Hi Core.

I’ve been looking for specific information on how to control the RF switch to use the external antenna.

I “think” one uses GPIO 21 and I have some Micropython code that appears to work using it.

However, the IO image on this page states IO41?

I did go searching through UM’s help pages but could find nothing on this.

Cheers.

Without knowing the exact boards you looked out, Im guessing they could be different “versions” and may have their own naming and order of the pin breakouts.

I can only suggest making sure you are looking at the pin out for your specific board. If your ESP32 is under the tin can, its going to get hard to know 100% what pin is coming out, if its the esposed controller you could look up the base S3 data sheet for the pin out and trace that.

UM came back to me on email sorting this so all good.

Hey there, @Mark285907,

I’m glad to hear that they got back to you.

Could you let us know what UM said? Could be helpful for a Maker down the line.

GPIO 41 controls the RF switch.

Hi Mark,

Thanks for looking into that.

I’ve also done some sleuthing and found all of the schematics for the [D] Series boards: esp32s3/series_d/schematics at main · UnexpectedMaker/esp32s3 · GitHub

I’ll update the pages with the relevant control pins.

Hhhmmm…well…..I found that schematic myself but the title block says 2022? I thought the S3[D] was relatively new?
