I need a Buck Boost converter to power my Arduino and projects so that I can use any kind of power source to run my projects.
I came across these cheap LM2577 based and XL6009 based Buck Boost converters like the ones in the picture.
However these modules have a minimum input voltage of 3v and 3.5v respectively. I want them to boost starting from 0.9v so that even a single AA battery can run my projects.
Is there anyway to modify these modules to boost from such a low voltage? maybe changing some component?
Or can you suggest me a decent Buck Boost module that takes input starting from 0.9v and has a 3A capabiltiy? I need them to be Buck Boost because I need an all in one power supply so I can also supply 19v into it sometimes or maybe even higher.
