Hello, I bought an ESP32 development board recently and and notice something weird, has one of the GND pins connected to GPIO 11
This bottom right GND I marked in green is connected to that pin on the esp32, checking on the internet it seems that it is the GPIO 11, but why do its labed as GND? (it does not work as ground definitely) Coud it be an PCB design error?
The pin marked GND that you are pointing out should be marked CMD, which is GPIO 11, rather than GND
Somebody has misread the label of the original board when designing the clone
To quote from ESP32 Pinout Reference: Which GPIO pins should you use? | Random Nerd Tutorials
GPIO 6 to GPIO 11 are exposed in some ESP32 development boards. However, these pins are connected to the integrated SPI flash on the ESP-WROOM-32 chip and are not recommended for other uses. So, don’t use these pins in your projects:
It seems to be a badly designed clone. The PBC seems to be following the pinout on the Instructables page (attached picture). The labels might be wrong.
Given this mistake, might be a good idea to check all the pins in case there's another mistake.
makes sense, you think this board ESP module could be a copy too or it is just an copy version of the DEVKIT board but with and original ESP-WROOM-32 module?
Hard to tell, but from the picture, it looks like the module is original, just the dev board is a clone.
