Fish-eye Camera Module (OV2640)

Description

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

The hardware comes preloaded software, programmed by ESP-IDF. It is an application to run Wi-Fi camera. The output image is size 600*800, since it’s 2-Maga 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 web browser on your phone and visit 192.168.4.1
• Then here comes the picture. Video is about 5-6 frames per senconds. not super fast.

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

• 9-axis gyroscope (MPU6050)
• pressure sensor (BME280)
• Digital silicon microphone (SPM1423)
• Lipo Battery power pins

Note: M5CameraF is named differently when different hardware is selected. They follow the rules below.

M5CameraF_#_#… means optional hardware name follows “M5CameraF”.

• If configured with MPU6050, will be named M5CameraF_6050
• If also configured with microphone, will be named M5CameraF_6050_MIC
• If also configured with BME280, will be named M5CameraF_6050_MIC_BME280
• If also configured with battery, will be named M5CameraF_6050_MIC_BME280_BAT
