can some one tell me the max voltage of a esp32 input pin can take i have a lot of sensors that give out 5v logic high and dont wont to overload the esp32 ????? also am i right in that esp32 pins gpio are input
0x32, /*MaxPower 100 mA: this current is used for detecting Vbus*/ 0x00, /*bInterfaceSubClass : 1=BOOT, 0=no boot*/ 0x00, /*nInterfaceProtocol : 0=none, 1=keyboard, 2=mouse*/ 0x32表示为该口提供的最大输出电流。(0x32换算十进制即50,再×2 即100)即这里提供最大100ma输出电流。USB...
Hi, can anyone tell me the absolute maximum input voltage of the ESP32 ADC pins? I've seen a few blog posts suggesting 4.0 volts but I can't see that any any Espressif docs. Also, does that change with the ADC attenuation setting? Thanks!
Accurate reading of the sensor voltage is absolutely crucial. Should I use extrenal ADC such as ADS1115 for accurate readings? Thank you for your suggestions. Br 1 post • Page1of1 Return to “ESP32 Arduino” Jump to Who is online ...

Can I connect a voltage greater than VCC to a input pin? For example my ESP32 is running at 3.3V and I am putting 4.2V into the IO input it. Right now, its reading the logic value correctly, but I don't know if is going to cause a problem over a long time. ...
