Review on 🔍 Enhanced SEO: 2-Pack ESP32-CAM WiFi Bluetooth Development Board with OV2640 Camera Module by Larry Breeze

There were two ESP32 CAM controllers with cameras in the package and both worked, contrary to some reviewers who did not. Here's a quick way to check if your device is working: First, you need to connect the camera's ribbon cable to the control board. To do this, lift the black plastic locking bar (see photo) and feed the cable as low as possible so that when you push the locking bar down to lock the cable, the bar covers the white line on the cable connector. . According to some other reviewers, I used a powered USB hub to power the USB to TTL converter. Haven't messed with the RCV DATA or TX DATA pins (yet); For this rapid test, all you need is nutrition. The ESP32-CAM comes with pre-flashed demo firmware that starts a web server and creates a WiFi hotspot called CAM-aa:bb:cc:dd:ee:ff (with some other hexadecimal digits, probably a MAC address. Use Use your smart phone or computer to connect to this hotspot (without password), then type 192.168.4.1 in the browser, this will bring up the demo firmware, which you can use to set all kinds of camera parameters, as well as stream videos and images Now you know blithely whether your device or DOA.Mine was working with 3.3V or 5V (fed to the appropriate pin of the board, of course.) Of course, your real goal is to write new firmware or hack the released one and to flash Don't worry that there are no instructions included with the product - just search for "ESP32-CAM" and you will see many websites and videos about it Now you need the USB to serial converter TX- Connect data to the chip's RX data and vice versa. I have successfully used Arduino development software running on Raspberry Pi.
