AITRIP 3PCS ESP32-CAM development board test board WiFi + bluetooth module, ESP32 serial to WiFi small ESP32 camera module,Support STA/AP/STA + AP working mode for Arduino Raspberry Pi

Really powerful processor and good camera.

The boards work fine. One of the cameras had half the cable missing so had to be discarded. The board requires a USB programmer board or a cheap UART interface board to load programs as it has no direct USB connection like most ESP32 boards do. With a broken camera connection, I instead tried to install WLED onto one. The software installs but fails to proceed to the wifi login stage. I was not very impressed with the image frame rate of an example video stream over wifi. Not sure yet if they would be any good for video doorbells etc.

This board is ok, but found that developing it was problematic, eventually I used the followng in Arduino IDE, which worked for me:ESP32 Wrover ModuleUpload speed: 115200Flash frequency: 40MhzFlash mode: QIOPartitian Scheme: Huge app (3M No OTA/1M SPIFFS)

I needed one of these urgently, it's a good job I ordered three to cover myself.

Terrible product, None of the cameras were recognised by the ESPCAM… useless. will stick to the AIthinker boards for camera projects in future.

As mentioned in other reviews, getting the ESP=CAM board to accept a program is complex. I actually started a return because I could not get it to work, but after a bit more research I managed to get it to accept a sketch via the Arduino environment defaults and various items of hardware I already had.The first thing you need (obviously) is a USB to Serial converter that uses TTL (3.3 volt) logic, as anything higher on the ESP32 serial lines could burn it out. I initially powered the ESP32 from this item, having done so previously with various Arduinos. I connected a serial monitor from my PC to the ESP32 and noticed that is was starting up, then rebooting after a brownout - due to lack of power. To get round this, I powered it, initially via a breadboard power supply, but I found it very difficult to get at the reset button on the base of the ESP32 so I took it off the breadboard and reconnected everything via jump leads.So the final, working configuration is PC via USB cable to the USB/Serial converter set at 3.3V, then to the serial pins of the ESP32, marked U0T and U0R with the VCC to the ESP32 3.3 pin and GND to GND. The 5V pin and GND pin next to it were connected to a mains 5 volt power supply and pin1 was connected to the GND next to it via a push button switch.I started up a monitor (PuTTY) on the PC, held the push button down and reset the ESP32. PuTTY reported that the ESP32 was now waiting for a download, so I downloaded the Basic OTA sketch, to hopefully make sure I do not need to follow this procedure in future :-)

One of the three supplied cameras didn't work you can buy online but 33% not working not good enough

The seller should provide more info on board type and pins configuration. I have wasted so much time and still haven't got it working.
