Yes, an ESP might run on 5V but yes, it will eventually self destruct because of it.
Yes, you might want to ignore some antenna recommendations in a development phase but yes, it will eventually hit you in the face when production has already started.
Maybe a small primer on antenna design might give you some insight on why antennas are designed the way they are.
If you have the possibility, you could also opt for an ESP-07S, which is identical to the ESP-12, with the difference that it has a connector for an external antenna.
Hi, I'm not doubting the manufacturer. I'm sure he's correct and I should follow the guidelines, just like everything else we do.
But in my case I have little space and I can not follow what they recommend.
But since I've never done anything without following this rule, I'm not sure what effects they'll have ... If I'm going to lose a lot of wifi or just dim the signal a bit. for example.
Thanks for the tips and willingness to help me!
I really liked the link on the antennas, I'll read it more calmly to understand it well.
As for the ESP-07S does not have 4M flash. And the case of the board does not have space for an external antenna.
But it was a great idea!
It will probably serve me here on another project.
TKS for you help!
