The Heart BioAmp Candy is a purpose-built ECG sensor module that simplifies the acquisition of electrocardiogram signals. It integrates a high-precision instrumentation amplifier with a fixed gain of x2157 and a dedicated bandpass filter (0.5-34 Hz) to isolate the cardiac frequency band, effectively suppressing baseline wander and high-frequency noise. This design ensures stable, readable waveforms suitable for heart rate variability analysis, basic arrhythmia detection, and physiological education.
Constructed as open-source hardware, the module provides full schematic and layout access, empowering researchers, students, and makers to modify or integrate the circuit into custom biomedical devices. Its three-electrode configuration (Positive, Negative, Reference) follows standard clinical lead placements, and the wide 3.3V-5V supply range guarantees compatibility with a vast ecosystem of ADC-based microcontrollers and single-board computers without requiring additional signal conditioning.
