I must've put those values in there when working on it initially, expecting to fill them in later (since they are appropriate value for the adj. pot.) and never went back, nor verified before I assembled the board. They should be MUCH lower. I also completely missed the needed resistor before the pot. to reduce the voltage going into VRef. Thank you so much! | |
