I found this one: https://www.instructables.com/PCB-Business-Card-With-NFC/ Looks closer to yours? Not sure how you did the 24k gold part tho ;)

Yes, that’s the one I used afaik. The gold is one of the materials you can choose to plate your copper on the board at manufacturing. “Enig”. Increases conductivity but also looks sexy :D I think every board was $8 on MOQ.
