adambrum commented 7 years ago

been looking at the Adum4160 usb isolator, might be easier than usb-serial-isolation.

Could this be a solution ?

Several board are available based on that chip. Typical price about $15 or £30 or more. Example https://www.digikey.co.uk/product-detail/en/adafruit-industries-llc/2107/1528-1784-ND/6238004

Doubtful a board based on it could be made any cheaper. If sold in quantity it would need to meet EMI regulations.
