USB Isolator PCB
This is a very simple PCB so little documentation is needed. Information about the isolation can be found in the ADUM3160 data sheet.
It is VERY important to realise that the power needs to come from a plug pack and not the computer. Supplying power to the power input from the computer removes most of the isolation (data is still isolated).
Note that pin one is not marked on early versions of the PCB. Please refer to the photo in this repository.
PCBs are for sale on Tindie
All the USB connectors were originally purchased on ebay.
You may be able to get a sample of the ADUM3160BRWZ from Analog Devices.
Ths parts list is below, if someone can supply the part numbers for a common supplier that would be appreciated. I don't want to suggest them without ordering the actual parts and verifying fit.
