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

Lee.

For this particular scenario I need it to be connected with a wire (usb ideally) as the device needs to be away from the plug socket.

Wouldn't it be easier and cheaper to just use a WeMos instead?

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
