You will need an external FTDI or CP2102 USB-to-serial adapter to upload sketches. Connect TX, RX, GND, and 5V accordingly, and pull GPIO0 to GND before flashing.\u003c\/p\u003e\n\u003ch4\u003eQ: What microSD card format and size does the ESP32-CAM OV2640 module support?\u003c\/h4\u003e\n\u003cp\u003eA: The ESP32-CAM supports standard TF (microSD) cards formatted as FAT32, with a maximum supported capacity of 4GB. This is used primarily to store JPEG images captured by the OV2640 camera locally without requiring a network connection.\u003c\/p\u003e\n\u003ch4\u003eQ: Can the ESP32-CAM be used for live video streaming over WiFi?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The ESP32-CAM with OV2640 camera is capable of MJPEG streaming over Wi-Fi.
