This paper introduces a portable multi-functional biopotential signal acquisition device. Through simple set and electrode selection, the device can collect, display and store EEG and ECG data in real-time. It has high precision, small size and low power consumption. The lower computer consists of ST STM32 microcontroller STM32F103 and TI ADS1298 analog front-end IC,and it saves a number of peripheral circuits. Lower computer transmits the data to host computer through USB2.0 protocol. USB driver of the host computer is realized by NI-VISA,and the software is designed by LabVIEW.
