kaanpars/16_channels_eeg_card
I designed cards both in INA333 + TLV4333 and ADS1299. It is up to you which analog or digital output you should want to get. Importing restrictions in Turkey dragged me to designing my own sensor cards. ENJOY!
It measures 35 × 23 mm and has 2 copper layers, 1.6 mm thick.
24 parts, built around the ATTINY13A-SSU, INA333AIDGKR and AO3400A. 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.
From the dylancvdean/thinkingcapHW repository on GitHub, at the commit this page was made from: the board is Hat PCB.kicad_pcb and its schematic Hat PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask dylancvdean before reusing the design.
