So I recently bought a ESP8266 chip, it requires 3V3 and a large current( around 210mA max which is more than that can be supplied by an arduino uno at least). I managed to connect it to my arduino uno and got it to operate in standby mode, but Wifi mode wouldn't work because it requires more power.
After reading multiple online articles, I've decided to construct my own power supply. I'm planning on hooking 3 AAA batteries in series(4V5) and then use resistors(of small values to decrease power loss) to construct a voltage divide which powers the chip.
My concern is that I have not seen a single person doing this online and this seems like a straight forward thing to do, which makes me worried. Did I miss something? Is my plan feasible?
