Hosyond 2Pcs ESP32-CAM Wireless WiFi+Bluetooth Development Board with Camera Module OV2640 Compatible with Arduino

At first I could not get the Arduino IDE to communicate with either of the esp32 cam boards so I contacted the seller. On both occasions I got next day responses. Turns out the issue was my FTDI adapter went bad. With a new adapter all worked fine. In the Arduino IDE choose the AI Thinker ESP32-CAM and follow the standard wiring scheme for FDTI adapters. Don't forget to short IO0 to ground on the Esp board while uploading code then remove when done.

These cameras work fine

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-

I have a little hobby experience with SoCs. I have an FTDI that I use with other SoCs such as JeeLink and several Arduino clones and have never had any bad experiences with them. I ordered 4 of these. All of them showed their start up logs when connected to my FTDI. Only one of them would actually take a program and then only after I slowed the write speed down to 9600. After it was written, it would start up and connect to my WiFi, but as soon as I tried to load its web page, the device would crash. I've tried cleaning off the crusted residue that was on the boards with no improvement. I tried resoldering the headers with no improvement. I verified my power supply was pushing a clean 5v (±0.15V) the whole time the device was running. I finally tried reflowing each of the boards at 355° F which fully destroyed them. There other brands of this device from other sellers for not much more money. I will leave reviews on those products when I receive them.

Perfect, very robust board and decent camera
