Description:
M5Camera is a development board for image recognition. It features an ESP32(4M Flash + 520K RAM) chip and 2-Megapixel carmera(OV2640).M5Camera 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)
– Analog MIC (SPQ2410)
– Lipo Battery power pins
Note:
M5Camera is named differently when different hardware is selected. They follow the rules below.
M5Camera_#_#… means optional hardware name follows “M5Camera”.
If configured with MPU6050, will be named M5Camera_6050
If also configured with microphone, will be named M5Camera_6050_MIC
If also configured with BME280, will be named M5Camera_6050_MIC_BME280
