Learn MoreYou can supply power to the Arduino Uno using an AC-to-DC adapter connected via the board''s power jack. This jack is typically fitted with a 2.1mm center-positive plug. Another alternative is using a battery, and in cases such as this, it …
Learn MoreI''m using a 12V adapter and a 2S 7.4V Li-ion battery to power my electronics, and I would also like to power my MCU with it. To switch between the adapter and battery I''m using a BQ24133 from TI. I $begingroup$ I don''t have a thought that''s full-fledged enough to be a standalone answer, but I''m surprised none of the good existing …
Learn MoreAs long as the microcontroller on the board, the LEDs, or any other peripherals, draw current, the linear regulator wastes power equal to difference between supply and board voltage x current drawn. So, a first fix would be to disconnect the power indicator LED on the board, and not use any of the other LEDs as far as possible.
