Olimex SHIELD-EKG-EMG for Arduino

This shield is specifically engineered to capture Electrocardiography (ECG) signals, reflecting heart electrical activity, and Electromyography (EMG) signals, indicating muscle electrical activity. It converts these weak biopotential inputs into a robust analog output suitable for further digital processing by the host microcontroller's ADC.

Yes, the SHIELD-EKG-EMG is designed for broad compatibility, working seamlessly with both 3.3V and 5V Arduino-compatible boards. Its stackable header design ensures easy integration, allowing multiple shields to be connected for multi-channel biopotential signal acquisition and analysis.

The shield features stackable connectors, enabling up to six SHIELD-EKG-EMG units to be cascaded. Each stacked shield can be wired to different analog inputs (A0-A6) of the host Arduino, facilitating simultaneous capture of multiple biopotential signals from various points for comprehensive analysis.

The precise trimmer potentiometer allows for fine-tuning the analog signal output, ensuring accurate readings. Additionally, digital outputs D4/D9 can generate a calibration signal. This feature helps verify the shield's functionality and the entire signal acquisition path, ensuring system integrity before active measurements.
