ESP32 + Cam OV2640 Dev Board

 

ESP 32-CAM is small size camera module. It can operate independently as a minimum system. It has a footprint of only 40 x 27mm and has a deep sleep current of up to 6mA. We use ESP32-CAM for various IoT applications. It is suitable for many applications like home smart devices, industrial wireless control, wireless monitoring, QR wireless identification, and wireless positioning system signals.

ESP32-Cam is an ideal solution for various IoT applications. ESP32-cam has a DIP package. ESP32-Cam can be directly inserted into the backplane. a backplane is used for the rapid production of products, providing customers with high-reliability connection mode. And it is convenient for application in various IoT hardware terminals.

 

These pins are internally connected to the microSD card reader:

  • GPIO 14 is for CLK pin
  • GPIO 15 is for CMD
  • GPIO 2  is for Data 0
  • GPIO 4 is for Data 1
  • GPIO 12 is for Data 2
  • GPIO 13 is for Data 3
