2. Specification parameters

3. Description of hardware interface functions

IMX283 L1117C Camera module:

It can shoot 20 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.

PWM interface:

Through the above interface, the PWM function interface is introduced, which can control the camera mode switching, taking photos, recording and other functions.

ADC five-way keys:

Support one ADC five-way key interface, can connect, down, left, right, confirm five keys, support external keys, control camera startup and shutdown.

Control serial port:

Supports RX3 and TX3. You can set and control the camera through the Uart serial port. One analog video CVBS (TV-OUT) signal output is reserved, and the CVBS function can be customized if required.

DC power supply interface:

9~24V power supply can be used to control the automatic startup of the camera. Support three power supply at the same time, namely WiFi board DC power supply, motherboard battery power supply, Type-C USB power supply, can also be used as a single power supply.
