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

Please explain what is the difference between position 1 and position 3.
Why position 1 is not recommended and position 3 is highly recommended ?

Hello, Currently we are developing ESP-WROOM-32 based board for our application. Page 15 in hardware design guidelines suggests recommended position of ESP-WROOM-32. Can someone please explain the reason behind recommended and not recommended position ? Link for the hardware design guidelines is pro...

Hello , Thanks for your prompt response. We are developing end product using ESP-WROOM-32 and I read ESP-32 hardware design guidelines as suggested by you. These guidelines are about developing ESP-32 based designs from scratch. But we are directly using ESP-WROOM-32 in our design. 1)Still are there...

Hello, We are currently developing ESP-32 based board for our application. We found two different resources namely ESP32-DevkitC-V4 and ESP32-DevkitC-V2 in link provided below. https://www.espressif.com/en/support/download/documents?keys=reference+design And we observed following differences in thes...

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.

How can I ensure to buy ESP-WROOM-32 with good quality memory chips like GD25Q32? I need good life time.

I am programming the ESP-32 with CP2102 serial programmer. Is this equivalent to writing into flash?

Hello, I would like to know lifetime expectancy of ESP-WROOM-32 Module. By lifetime expectancy I mean the amount of duration before ESP-WROOM-32 Module goes non-functional.
Please help me in this regard.
