3. Finally, I am using a voltage divider configuration (2 100k resistors) in order to monitor my battery and USB input (I can determine whether battery or usb is plugged in).
Hi Stowhite,The reference is 3.3V. Is is tied to the input of the mcu.Hi TomGeorge,I am using the AP2112k-3.3 . I agree. I do not think the output of the buck regulator will be enough. Do you think I can just use the buck regulator then?
