ESP32CAM
Description
ESP32CAM is an image recognition development board. It features an ESP32 (4M Flash + 520K RAM) chip and 2-Megapixel camera (OV2640). It also supports image transmission via Wi-Fi and debugging through USB Type-C port.
The hardware comes with a preloaded software, programmed by ESP-IDF. The purpose of the pre-loaded software is to operate the Wi-Fi camera. The camera output image has a resolution of 600*800, since it's 2MP camera it's possible to optimize the software to output a bigger resolution of photos.
What can the software do?
- 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.
