I suspect I have been searching using the wrong term but can't for the life of me find a solution to this.
I was hoping to find a little board which I could use to power my ESP 12F from a regular usb phone charger. Essentially a micro USB port power input and stable 3.3v output that I can connect to my ESP. Does anyone know if such a thing exists? I have seen these

Which I guess I could somehow wire to a micro USB connector but thought this would be a common requirement and would rather buy a ready made board.
There are these serial devices but from my experience the power output is not very ESP friendly and causes instability issues (at lease FTDI one i have seems to).
Anyone have any thoughts?
thanks in advance
