M5Stack Fish-eye Camera Module (OV2640) M5Stack

DESCRIPTION

RETIRED PRODUCT – We’ve stopped stocking this product or it has been retired by the manufacturer and is no longer for sale. This page remains available for its resources and as a source of potential interest.

The M5CameraF is a development board designed for image recognition. It features an ESP32 (4M Flash + 520K RAM) chip and 2-Megapixel camera (OV2640). The M5CameraF offers plenty of storage, with an extra 4 MB PSRAM. It also supports image transmission via Wi-Fi and debugging through the USB Type-C port.

The hardware comes preloaded with software, programmed by ESP-IDF to run the Wi-Fi camera. The output image is size 600*800 since it’s a 2-Megapixel camera, you sure can optimize the software to output the maximum size of photos.

What this software can 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 a 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.

The hardware also comes with some reserved weld pad, just in case you want to put these chips back on board.
