave the following reason for providing such easy access to its products:

'Closing the skills gap starts in education. Autodesk is tackling this by providing schools with common access to the same advanced technology being used by industry professionals today. Autodesk provides schools, students and teachers with free access to its professional 3D design software. This will enable educators to introduce design thinking into our classrooms allowing students to imagine, design and create a better world. Using these tools to learn how to solve real-world challenges in new creative ways will be the perfect preparation for our next-generation workforce. Equipping them with 21st-century skills to meet industry demands and advance economies worldwide.'

How Kitronik Are Using The BBC microbit Design

We're using this design to create new resources which we thought you'd find useful. One example is this poster highlighting the features of the BBC micro:bit (PDF download available below):

 

Also, another is this useful mechanical datasheet (download available below):

Using The Files When Creating 3D Printed Case Designs

Having the BBC micro:bit as a CAD object is incredibly useful when creating 3D printable (or laser cut-able) case designs. It means you can create your design with the knowledge that when you come to manufacturer the final design the BBC microbit should fit perfectly!

Having the renders available makes this job much easier, and also ensures an accurate result. We have also used the files in our own models and case designs.

Downloads

The CAD files are individually zipped and will need to be unzipped, with a program like winzip or winrar, prior to use. The PDFs will open in your browser and they can then be downloaded from there.

    Great resources and I can't wait to get my hands on a micro.bit. I downloaded the CAD files but the inventor models won't open. I'm running the Student Edition of Inventor Professional 2015 with all updates in Autodesk Application Manager installed but when I try to open the assembly I get three errors like the one below.
    "Database scheme for file is (20.0 (build 200096000, 96)), which is newer than this version (19.0 SP1 (build 190203100, 2013)) of the software".
    Do I need to upgrade my version of Inventor? if so, do you know where I go to do so?

    • Hi Tim,
      These files were created in the 2016 version of Inventor by our in-house Graphic Designer. Therefore your 2015 version will not work with these files. You can get Inventor 2016 directly from Autodesk and it is free for students and educators with a 3-year licence here: http://www.autodesk.com/education/free-software/inventor-professional with a valid email address.
      Hope this helps,
      Many thanks,
      Andrew

      • We're lucky enough to be getting these micro:bits let alone have inventor 2016 on our schools computers! You should cater for all schools and get these files available on inventor 13, 14 and 15!

    I tried opening the SAT and STL files into other CAD software with with the following results:

    Solid Edge - SAT OK - STL No
    Creo 3.0 - SAT No - STL No

    Would it be possible to get the assemblies in either IGES or STEP format?

    Haas Kitroniks releasable elements to allow for easy pcb creation in some popular pcb program?

    Currently, I am evaluating easyeda but can switch to "anything" if needed.

    Is there another version of the mechanical datasheet?
    The present one does not contain the battery connector to external batteries

  • Hi,
    Thanks for this ressource. Have you got the CAD models for the servo board and the motor board?

    Many thanks
