ESP32-CAM module

The module contains the following hardware components:
  • ESP32-S ESP Module with u.FL Connector for External Antenna Connection (Change of antenna requires change jumper!)
  • OV2640 camera with flat flex connector for connection to ESP32-CAM
  • MicroSD Card Reader
  • Input / output pins
  • PSRAM module
  • Warning! The development board does not include a USB-UART converter
    Examples of possible applications with this development board:
  • Video stream as webserver
  • Webclient video stream
  • Linking with other systems - HomeAssistant, Tasmota, Xiaomi Smart Home, Domoticz, Custom
  • Face Detection
  • Real-time robot-controlled WiFi with image
  • Photography
  • Save photos to microSD card
  • Board Mount Options with Other Device
  • WiFi at 2.4GHz
  • Bluetooth at 2.4GHz
  • Technology data transfer
  • HTTP and HTTPS protocol (GET / POST)
  • MQTT and MQTTS protocol
  • Node.js / Websocket
  • Source code for a video stream server:
