kicost 0.1.36

Build cost spreadsheet for a KiCad project.

KiCost is intended to be run as a script for generating part-cost spreadsheets for circuit boards developed with KiCad.


  • Processes the BOM XML file from your KiCad schematic to create a part-cost spreadsheet by scraping the web sites of several popular distributors for price and inventory data. (You can also enter your own quantity-adjusted pricing data for specialized parts or those not found at the supported distributors.)
  • The spreadsheet contains quantity-adjusted pricing from each distributor for individual parts and the total board.
  • Enter the number of boards to be built in a spreadsheet cell and all the pricing for the total board and individual parts is updated.
  • The spreadsheet also shows the current inventory on-hand for each part at each distributor.
  • Enter the quantity of each part that you want to purchase from each distributor and lists of part numbers and quantities will appear in formats that you can cut-and-paste directly into the website ordering page of each distributor.


0.1.36 (2017-08-14)

  • Parts may now be assigned to a variant by giving them a variant field.
  • Parts may now be assigned to multiple variants.
  • Parts may be designated as “do not populate” by giving them a DNP field.
  • DNP parts or parts not in the current variant will not appear in the cost spreadsheet.

  • Fixed crash caused by uninitialized array in Digikey webscraping module.
  • Place any available scraped part info into spreadsheet even if part is not available from a distributor.

0.1.27 (2016-07-26)

  • Fixed scraping of Digi-Key pages to correctly extract available quantity of parts.

0.1.26 (2016-07-25)

  • Progress bar is explicitly deleted to prevent an error from occurring when the program terminates.

0.1.25 (2016-06-12)

  • Contents of “Desc” field in component/library were being ignored when generating spreadsheet.

0.1.24 (2016-05-28)

  • Fixed part scraping from Newark website.

0.1.23 (2016-04-12)

  • Added progress bar.
  • Added quiet option to suppress warning messages.
  • ‘manf#’ and ‘manf’ fields are now both propagated to similar parts.

0.1.22 (2016-04-08)

  • Extra part data can now be shown in the global data section of the spreadsheet by using the new --fields command-line option. This commit implements issue #8.

0.1.21 (2016-03-20)

  • Parts with valid Digi-Key web pages were not appearing in the spreadsheet because they had strange quantity listings (e.g., input fields or ‘call for quantities’. This commit fixes #36.

0.1.20 (2016-03-20)

  • Prices of $0.00 were appearing in the spreadsheet for parts that were listed but not stocked. Parts having no pricing list no longer list a price in the sheet.
  • Parts with short manf. numbers (e.g. 5010) were not found correctly in the distributor websites. The manufacturer name was added to the search string to increase the probability of the search finding the correct part.

0.1.19 (2016-02-12)

  • Local parts weren’t showing up in spreadsheet because of previous fix to omit parts that had no quantity field (non-stocked; not even 0). Fixed.

0.1.18 (2016-02-10)

  • Made change to adapt to change in Digi-Key’s part quantity field of their webpages.
  • Omit parts from the spreadsheet that are listed but not stocked at a distributor.

  • Fixed exception caused when indexing with ‘manf#’ on components that didn’t have that field defined.
  • Replaced custom debug_print() with logging module.

0.1.14 (2015-12-31)

  • When scraping a Digi-Key product list page, use both the manfufacturer’s AND Digi-Key’s number to select the closest match to the part number.

0.1.13 (2015-12-29)

  • ‘kicost:’ can be prepended to schematic field labels to distinguish them from other app fields.
  • Custom prices and documentation links can now be added to parts in the schematic.
  • Web-scraping for part data is sped up using parallel processes.

0.1.12 (2015-12-03)
