ECG1200G acquisition board is a module that converts human ECG signals into digital signals. The module uses a low-power, low-noise, 8-channel, 24-bit ADC highly integrated analog front-end, the highest sampling frequency up to 32kHz, to achieve 12-lead synchronous acquisition and transmission. The module has strong anti-interference ability, which not only realizes the accurate acquisition and conversion of ECG signals, but also has the functions of pacing detection, lead shedding detection, electrostatic protection, defibrillation protection and so on. The module can transmit ECG data to computer or other intelligent terminal through serial port for secondary development.
