ESP32CAM-PSRAM is a development board for image recognition. It features an ESP32(4MB Flash + 520KB RAM + 4MB PSRAM) chip and 2-Megapixel camera (OV2640).
The module offers plenty of storage with an extra 4 Mbyte PSRAM. It also supports image transmission via Wi-Fi and debugging through USB Type-C port.
The hardware comes with preloaded software, programmed by ESP-IDF. It is an application to run Wi-Fi camera. The output image resolution is 600*800, since it's 2MP camera, you sure can optimize the software to output a better resolution image.
Using processes:
Power the board via USB type-C or GROVE
Use your phone to Wi-Fi scan an AP name start with 'm5stack-' and click to connect this AP.
Open up web browser on your phone and visit 192.168.4.1
Then here comes the picture. Video is about 5-6 frames per seconds. not super fast.

NOTE:
Camera Power Down pin does not need to be connected to ESP32 GPIO. Instead it may be pulled down to ground with 10 kOhm resistor.
