John if you like I began a BOM. Made it easier for me to gather the parts pre construction. Also I made a detail of the edge connector fingers to the PCB solder pads pre soldering. Do you have a source repository for the extender? I could branch it and send a pull request. I'll add more detail to the BOM if you like I could add the Digi-Key part numbers that you have in the article detail. Don't know where and what size Google puts this image. Let me know if you want the original 4020x628
Thanks for publishing the extender.
