Hello, I have a component that burned on my card, circled in red on the photo, can someone tell me what it is? a resistor or a diode? thank you

Looks like a T4 diode - at least on my LilyGo 868 (and 433 as well)

I hope this helps

Thanks for the information, in fact it seemed to me that the screen printing showed a diode, thanks again

I changed it with another diode but it still burns…I have another problem elsewhere I think.
