ESP32-CAM / ESP-EYE modul

Získať ESP-CAM / ESP-EYE zdarma:

  • Všetky dosky už boli rozdané, ďakujem za záujem a účasť.

  • Modul obsahuje tieto hardvérové komponentny:
  • ESP modul ESP32-S s konektorom u.FL pre pripojenie externej antény (zmena vyžaduje aj prepájkovanie jumpra! )
  • OV2640 kamera s plochým flex konektorom pre pripojenie k ESP32-CAM
  • Čítačka pre microSD kartu
  • Vstupno-výstupné piny
  • PSRAM modul
  • Pozor! Vývojová doska neobsahuje USB-UART prevodník
    Príklady možných aplikácii s touto vývojovou doskou:
  • Video stream ako webserver
  • Video stream ako webclient
  • Prepojenie s inými systémami - HomeAssistant, Tasmota, Xiaomi Smart Home, Domoticz, vlastné
  • Detekcia tváre
  • Real-time ovládaný robot prostredníctvom WiFi siete s obrazom
  • Fotografovanie
  • Ukladanie fotografií na microSD kartu
  • Možnosti pripojenia dosky s iným zariadením
  • WiFi na 2.4GHz
  • Bluetooth na 2.4GHz
  • Prenos dát do internetu technológiami
  • HTTP a HTTPS protokol (GET/POST)
  • MQTT a MQTTS protokol
  • Node.js / Websocket
  • Zdrojový kód pre webserver so streamom videa:
