Where did the photo come from ?
Chances are the USB port supports either a serial channel, or there’s a program that supports the control of the sign.
Without more information, it’s hard to guess.
If it’s plugged into your PC, what does Device Manager say when the port is connected?
Use your smart phone, and the relevant app, as shown in the video.
It doesn't show up on my Bluetooth settings or wifi settings.
and even i don't have any details on it. its chip is a Prolific 2303 hxd
