3. Description of hardware interface functions

OS12D40 L143_004 Small camera module:

It can shoot 11 million pixel HD photos and record 4K@30FPS videos.

USB Type-C interface:

This port supports USB standard 5V power input to power the camera module and charge the battery. USB interface connected to the computer can directly read the files in the TF card, used as a U disk, can also be used as a PCCAM USB camera. A camera control serial port UART3 and a camera debugging serial port UART1 are reserved on the USB interface (the serial port function can be used with a special G1-USB serial port adapter board).

Micro HDMI HD interface:

Adopt Micro HDMI interface output, up to support 4K@30FPS video signal output.

Battery interface:

The battery voltage ranges from 6.6V(low-power shutdown) to 8.8V. It is recommended to use high voltage and high-density lithium batteries from 7.4V to 7.7V. (Special note: up to 12V access can be supported, when accessing non-7.7V battery power, USB interface cannot be used to charge)

Two buttons:

They are the power key (A key) and the confirm key (B key), the power key controls the switch on and off, the switch mode, and the confirm key controls the camera and video recording.
