Hi guys, How do I drop the voltage 5v to 3.3v for ESP32. Please can I get easy and better idea?
Signal or power?
Welcome to the forum
Which voltage do you want to drop ?
Where does this voltage come from ?
Better than what ?
For detecting digital signals where you need just the voltage and a minimal current of 0,5mA a voltage-divider is sufficient.
For powering anything even a super-low-current sensor a voltage-diver is unsuitable
This requires a voltage-regulator
either a linear one like L78 3.3
or a really small DC-DC stepdown-converter
Depending on how much current you need it must be a medium size DC-DC-converter
an ESP32 should be supplied with a power-supply that is able to at least 300 mA because WiFi sending causes high current-spikes much higher than the average 50mA an ESP32 draws
best regards Stefan
Thank you Stefan
