I want to connect external device such as ECG sensor to muse port.
Is there any external input port in muse ?
The official accessories aren’t yet available but you can strip a plain old usb micro cable and connect D- (pin 2) to a chest electrode for a strong ecg signal. Preset 13 gives the extra channels. The “research” firmware is not released and unavailable for now but when it is it will allow for all channels to be streamed concurrently.
