AD7173 IC and related component placement and routing

tharaka27 commented 5 years ago

Hey, a little questions.. why are you guys using AD7173 IC rather than ADS1299 ?

CloudyPadmal commented 5 years ago

Hi, There are quiet a few reasons;

  1. Price (AD7173 < $17 | ADS1299 < $30) There is an alternative suggested in #55 for AD7173 replacing it with an IC of similar specs
  2. Dimensions (though it could be tolerable)
  3. NeuroLab is targeted for hobbyists. So we don't require medical grade quality readings.
