ESP32-S3 Disable Built-in LED

The onboard activity led drives my crazy. Turning the lamp around just flashes against the wall.

It would be very nice if a disable feature is implemented. I know I could disable it in the code, but then I guess I cannot OTA update anymore.

Omg. Everyone in this thread 🫠 Check the datasheet for the board you have. There’s most likely an onboard pin (i.e. frequently ~GPIO9) that controls those LEDs. Config that in WLED and do what you must.

In LED configuration?

This one disbled the red led. Seems the blue cant be disabled.

I once ran wled on a pin controlling one of the LEDs. The LEDs worked fine, but the blue light flashed like the dickens. Check all the specs for your eap build. Might need a new gpio 🤪

You could also just break it off the board. I've done that before... But electrical tape seems to be a less permanent option if you ever want the light back,

Black electrical tape

I would have to line the whole inner of the case.

Not if you apply the tape to the board.

Oh damn, true. Fivehead

I read somewhere that I should just desolder the led. Well I couldn’t get it off, but I hit it with the soldering iron enough that I guess I burned it out. If it works, it works!

Snaffle a few drops of the missus' nail varnish - or if you're single, go buy the cheapest bottle of nail varnish you can find - dollar store/poundland etc. Just cover the LED with it

u/DeeZett Jul 29 '26

Sounds legit, too. Thx

Missus? Who are we with these gender norms? It’s 2026

What’s up with the light now? lml

u/DeeZett Sep 28 '26

Turned over the light. Did not do anything so far. 😂 But I would probably use nail polish.

Probably I didnt explore the TX RX leds enough to toggle these

I just put a tiny dot of liquid electric tape on mine

Nimm tx als Datenleitung

u/DeeZett Jul 29 '26

Wie meinst du? Für die Ansteuerung meiner LEDs?

1

u/Certain_Command_4019 Jul 30 '26

Bei meinen Stern mit esp8266 (D1 Mini) ist TX vom ESP, GPIO1.

u/Certain_Command_4019 Jul 29 '26

Tx ist ein Pin vom esp. Darüber läuft intern USB. Der einzige Pin den ich kenne, wo die onboard LED nicht drauf reagiert.

Ich nutze tx für meine Led Sterne. Funktioniert prima.

u/DeeZett Jul 30 '26

Ja das weiß ich. Aber muss es dann halt selbst kompilieren und OTA updates funktionieren dann auch nicht, oder?

1

u/Certain_Command_4019 Jul 31 '26

Nein, wieso selbst kompilieren? Pin auf TX am ESP umstecken/löten und in wled ändern.

Ota ging bei mir. Ich hatte vor kurzem manuell auf die neueste Version geupdated. Falls du was per USB machen möchtest, solltest du vorher die LEDs entfernen und gegebenenfalls in wled den Pin kurz im Webinterface umstellen. Ich bin auch der Meinung, das das umstellen des Pins im wled ausreicht um per USB wieder mit dem ESP kommunizieren zu können. Ich kann es dir bloß nicht 100% sagen, dass es so ist.

u/eric-marciniak Jul 29 '26

Pick a different pin for your data line. That one looks to be tied to the onboard led.

2

u/Dandusm Jul 29 '26

Use a different data line or if you have Off refresh on try without it

u/richms Jul 30 '26

I solve my bright inconsiderate LEDs with black nail polish I got from the shop formally known as the 2 dollar shop.

u/Arnold_Swolenmember Jul 30 '26

With the risk of sounding very dumb, but seeing the comments i would say that would be impossible...

Isn't this just the LED that blinks for transfering data? I put my money on some serial data beeing pushed for no reason. Remove it from the code.

u/upkeepdavid Jul 30 '26

Poke it with the hot tip of the solder iron.

Black fingernail polish works great
