When connecting WIFI

Happens on Esp32

About “Brown out detector was triggered”

Of the following 6 points

Which is the main cause?

Healed while improving the following six.

Is there anything else?

Question intent

When making a board

I want to use it as a reference for stable operation.

1, noise

Example: IC GND, where multiple wires should be wired, must be disconnected

  1. I connected FAN etc. to the output. As a result, the current of the serial power supply became insufficient. It was over 260mA.

  2. Because of the hand-assembled experiment, the ESP32 IC was supported by electric wires.

It was supposed to stand up vertically.

4, power supply plus GND wire is too thin, all examples

I have wired with multiple cores.

  1. Pull up GPIO35-39, which is not internally pulled up, with a 10K resistor.

  2. WIFI connection control series

It will be completed in 500ms

I tried to perform extremely short processing by hand in an environment vulnerable to noise.

Sounds like your power supply isn’t capable of providing enough current to your motors.

In other words, I would like to know the following.

Current

While observing the above items

As shown in the attached figure, it has been in operation for more than 10 days, but it is operating normally.

Is there any problem with the drawing of the following url for stable operation for a long period of time?
