Frequently Asked Questions (FAQ)

Q: How do I connect this board to my computer to program it?
A: Unlike standard Arduino boards or NodeMCUs, the ESP32-CAM does not have a built-in USB port. To upload code via the Arduino IDE, you will need a separate FTDI USB-to-TTL serial converter. You must connect the TX, RX, 5V, and GND pins, and briefly short GPIO 0 to GND to put the board into flashing mode.

Q: My video feed looks blurry. Is the camera broken?
A: Most likely not! The RHYX-M21-45 camera lens has a manual focus ring. Carefully twist the small black lens ring on the camera module clockwise or counter-clockwise until the image on your stream sharpens.

Q: Why does my ESP32-CAM keep resetting or suffering from "brownout" errors?
A: The ESP32 chip and the camera draw significant current spikes, especially when using Wi-Fi or turning on the flash LED. If you are powering it from a weak USB port or thin jumper wires, the voltage will drop, causing a "brownout detector was triggered" error. Ensure you are using a robust 5V power supply capable of providing at least 1A to 2A of current.
