Beware of Pseudo Open Source Hardware EKG/EMG fakes of our shields by Duinopeak company

We got support question for Arduino EKG/EMG shields which do not work correctly.

We did the initial questions to make sure they use correct drivers and software, and it seems the customer did everything correctly but couldn’t get correct signals but only noise. Then we asked him to send us picture of how he is connecting the boards.

To our surprise we got picture with blue mask boards. All our EKG/EMG boards are with red mask, so we found these guys easily. All their contribution back was to remove Olimex from the silkscreen and to put their name on the boards, although they keep the OSHW logo they didn’t put their CAD files available for download, which is not great loss as they didn’t contribute at all except to change text on the boards.

On top of this probably they didn’t even test the boards as the one in this particular customers didn’t work.

What is most annoying is that they link all our files to their web page, so mislead people that they buy our boards.
