I'm working on a project, and I required a camera for the project, and this ESP-32 CAM solution worked great. I have purchased other ones in the past, and this was my first with this vendor. I ordered 3 sets (6 total ESP32's), and I went through 4 of these units, and NONE of them would take a firmware upload. I reached out the vendor and asked for advice. In the few hours it took to get their reply, I kept at it, and discovered that these ESP32's will ONLY take a firmware upload, IF you use the 5V pin and the GND pin directly below it along with the TX and RX pins to function. IF you use the GND pin under the TX/RX pins, they will NOT. Since this is not mentioned anywhere on the product description, or reviews, I figured I let the vendor (Hosyond) know this and to share that with their product description. Hopefully, this will help someone else who is going through the same headaches. Also, don't forget to short the GPIO-0 and GND pins to put the ESP-32 CAM into "receiving" mode, so that you can upload your firmware, etc. Cheers- Read more
