EEGFrontier
EEGFrontier is an open-source EEG device designed to measure focus and attention during study using real brain signals. It uses a custom-built PCB with a professional EEG analog front-end to capture raw EEG data and stream it in real time to a computer via USB.

Updated Docs + Added imagens, released build firmware
I have updated de docs, created one more imagens showing how put the electrodes:
I have created a software with desktop and web to read and organize signals, it's optional for this board, idealy is build our own for our use, but I created one:

Finished Repo Structure
Have organized everthing to submit review, and created pcb/, sch/, ready for submit :) Added some drl and gerbers files for JLCPBB:
Take a look at bom/, will have everthing you need!(i guess/expect)

Were we go, created a simple diagram and a lot more
Created an Diagram for easy understanding:
Created github repo with README, pcb and firmware, created a tag with firmware.bin!
I have modificate the header to use the Molex header from Mouser BR:
Searched prices and created a BOM + Prices, a little expensive 😔
Estimated Total
Total: $274,46

Routed PCB + Added GND Planes and Some Draws
Mewtwo are reading your mind...
Routed that PCB, added GND Planes for every Layer, add personalized:
I have to do a plan/diagram explaning, how it will works
See that GPIO with noting? I has thinking about add some thing like more leds ou stuff like that:

Created Schematic
I have spend some time studying how to create that, choosed 4 channel to our EEG, created Schematic :)
I'm glad to make that's projects, I have something to do
