3. Interface Description

IMX377 L1812C6 Camera Module:
IMX377 L1812C6 Camera Module supports capturing 12-megapixel high-resolution photos and recording 4K video at 30FPS. Utilizing an ICM-40607 gyroscope, it enables advanced multi-axis EIS (Electronic Image Stabilization) for enhanced image stability.
USB Type-C Interface:
This interface supports 5V power input per the USB standard, providing power to the camera module and enabling battery charging. When connected to a computer via USB, it allows direct access to files on the TF card (functioning as a mass storage device) and can also operate as a PC camera (USB webcam). Additionally, it reserves one camera control UART3 and one camera debug UART1 serial port (serial port functions require the dedicated G1-USB serial adapter board).
Micro HDMI Interface:
The Micro HDMI interface supports video signal output at up to 4K@30FPS.

Battery Interface:
Supports operation via a battery with a voltage range of 6.8V to 8.4V. A high-voltage, high-density lithium battery within 7.4V to 7.7V is recommended for optimal performance.
Fill Light Interface:
Two fill light interfaces are provided for connecting expansion light panels (supporting both white light and IR infrared), enabling auxiliary lighting for the device.
Dual Control Buttons:
Comprises a Power Button (Button A) and a Confirm Button (Button B). The Power Button controls power on/off and mode switching, while the Confirm Button is used for photo capture and video recording.

UART3 Serial Port Interface:
This UART3 serial port allows for camera configuration and control through command input.
Ethernet Interface:
Connect to a computer, router, or video transmission board via Ethernet cable (according to pin definition) for RTSP stream pulling.
DC Power Interface:
Supports 9V-24V DC power input or 8V-16.8V lithium battery power supply, enabling automatic camera startup.
PWM Interface:
This interface provides PWM functionality, allowing control over camera mode switching, photo capture, and video recording.
ADC 5-Way Button:
Supports one ADC 5-way button interface for up, down, left, right, and confirm operations. It enables external button control for powering the camera on and off.
