Minimal DIY power supply for ESP?
Posted: Thu Feb 26, 2015 9:23 pmI have very small space inside some device for adding ESP-01. Since only AC 100V is available there, i will obviously need 3.3V power suply of some sort. Does anyone have smart ideas about the schematics of the simplest possible 3.3V power supply with minimal number of components with just enough wattage to power ESP? I hugely appreciate your brainstorming on the subject!
