There are different types of ESP32 development kits available but the function of GPIO pins remains the same across all development boards. You can define the pins the same way in firmware also. The following picture shows the pinout diagram of the ESP32 DEVKIT V1 DOIT board. In your versio...

Just to make sure, can you use an oscilloscope or logic analyzer to see if there's actually any activity on those pins? If they are attached, you should see all kinds of signals when the ESP32 is booting up. Glen104TMR Posts:6 ...

Re: ESP32 VIN pin as 5V outputby Agree007 » Wed Aug 14, 2019 4:53 pm Suggest you find the circuit diagram for you board, it will show how the 5V pin are conneted to the usb input or you can try messure the resistens between the 5V pin and usb 5V in with an ohm meter. ...
if PSRAM is to be used. The standard example ESP32 cam project does use PSRAM, as the camera code needs to assign large buffers in memory to process the incoming frame information. RandomNerdTutorials does have an example of using a PIR sensor with an ESP32Cam board, which uses GPIO13....

Is it on the rising edge of the EN pin? Maybe a better question is... Can anyone provide a timing diagram for the strapping pins? To include the set up and hold times for the strapping bits and EN pin? I'm building a new board and want to allow setting the strapping bits dynamical...
