Flashing Guide

This board has no built-in USB port. A CP2102 or CH340 USB-to-TTL adapter (5-pin) is required for flashing.

• Connect IO0 to GND before powering on to enter flash/boot mode
• Flash firmware using Arduino IDE or ESP-IDF
• Disconnect IO0 from GND and press reset to run your firmware
• In Arduino IDE: install Espressif ESP32 board package, select AI-Thinker ESP32-CAM
