    Brief overview

    M5CAMERA is the original decision to broadcast images in real time, created by a team of developers M5STACK. This device does not need settings and complex software (figure 1.1).

    Figure 1.1

    The front panel is centered with the camera lens. To the right of the lens there are holes under which there is a power LED. Below, under the lens, is the M5 logo. On the left side panel there is a button to restart the device. On both sides there are LEGO - compatible holes for the bushings for mounting the legs (figure 2).

    Figure 2

    There is a sticker with tips on the front side of the device. On the bottom side panel there are I2C (Groove) and USB Type C connectors one after another. The front panel and the front panel are partially connected by means of slot latches and fixed by screws of size M5 (figure 2.1).

    The heart of this device is the ESP32 module from ESPRESSIF. You can additionally purchase and connect motion sensors (I2C), temperature sensors (I2C), microphone (PDM), LEDs (GPIO), battery. The "eye of the device" is an OV2640 camera with a resolution of 2 Megapixels (figure 2.3).

    Note: do not attempt to adjust the focus of the camera by rotating the lens, otherwise it will damage the camera loop (figure 3).

    Let's start!

    Connect the camera to a power source (such as a USB cable). Wait for the red power LED to glow. Good. Now use your smartphone / tablet / computer to connect wirelessly to the access point that the camera has created automatically. Go to Settings (figure 4).

    Figure 4

    Refer to the wireless Wi-Fi settings section (figure 4.1).

    Figure 4.1

    Your device should find the wireless network M5Cam-test. Connect to this network (figure 4.2).

    Figure 4.2

    Good! Now open any new browser and go to http://192.168.4.1 (figure 5 - 5.2).
