Hello, I don’t know if the post is open but I would like to know if I can remove the resistor and just solder the pads or if this resistor is necessary for the antenna. From my knowledge, a 0 ohm resistor is very important in radio frequency. Thank you for reading!

Hey sara!
Can you tell me the antenna gain(DBI) for the ESP32 Wrover E ?. Thank you 🙂

Hi.
Yes.
It’s easier to buy the ones that already come predefined to use the external antenna.

Never mind! After using high magnification, I see the resistor. Wow! This is crazy small. At my age, my hands aren’t going to be steady enough. I guess I’m forced to buy the pre-soldered ones…..

Hi Sara.

I really appreciate all of the effort you all go through to explain all of this to the community. I’m fairly new-ish to modifying boards, so I’m a little confused on what the photos are telling us. I don’t see any resistor at all, but I do see the three solder “drops” located within “boxes”. In order for the external antena to work, do I “erase” the bottom line located between the left “drop” and the bottom “drop” and then connect the line located between the top “drop” and the left “drop”? Or is there an actual set of contacts that need to be disconnected and new set connected?

Thank you in advance for your assistance.
Ron.

Hi team, great article (as always). In my case I want to install the ESP32 inside a metal cabinet and then I need the external antena otherwise I don¡t get a good WIFI connection. My problem resides in the fact that the cable of the external antena is too short, in other words I need my antena to be located outside the cabinet and therefore I need a longer cable. Can I amend the cable or is there other antenas with longer cables I could buy? (I wasn’t able to find any yet)

Many thanks in advance for any help

I have a esp32 board that has the foot print for a IPEX connector. Can anyone please tell me a part number for the connector to purchase and a supplier?

Sorry about the messed up msg – I was “saving” it as I went along and I just forgot to delete some of the earlier existing copy. It’s called “proofreading” right?
