Hi, I`m creating a controller with an ESP32 DevKit V4 baseboard. The controller will be used in the industrial project. Does the internal WatchDog work well? Or is it worth using external protection? Maybe someone came across this when developing commercial projects and knows good protection options?

Hi, I need to connect an MFRC522 (RFID-Reader) to ESP32. Most contacts are busy, free contacts remain in the ADC2 section. I need to connect the SDA_SS and RST pins to any digital pins. Question, pins 2, 4, 13, 25, 26, 27 - which are included in ADC2, can normally work as digital when Wifi is on? Or...

Not entirely what you're looking for, but perhaps this helps: The dimensions of the board itself are documented here, and the headers are standard 2.54mm headers.

That's exactly that)

Thank you!

WiFive, Thank you!!!!!

Hi, In my project, there is an ordinary ESP32 DevKit, it is in a metal construction and there is no way to bring it out, I understand that ESP in a metal box is not good. Are there any ready boards (where there is USB and other components) with an ESP32-WROOM-32U, to which I could connect an externa...

Hi, I have ESP32-DevKit board. Which core control the wifi connection? I create a sketch with a flashing LED and connect to the Wifi network. When I turned off the Wi-Fi router, I noticed a failure in the blinking of the LED. As soon as the ESP connects to the network, the blinks are restored. In th...

Hi! I need to control the stability of the Wifi connection and reset the Wifi driver mode in case of problems with reconnection. In the documentation, I found a way to completely stop Wifi: esp_wifi_disconnect (); esp_wifi_stop (); esp_wifi_deinit (); This should completely disable Wifi and clear it...
