ESP32-D0WD with OV2640 camera.

Postby Hairyloon » Wed Oct 02, 2019 5:09 pm

I've been trying to get one of these ESP32-Cam modules to work without success.
The first problem is that it keeps giving me "Brownout detector was triggered". Usually, if I leave it running then it settles down and gives me some other error: usually "camera probe failed with error 0x20001", but I've also had "camera: failed to set frame size e (4745) camera demo: camera init failed with error 0x20002" on one of them.

I'm currently trying "esp-who" from but that one won't settle down out of the brown out cycle.

I'm reasonably sure that it has plenty of power. I'll find a meter in a mo and check the voltages...

I was able to get esp-CAM it working electrically with this tutorial: ... duino-ide/

I use this cable to flash to it: ... 06ZYPLFNB/

I highly recommend the esp-eye only because of the additional ram built into the board. It's likely to have better luck with power issues and consistent working capability.
