Relative newbie here, so forgive any obvious mistakes. I'm trying to power my ESP01 chip (3.3V input, up to 300mA current draw), and I'm considering using AA batteries for the power supply. Can the chip handle a 3V input only using 2 batteries, or should i use 3 or 4 batteries to have 4.5V/6V input. If so, can you recommend any regulators to step down to 3.3v and >300mA?
Essentially, I'm trying to minimize the number of components and the cost.
