FEATUREs
• Suitable for electrocardiography – monitoring and data collection
• Suitable for electromyography – monitoring and data collection
• Stackable shield (pass-through headers) - up to 6 shields forming 6 channels; mounted on top of each other and wired to A0-A6 analogue inputs
• Open hardware, open software project – users have access to all design documents
• Calibration signal generation by D4/D9 digital output
• Precise trimmer potentiometer for calibration (all boards are shipped completely assembled, tested and calibrated so you should not do this unless you wat to see how things work)
• Input connector for passive or active electrodes
• Works with both 3.3V and 5V Arduino boards
• Available examples for Arduino, Pinguino and Maple
