Does anyone know of something I can buy that uses batteries and outputs a stable 5v DC (irrespective batter voltage being say 9v) ?
I just want something I can put batteries in and has 2 output pins 5v and Gnd - I want to use this to supply power to an STM32 board.
Searched Amazon but nothing jumped out at me!
Thx
