I'm visiting a friend in Shenzhen for a week, and I thought I'd browse around the electronics market area. I found countless shops and buildings with consumer electronics, ICs, phone/watch accesories and parts, security products, LEDs, and other things. The scale of the place is amazing!
However, so far I didn't encounter any area or store that had prototyping tools/supplies or test equipment (e.g. scopes, VNAs, etc.).
It's my first time to visit so I may have a lot of misconceptions.
The closest I found were shops that specialized in electronics repair tools (soldering/hot air stations, inspection scopes/cameras, and handheld DMMs). I also saw a few small sales counters with things relating to single board computer platforms.
Any suggestions for test equipment? There are too many buildings to explore casually in my available time. Maybe this kind of thing is generally online order only.
