Wires are unshielded, which leaves this succeptible to interference from power line hum. Perhaps this would be suitable for an EKG or EMG, but not EEG.
Cable plugs into board and the snap on pickups attach well. I get good A to D results .
This cable is perfect to be used for all Biosignals and with different boards
Recebi o material na data prevista e o mesmo é de boa qualidade
Using these with an M0 datalogger and a matching MX30003 board to build a 24+ hour portable ECG monitor. The 500 MAH Lithium battery that Sparkfun sells powers it for about 30 hours. Very satisfied!
These don't seem to work well at all for capturing the EMG signal using the Myowear shield, I've tried every muscle and both the color arrangements and nothing works.
Sorry to hear that the leads are not working well. Consider filling out a return ticket and we can look into your case: https://www.sparkfun.com/returns
