Review on 📷 KeeYees 1 Set WiFi + Bluetooth Camera Module 4M PSRAM Dual-core 32-bit CPU Development Board with OV2640 2MP Camera Module – Support Image WiFi Upload by Steven Darkshnar

Programming the board was a bit difficult. To turn it on, 5V was applied to the 5V line rather than the Vin line. (3.3v to 3.3v line didn't work either). It appears that the reset pin is not broken, so programming via the serial port will require a manual reset of the board. Using the CameraWebServer example thumbnail, the camera should have been defined as CAMERA_MODEL_AI_THINKER and not the default CAMERA_MODEL_WROVER_KIT. The camera has a very noticeable rolling shutter, but I think it's a software issue.
