Re: ESP32S not returning frame buffer pointer in ESP32-CAM clone

Found the root cause of the problem - my PCB had incorrect C13 capacitor value on the PCLK line of the camera (100n instead of 15pf). Unsoldering it fixed the issue. Still the question remains how to debug the core modules. The upload setting of the debug level seems to have a limited effect as came...

Re: ESP32-D0WDQ5

Figured the issue. My PCB had incorrect C13 capacitor value on the PCLK line (GPIO22) - 100n instead of 15pF as suggested on the reference diagram. After unsoldering it, the camera started working as expected.

Re: ESP32-D0WDQ5

Is it possible that the chip revision Q5 is the root cause of the problem? My perception is that it runs a bit slower and there avail heap size is less. No. Q5 is not a chip revision, it's a QFN package size indicator. The silicon in -Q6 and -Q5 packages is not correlated to the package. Thank you ...

ESP32S not returning frame buffer pointer in ESP32-CAM clone

I have made a custom PCB based on ESP32-CAM design and ordered it through EasyEDA, for my toy car project. The board is based on this diagram , which seems to be the official ESP32-CAM board schematics. The ESP32 - related part on my custom PCB is exactly like this ESP32-CAM, so it should work (or a...

Re: ESP32-D0WDQ5

I bought ESP32-S just recently, they were quite cheap on Amazon (~$3). I was hoping to use in my ESP32-CAM custom board. After soldering to the motherboard, the module works but runs hotter than usual (above 60C vs usual 47-50C). The camera on the board is initializing normally, the type of the came...
