I am using a esp32-c6 board to control some servo motors.
It is powered through the 5V and GND pins. There is a green led blinking apart from the controllable neopixel led.
This power led is continuously blinking.
How can I stop it ?
just desolder it...
Why did you placed your question in the "Opta" category?

oops I really didn't notice the subcategory. I wanted to select "hardware"
isn'T there any generic hardware category ? or specific esp32 ?
Esp32 is not an "official" Arduino hardware. So you need a something in the "Other Hardware" tree
It should be constant on not blinking. There may be a problem with your board or wiring.
I tried many esp32-c6 boards (actually lately what I used are esp32-c6 zero boards from waveshare) , all have blinking green led. And everything is working (except that I can't turn off the led)
how can I move this thread/question to the "other hardware" tree ?
This one does not blink
Maybe you should post the datasheet for the C6 you actually have.
What you think is the power LED may be something else
it is this one:
datasheet:
Odd..
According to the schematic it only has the RGB LED and no power LED.

I'm sorry ; correct board is here:

There is no datasheet that I could find for this one.
there are 2 leds
I can control the neopixel led
now the neopixel led is set to orange and solid, and the other led is blinking green.
Are you sure this time!
yes this time I'm sure this time.
In fact it is surprising that the other board does not have power led. I also used it previously and I believe it also had some sort of power indicator (not sure though)
I think the LED is connected to GPIO15. So if you are using that pin for SPI, I2C, or UART it will cause the LED to blink.
There seems to be another LED that indicates charging. That may be the one that is blinking.
Here is the schematic
I'm not using GPIO15
Only using 3 pins:
18 and 19 for 2 servo motors
8 for the onboard neopixel led
Are you sure that the power led is connected to GPIO15 ?
if so, how can I turn it off ?
There is no power LED. One LED is connected to GPIO15, the other LED is connected to the battery charger IC, I think that is the one that is blinking.
It's the one on the right side marked BAT
ok, so it's not controllable ?
is there a battery charger circuit on this board ?
If your board has the battery LED, then yes it does have a charger.
so there's no way to control this led ?
