When you design project with line connected you have to be careful about isolation. Otherwise you can say goodbye to your USB ports or even your computer!

If you use RS232 or RS485 communication you have to get one of isolated converter with USB input and yes they are not so cheap!

So i designed open hardware platform for this purpose so you can use it very easyly!

You can download BOM list/Schematic and Gerber file in below

Also you can read about test in this article (It is Turkish).

Hi,

Are you sure the isolation creepage gap is according european (or other countries) safety standards?

It seems to be quite small.
