Click For Summary
The ESP8266 WiFi module can be powered directly from a computer's USB port without risk of overloading, thanks to its onboard 5V-3.3V converter. Users can also connect an external 5V power source, but it's unclear if both power sources can be used simultaneously. A high-resolution photo of the board's opposite side could provide further insight into acceptable connection options. The discussion emphasizes the importance of understanding the module's power specifications to ensure safe operation. Overall, the board is designed for flexible power input, making it user-friendly.

Hey guys, quick question on this module.The manual states
" 5V-3.3 converter onboard for operation from USB"

Does this mean that i can power the board straight from my computer without error from "overloading" the board.i ask this because a lot of other modules such as these don't work like this.

cheers

Do you have a link to the exact board you are using?

You can power it from either an external 5V source or the USB connection. The onboard regulator and circuit will determine the exact details of the range of voltages that are acceptable.

You may or may not be permitted to run both the external 5V power and the USB at the same time. Can you post a high resolution photo of the side of the board opposite the wifi module? We may be able to give you an idea of more of the acceptable connection options.

The website only has the module side. If we could see the other side it might help to get better answers.

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
