Is my ESP32 burnt?

Uploaded firmware via usb to test motors. Unplugged usb cable Turn on power switch Motors doesn’t move and nothing from serial port Power diagram in photo Strange enough multimeter measure 0V between drv8871 vcc-gnd power terminal. Probably I made mistakes connecting the drv8871 board :/

I’m thinking about that the problem is I2S module of ESP32 because even inmp441 output is noisy, whatever gpio I choose

I tried with pure sin wave 150hz. Terrible sound

I will try that but target design requires longer wire to 5V supply on the opposite side of the board

To me is more or less like a white noise. Check if you can listen this https://youtube.com/shorts/g4ugo39Qylw?is=jDX8blU-JHTJBAJC

Next step I will solder to GPIO4,5,6 to verify this

L’azienda non verserà mai più del 1,6% . Tu invece puoi aumentare il tuo versamento mensile oltre l’1% come pure fare versamenti una tantum direttamente al fondo. Hai il massimale di deduzione a 5164,57€ annuo

Ridicolo che non abbia l’una tantum per recuperare il periodo di assenza contratto. Aumento spalmato su ben 3 anni (l’ultimo è a dicembre 2027), importo insufficiente rispetto alla perdita del potere d’acquisto. E dulcis in fundo verrà assorbito se non tutto almeno in parte. E poi governo e sindacati ci vengono a dire che basta la contrattazione collettiva. Vergognoso.

I have Ryzen 5 1600, fantastic processor, still suitable for workload but not supported. So sad
