ESP32-WROVER-E Kamera Entwicklerboard Set beinhaltet:
- 1Stück ESP32-WROVER-E 4MB Flash 8MB PSRAM Entwicklerboard
- 1 Stück OV2640 2 Megapixel UXGA Farbcamera
Das ESP32-WROVER-E Kamera Entwicklerboard basiert auf dem ESP32-WROVER-E-N4R8 von Esspressif in Kombination mit 4MB Quad SPI Flash und 8 MB Quad SPI PSRAM.
ESP32-WROVER-E Kamera Entwicklerboard
Die OV2640 Farbkamera ereicht eine UXGA Auflösung von 1632×1232 Pixel und verfügt über einen SCCB (Serial Camera Control Bus).
Die generelle Spannungsversorgung erfolgt dabei über eine integrierte USB Micro Schnittstelle.
Ferner verfügt das ESP32-WROVER-E Kamera Entwicklerboard über einen CH340 USB TTL Konverter, sodass eine direkte, serielle Kommunikation über die USB Micro Schnittstelle erfolgen kann.
