ADS1299 EEG Headset 🧠

This is a DIY / custom electroencephalogram reading device which is connected eeg electrodes that can connect to brain at designated areas.

It reads brain wave signals and digitizes them into the computer which is called brain-computer interface.

Why am i doing this

I have a larger project and i want to join the competition with my pcb.

Questions

How big is the PCB Design PCB?

It measures 113 × 110.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the PCB Design use?

100 parts, built around the AMS1117-3.3 and IRLML6402. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the PCB Design KiCad files?

From the MohamedAlDeep/EEG-Headset repository on GitHub, at the commit this page was made from: the board is PCB/PCB_Design.kicad_pcb and its schematic PCB/PCB_Design.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the PCB Design design in my own project?

Its repository states no licence, so its author keeps all rights: ask MohamedAlDeep before reusing the design.
