Re: Power pins of ESP-WROOM-32 showing connectivity

Sorry for my late response.

I am controlling vibration motors with my ESP-32 Module. ESP-WROOM-32 module transmits the signal to n-channel MOSFET to tuen on vibtation Motor.

Voltage Supplied to motor : 8 V
Voltage supplied to ESP-32 is 3.3 V

Power pins of ESP-WROOM-32 showing connectivity

Hello,
I designed an embedded application based on ESP-WROOM-32 module to give strong vibration alerts. Initially it was working well. Suddenly it stopped working and the power pins of ESP32 (3V3 and Gnd pins) showing connectivity.

What might be the reason for this? Please help me in this regard.
