<img src="https://www.limpkin.fr/public/BoM/.bom_m.jpg" alt="BoM generator" style="display:table; margin:0 auto;" title="BoM generator, janv. 2014" /></p> <p>Unfortunately for Linux users, this utility is made using Visual Basic functions in an Excel file!<br />
It works fairly simply: just enter your schematics’ <strong>components references</strong> in the excel sheet, along with the <strong>corresponding Digikey webpage address</strong>. Click on the “fetch” button and the script will automatically get all your <strong>components characteristics</strong> from the internet and tell you the components costs depending on the number of prototypes you want to make. Then click the “sort BoM” button and your BoM will automatically be sorted by component type and value.<br />
Another functionality allows you to check that all the components present in your BoM are also present on the (very simple) Kicad generated one. Finally, using another Excel sheet containing your current stock, the Bill of Materials will let you know <strong>if you have enough components for the assembly stage</strong>. You can download the BoM template <a href="https://www.limpkin.fr/public/BoM/BoM_template.xlsm">here</a> and the corresponding stock file <a href="https://www.limpkin.fr/public/BoM/Stock_file.xlsm">there</a>. Here is the video of the tool in action:<br /></p>

Automatic Bill of Materials generation for Digikey components in an Excel fileurn:md5:3ff7c8e5b7cbe9503f04e3acd5699ab62012-09-02T17:22:00+01:002023-04-14T13:52:21+01:00limpkinMy Projectsbomdigikeyexcel<p>If you are ordering your projects' components on digikey... this is <strong>the</strong> script you have been missing!</p> <p>For every project I do, I like my Bill of Materials clear and simple to read :-) .<br />
However, it usually takes me quite some time to do it, so in order to overcome this I finally managed to take some of my time to create this simple script:<br /></p>
<p><a href="https://www.limpkin.fr/public/script.png" title="Script"><img src="https://www.limpkin.fr/public/.script_m.jpg" alt="Script" style="display:table; margin:0 auto;" title="Script, sept. 2012" /></a><br />
The script is still in its alpha version... but this is some of the features it has:<br />
- component count from <strong>entered references</strong><br />
- price / description / part number / manufacturer / package <strong>fetching from Digikey</strong> based on entered prototype quantity and <strong>internet link</strong><br />
- prototype price for other 100/1k/5k/10k quantities<br /></p>
<p>So you open the excel file, enter your component references and digikey links, you click this little button... and here it goes:<br /></p>
<p><a href="https://www.limpkin.fr/public/script2.png" title="Script"><img src="https://www.limpkin.fr/public/.script2_m.jpg" alt="Script" style="display:table; margin:0 auto;" title="Script, sept. 2012" /></a><br />
Pretty neat right?<br />
Ok, this is only for a windows pc... but I'm sure some of you guys will want to port it on open office ;-)<br /></p>
<p>If you want to download it.. <a href="https://www.limpkin.fr/public/BoM_template.xlsm">here it is</a> :-)</p>
<p><strong>2012/09/15 update: seems digikey changed its pages layout, so <a href="https://www.limpkin.fr/public/BoM_templatev2.xlsm">here is the adapted template</a></strong></p>
