Title: arduino nano voltage drop
Post by: nutbkb on Apr 18, 2019, 10:57 am
i have unchangeable power supply of 2-3 volt so i buy step up regulators and connect it to the power supply. set the output voltage to 9 but when i connect the regulator to arduino nano the voltage suddenly drop to 3v therefore the board couldn't work .

what is happening?
and how to fix this?

(note that the power supply is unchangeable)
