An USB isolator acts as being a barrier, preventing any immediate electrical relationship amongst your Personal computer and the isolated device.
The purpose is to attach two HydraUSB3 V1 boards with each other (one in addition to One more) for multi CPU communication / special streaming capabilities and also to use the different supported protocols among two boards (one board can act as product and one other as host with the help of PB24 jumper to identify host or product…).
For data we may also connect with ESP32 for the duration of bridge mode by connecting a 2nd MicroUSB connector on HydraBus so that you can have an other terminal to communicate with ESP32 I/O for instance to established EN pin to +three.
