ESP32S UNO PSRAM not creating hotspot

I would not connect a 9V battery to an ESP32 board. I believe they only run on 5V or USB. You will probably fry your board if you do this. I guess you could create a voltage divider circuit to provide 5V from a 9V battery.

 

I have the Arducam IoTai which, I believe is the same as the Arducam ESP32 PSRAM. I had to purchase a good USB Data Cable to make it work properly.

Hi sajjad_P,

Hi,

If you use the ESP32 UNO PSRAM board, you can refer to this link:https://github.com/ArduCAM/ArduCAM_ESP32S_UNO_PSRAM/tree/master/libraries/ArduCAM/examples/ESP32_Camera/ArduCAM_ESP32_PSRAM_OV2640_Capture2SD

@Arducamjyh i have tried it but its for capturing pictures not for video… its working… but i am looking for video recording…
