For some areas like medical equipment or test equipment it is required to galvanically insolate the peripheral from the PC. This little device serves this purpose.

It can be jumpered for USB powered or externally powered. The mini USB port serves as a power connector. A cellphone AC adapter can be used as long as it is isolated. In order to insolate the USB power the Traco DC/DC converter is used.
