The article has some mistakes, namely, this isn’t the WiFi / WLAN, it is a USB port and card reader slot PCB. I came to iFixIt to double-check the part to upgrade to WiFi 6 (ax). Once you fix the part name, the article is good! The part number DA0BUITH8D0 is what to search for when trying to buy one. I didn’t need one, but looked it up just the same, there are not a ton of these out there and I would probably just resort to a USB reader.
