1.1.1 Ultra-Low-Power Solution ESP32 is designed for mobile, wearable electronics, and Internet-of-Things (IoT) applications. It features all the state-of-the-art characteristics of low-power chips, including fine-grained clock gating, multiple power modes, and dynamic power scaling.

I have a 22v DC power supply powering a buck converter which outputs a 5v to the board, i dont see any indications of a bad power supply. There are no loose connections, things are soldered nicely.. Just looking for ideas on how to make a reliable project with ESP32.. Thank you. Timerange: 3day. Timerange: 12hrs *edit 1: added link to code The ESP32 is a 3.3v board unlike 5v more common to Arduino boards. The board has an on-board voltage regulator for taking the 5v from USB down to 3.3v, but this is really only to power the ESP32 chip itself and not meant for peripherals.

There are relay modules whose electromagnet can be powered by 5V and with 3.3V. Both can be used with the ESP8266 – you can either use the Vin pin (that provides 5V) or the 3.3V pin. Additionally, some come with built-in optocoupler that add an extra “layer” of protection, optically isolating the ESP8266 from the relay circuit.

Jul 28, 2016 · I went even further and operate my ESPs with a 5v power supply 90% of the time. Some of them running for more than 6 month now, without any crashes. ... Still hopefully ESP32 will be 5V tolerant. You can always feed 5V to a usb plug, it must have the necessary circuitry bind it to reduce the voltage. Everything else would be ridiculous, USB IS 5V. The ESP chip itself will be fried by 5V power supply. It is controversial if the ESP can handle 5V logical input. There are contradicting statements from Espressif.

ESP8266 is a great module for IoT and DIY project specially because of it’s compact size and low-cost. However this module works at 3.3v DC, which is not as easy to find as compared to 5v DC supply. So, let’s find out how can we make a very simple 5v to 3.3v step down regulated power supply module. Quick Demo:

The ESP32 chip prefers a 5VDC power supply when running code, but 3.3VDC from a USB/serial adapter works well to load compiled code and return diagnostic information via the COMn serial port. After dropping the flash write frequency from 80 MHz to 40 MHz everything worked precisely as expected!!

Looking at the power section of the schematic I see there's a port labelled VBUS that comes from the USB connector and is connected to the USB pin on the board, so perhaps I can supply 5V on that port, however I wonder what damage that might do if I connected a live USB cable at the same time. Instead I could provide a "fake" battery voltage ... The ESP32 has an onboard 3V3 Regulator (AMS1117 3V3) which is rated at 800ma and can take up to 4.8V DC as an input, so its not safe to power the ESP32 with 9V DC battery, never exceed 5VDC if you dont want to fry the onboard Regulator. You will need to add a L7805 circuit to power your ESP32 ! 5V Regulator Circuit

Basically, I ma powering a Node 32S by its 5v pin from a 5v 10 amp power supply, and the Bluetooth wont turn on, but powering it through a USB from my computer turns it on, but powering the ESP32S through the USB port with the 5v 10 amp power supply doesn't work either.

A certified USB power supply/charger will always be 5V. The ESP32 will just draw the power that it needs. As long as the power supply can provide this power, the ESP32 will work. Again, as long as the USB power supply is certified (i.e. of decent quality), it will not damage any USB device you connect to it, including an ESP32 dev kit.

If one was to look at a ESP32 DevKit WROVER or WROOM schematic one would see that the 5V from the USB line is directly connected to the 5V of an external power supply. If something were to happen to the 5V external p/s, that something happening is directly passed onto the connected USB line. I use a powered USB hub between the computer and the ...

Mar 26, 2013 · If you have v1.0 of the board , make sure your power supply is 5V, NOT 5.1V. We have noticed a power spike in our 5.1V power supplies that can damage the IC. Long cables can also generate a large enough voltage spike to damage the IC. We recommend keeping power supply cables shorter than 6 feet to minimize potential damage. If you got a HiLetgo ESP32, you got a sheet of paper with the ESP32. On that paper you will see, on one side a few schematics. One of the schematics will be labeled power, where you will see 5V's into a regulator and 3.3V out of the regulator. In the case of a HiLetgo ESP32, I'd not supply the module with 3.3 volts.
