Pi Zero W rev 1.1 - no WiFi module detected


I recently went back to a Pi Zero W I got in 2017 from Pimoroni and flashed a new Raspbian Buster Lite image. The issue is there is no WiFi module detected.

raspi-config shows “No wireless interfaces found”, and ifconfig etc. don’t show a wlan0.

I’ve also tried with the full Buster desktop, but that has the same issue. I tried with stretch as well, but that didn’t help.

I have the wpa_supplicant.conf in the right format but that doesn’t help either.

WiFi was definitely working before, so I am hoping someone can please help me in working out if the WiFi is dead or not.
