# xBud

xBud is a multimodal analog front-end (AFE) for biosignal acquisition. It conditions EEG, ECG, EMG, and EOG from dry electrodes and feeds a data-acquisition device (DAQ) that digitises them, giving a complete electrode-to-data chain. xBud is DAQ-agnostic and ships tested with NI USB-600x, NI mioDAQ (USB-6451), and NI cDAQ, all supported in BXI Studio. It is built for teaching labs, biosignal and DSP coursework, and brain–computer interface prototyping.

> **Note:** xBud is for research and education. It is not a medical device and is not intended for diagnosis, treatment, or monitoring.
