| Dec 11, 2019 at 1:37 | comment | added | LonelyLodge | Yes I have been toggling to io wire appropriately. I think the board is just bricked I ordered another one and I'll see if it works. If there are any other suggestions I'm all ears | |

| Dec 5, 2019 at 4:31 | comment | added | LonelyLodge | Yes I have removed the jumper from io 0. Yes it is quite bright so it is probably the camera's flash light. Weird that it worked to upload once then with the same setup it hasn't worked since then. | |
| Dec 4, 2019 at 8:15 | comment | added | Juraj♦ | to run the sketch remove jumper from io 0. by yellow light you mean the camera's flash light? on USB it should not have problem with current draw, but the manual recommends capacitors on 5 V Vcc to cover current draw spikes by WiFi | |
| Dec 4, 2019 at 5:12 | comment | added | LonelyLodge | I'm not sure if maybe it is not getting enough power, I think I'll try powering it with a lipo to give it more current, and maybe slightly above 5V, like 5.3 or so since there is a regulator. The yellow square with the +/- is also lighting up, when powering now, not sure if this means low voltage or something. Couldn't find any documentation on that. | |
| Dec 4, 2019 at 5:10 | comment | added | LonelyLodge | Yes I was going to say VCC has a bridge to 3.3V and 5V so it is likely an additional output based on the input power. I am still having issues with this chip, I was able to upload the one time by connecting 5V from FTDI to VCC on ESP. Now that is no longer working and it seems like the device is trying to boot but failing (I can see jumbled up output on a serial output when it tries to boot). | |
| Dec 3, 2019 at 19:01 | comment | added | Juraj♦ | there are solder bridges labeled 3.3 V and 5 V next to Vcc pin | |
| Dec 3, 2019 at 18:51 | comment | added | Juraj♦ | so I was not right. in the schematic Vcc pin is connected to both 5 V and 3.3 V. is there some jumper next to the Vcc pin, which I can't see on photos? use 5 V pin to power the board over voltage regulator. schematics from Adriano's link github.com/SeeedDocument/forum_doc/blob/master/reg/… | |
| Dec 3, 2019 at 2:03 | comment | added | LonelyLodge | @Juraj was right, connecting 5V to VCC worked! Seems like the diagram above is wrong then because the pin labelled 3.3V on the ESPCAM32 is just an output pin. The only issue I have having now is that my board is extremely hot when doing it this way, too hot to touch in most parts. Is this due to this connection or a different issue | |

| Dec 2, 2019 at 9:09 | comment | added | Juraj♦ | the FTDI can't supply enough current for the ESP32 from the 3.3 V pin | |
