FreeBCI WiFi-II EEG Acquisition Module ADS1299 ESP32 HDMI-compatible 16-Channel EEG Acquisition with Connection Cable

FreeBCI WiFi-II EEG Acquisition Module ADS1299 ESP32 HDMI-compatible 16-Channel EEG Acquisition with Connection Cable

Description:
- EEG acquisition module, WiFi+USB wired version, using HDMI-compatible interface to connect lead wires, convenient for connecting integrated gold cup electrode harness and EEG cap.
- Supports both WiFi and USB signal transmission methods. The USB interface can be used for both charging and data transmission. However, since the USB charging interface is not isolated, please do not acquisite EEG signals while charging.
- Using a single-chip ESP32S3 for control and WiFi/USB wired transmission, without an external MCU, compared to the MCU+WiFi module solution, it has lower power consumption, better performance, and can achieve high-speed sampling. WiFi supports both AP and STA modes, and can function as a hotspot or join a WiFi network. The working mode can be configured through the built-in Web Server on the data acquisition board.
- Supports multiple sampling rates such as 250, 500, 1000, 2000, 4000, etc. It supports up to 4000Hz synchronous sampling in 8 channels and up to 2000Hz synchronous sampling in 16 channels.
- Built-in 2000mAH lithium battery with a battery life of over 8 hours.
- Providing self-developed upper computer executable programs for Python to achieve various functions such as waveform display, real-time FFT spectrum, band calculation, brain topography map, data file storage, and real-time forwarding of LSL network data streams.
- Support hardware working mode configuration, can support differential, SRB1 common reference, SRB2 common reference, BIAS common mode negative feedback output and other functions.
- EEG data can be forwarded in real-time through LSL and imported into EEGLab for convenient subsequent processing.
- Onboard TF card slot, which can be detached from the upper computer for storing EEG through button operation.
- Providing USB communication protocol and support secondary development under USB communication mode.
