How much voltage can ESP32 handle
The ESP32 does not tolerate voltages much greater than 3.3 V, and none of the pins from either device tolerate significant negative voltages.
How do I connect my ESP32 to my 5V
To power your ESP32 dev kit, you have three options:Via the USB port.Using unregulated voltage between 5V and 12V, connected to the 5V and GND pins. This voltage is regulated on-board.Using regulated 3.3V voltage, connected to the 3.3V and GND pins.

What is the power supply of ESP32
ESP32 Power Requirement
The ESP32 Board operates between 2.2V to 3.6V. But we supply 5V from Micro-USB port. For 3.3V there is already an LDO voltage regulator to keep the voltage steady at 3.3V. ESP32 can be powered using Micro USB port and VIN pin (External Supply Pin).

What voltage is ESP32 cam supply
3.3V
The ESP32-CAM comes with three GND pins (colored in black color) and two power pins (colored with red color): 3.3V and 5V. You can power the ESP32-CAM through the 3.3V or 5V pins. However, many people reported errors when powering the ESP32-CAM with 3.3V, so we always advise to power the ESP32-CAM through the 5V pin.
Is ESP32 5V tolerant
The ESP32's operating voltage range is 2.2 to 3.6V. Under normal operation the ESP32 Thing will power the chip at 3.3V. The I/O pins are not 5V-tolerant! If you interface the board with 5V (or higher) components, you'll need to do some level shifting.
Can I use a 5V adapter to power a 3V device
It could result in immediate failure that could result in smoke or even fire.
Can ESP32 drive 5V relay
There are relay modules whose electromagnet can be powered by 5V and with 3.3V. Both can be used with the ESP32 – you can either use the VIN pin (that provides 5V) or the 3.3V pin.
What is 5V pin in ESP32
The ESP32 LDO regulator converts the voltage from 5V to 3.3V. We can also scale down the 5V to 3.3V using an external voltage divider and an op-amp circuit. This 5V pin can also be used as a power source for external devices when the ESP32 board is USB-powered. Note: The VN pin works as both an input and output source.
What is 5V power source
5V power supplies (or 5VDC power supplies) are one of the most common power supplies in use today. In general, a 5VDC output is obtained from a 50VAC or 240VAC input using a combination of transformers, diodes and transistors.
Can I use a 5V adapter to power a 3v device
It could result in immediate failure that could result in smoke or even fire.
Is ESP32 5V or 3.3 V
The ESP32's operating voltage range is 2.2 to 3.6V. Under normal operation the ESP32 Thing will power the chip at 3.3V. The I/O pins are not 5V-tolerant! If you interface the board with 5V (or higher) components, you'll need to do some level shifting.
What voltage does ESP32 PWM output
The PWM (Pulse With Modulation) artificially creates a variable voltage between 0 and 3.3V.
Can ESP32 power 5V relay
There are relay modules whose electromagnet can be powered by 5V and with 3.3V. Both can be used with the ESP32 – you can either use the VIN pin (that provides 5V) or the 3.3V pin.
What is the 5V output of ESP32
ESP32 can't output 5V because it's powered from 3.3V, but it can take 5V as inputs and be cool about it. Therefore, in order to talk to 5V devices, I see three possible solutions: Use 5V parts that support 3.3V logic. For example, Arduino (Atmega328p) that works from 5V, still sees 3.3V as "1".
What happens if I use a 12V adapter on a 5V device
You cannot use a 12V power supply on a 5V. It will cause the device to draw more current than it is designed for and will likely burn out, causing fire hazards and explosions. In other words, if the applied voltage is more than the maximum rated voltage then the device will undoubtedly fail due to overvoltage.
What would happen if a 3V appliance used a 5V battery
The electrical appliance may get warm or overheat as 5V is more than required for it to work. The bulb will not light.
Is ESP 5V tolerant
As the ESP8266 is 5V-tolerant, […] there shouldn't be any issues, however I haven't had time to test this for longer periods of time. Therefore, if the ESP burns out after a while, just add a voltage divider or something.
Can a relay work at 5V
A 5V relay module is a single or multi-channel relay module that works with a low-level trigger voltage of 5V DC. The input voltage can be from any microcontroller or logic chip that outputs a digital signal.
Does the ESP have 5V output
Nope it goes the other way unfortunately. The ESP32 and ESP8266 are 3.3v boards. But since USB is so popular, most dev boards come with USB. USB is 5V, so that 5V pin goes through a regulator that steps the voltage down to 3.3v(one way conversion) to power the ESP32.
How do I give my 5V power supply
We need the input transformer to step down the incoming AC to our required lower level i.e., close to 5V (DC). This lower level is further used by other blocks to get the required 5V DC. A transformer is a device that is used to step up or step down the AC voltages level, keeping the input and out power the same.
What components use 5V
5 Volts is necessary for the chassis and CPU fan or USB ports. 3.3 Volts is used to power the CPU. 12 Volts can also be applied to specific “smart” chassis fans. Power supply can convert to a 100 Volt electrical current to +12V, -12V, +5V, -5V, and +3.3 V.
Can ESP8266 take 5V input
"The ESP8266 chip requires only 3.3V to communicate. The chip does not have 5V tolerant inputs. If the chip is connected to 5V devices, the chip might get damaged".
Is ESP8266 IO really 5V tolerant
Some people state that ESP8266 is tolerant of 5 V logic levels on its GPIOs, while others vehemently disagree, pointing at the datasheet-stated 3.6 V maximum.
Does ESP32 have analog output
The ESP32 DAC platform allows you to output analog voltages using the 8-bit digital-to-analog converter of the ESP32. Unlike the ESP32 LEDC Output, which can simulate an analog signal by using a fast switching frequency, the hardware DAC can output a real analog signal with no need for additional filtering.
What voltage does PWM use
The average voltage over time would be halfway between 0 and 5 V (2.5 V). PWM emits a burst of 1s and 0s whose ratio is proportional to the duty value you specify.
