About

The OpenBCI Ultracortex Mark IV is a fully open-source, 3D-printable EEG headset supporting up to 16 channels via the Cyton + Daisy biosensing boards. Designed for the research, maker, and developer community, all hardware files and firmware are released on GitHub under open-source licenses. Uses spring-loaded dry electrode nodes repositionable to any 10-20 system location. The OpenBCI GUI provides real-time visualization with plugins for BrainFlow, Lab Streaming Layer (LSL), and Python. The de facto standard for open-source BCI development, used in hundreds of university labs worldwide.
