Thank you for the answer.I don't want to use an RF module in my setup. I want to use the following setup:
- Arduino controller board (CE certified)
- EMG sensor (CE certified)
- Vibrating motor (CE certified)
I can use them separately and simply connect them together with connectors, or I can put them all together in a box.
Have I to selfcertify this system in this case?
Yes, in theory at least, since its the finished article that needs to be certified, not the component parts.
