Overview

Ai-Thinker ESP32-CAM is an ESP32-based development board produced by Ai-Thinker <https://en.ai-thinker.com/>_.

Hardware

ESP32-CAM features the following components:

ESP32S module
8MB PSRAM
24-pin FPC connector (for OV2640 Sensor)
MicroSD card slot
Flash LED

.. note::

ESP32's GPIO4 on the ESP32 is shared between the MicroSD data pin and the onboard flash LED.

Sample Applications

Applications for the esp32_cam board can be built and flashed in the usual way (see :ref:build_an_application and :ref:application_run for more details); however, an external FTDI USB to TTL Serial Adapter is required since the board does not have any on-board debug IC.

The following pins of the Serial Adapter must be connected to the header pins:

VTref = VCC
GND = GND
TXD = U0TXD
RXD = U0RXD
Boot = GPIO0 (Must be low at boot)
