The Serqet family of projects are designed to isolate your host and slave devices. The Serqet_FS_U is a low speed (1.5Mbps) and full speed (12Mbps) USB isolator based on the Analog Devices ADuM3160 USB isolator and optional Recom Power R1SE-0505-R isolated DC-Dc convertor.

The board features two jumpers which have to be set to the same speed, either LS or FS, before plugging it in. It’s designed to fit in the Hammond 1551S housing.
