The Bridge allows you to connect to your Ruida controller using your normal WIFI network. It’s also smarter than those AP mode connectors, because it’s specifically designed for this.
Ruida controllers use UDP messages, which are not guaranteed to be delivered, and the Ruida controller doesn’t provide a retry mechanism, so if a packet gets dropped due to interference, the job fails.
The LightBurn Bridge communicates with the laser using a network cable, so no interference is possible, and it talks to the host PC with TCP/IP, which does guarantee delivery, and automatically handles re-sending packets if something drops or gets corrupted.
I would be very surprised if the device you show above does anything like this.
