User Guide for PI-SG565D Development Kit

1. Kit Overview

The PI-SG565D Development Kit is an embedded solution centered on the PI-SG565D single-board computer. It caters to the R&D and implementation of terminal products in fields such as the Internet of Things (IoT), industrial control, and edge computing, while meeting the needs of embedded development learning, open-source project verification, and course design. It aims to help enterprises shorten the mass production cycle of terminal products, provide developers, students, and makers with "terminal-level hardware + full-scenario adaptation" development support, and cover the entire process from "learning/verification to terminal product implementation".

The kit not only provides core hardware and mass production-level support required for terminal products but also adapts to scenarios such as embedded development, teaching practice, and open-source creation. Equipped with accessories and software resources that meet the stability requirements of multiple scenarios, it can support the early R&D, mid-term testing, and late small-batch deployment of terminal products, as well as meet the needs of development learning and project verification, enabling efficient reuse in multiple scenarios.

1.1 Application Scenarios

• End Product Implementation Scenarios: Mass production and deployment of IoT terminal devices (intelligent monitoring terminals, IoT gateways), implementation of edge computing terminals (lightweight AI recognition terminals), integration of industrial control terminals (equipment control terminals, data acquisition terminals), R&D of consumer-grade intelligent terminals (small smart screens, intelligent controllers);
• Embedded Development Scenarios: Embedded Linux driver development and verification, terminal-level application program debugging, hardware interface compatibility testing (such as USB/network port/camera interface adaptation);
• Teaching and Practice Scenarios: College embedded system course design, electronic competition project development (such as intelligent car terminals, environmental monitoring terminals), embedded skills training;
• Open-Source and Maker Scenarios: DIY of open-source hardware projects (such as smart home control terminals, creative display devices), prototype verification and function iteration of maker works.

3. Quick Start with the Kit

This chapter provides a "10-minute startup" process to help developers quickly complete hardware connection, system startup, and basic function verification without in-depth understanding of underlying details.

3.1 Preparation

Before starting the connection, please confirm that the following items are ready:

• The complete PI-SG565D Development Kit (check against the "Kit List" for no missing items).
• Additional items needed:
  • A power adapter supporting 5V/5A, 9V/3A, or PD fast charging protocol.
  • A display supporting USB-C DP or HDMI (resolution is recommended to be 1080P or higher).
  • USB keyboard + mouse (wired or wireless, need to be connected to the USB port of the single-board computer).
  • A router with internet access (for network debugging of the single board).

3.2 Hardware Connection (Key Steps, Operate in Order)

⚠ WARNING
During connection, disconnect all power supplies first to avoid hardware damage caused by hot-plugging interfaces!

The PI-SG565D is pre-installed with the Debian 13 system image at the factory, so there is no need to flash the image again. Just follow the steps below:

1. Display Connection:
   • Option 1 (HD): Connect one end of the USB-C DP display cable to the USB&DP interface of the single-board computer, and the other end to the USB-C interface of the display;
   • Option 2 (compatible): Connect one end of the HDMI cable to the HDMI interface of the single-board computer, and the other end to the HDMI interface of the display.
2. Peripheral Connection: Connect the USB keyboard and mouse to the two USB-A interfaces of the single-board computer; for wireless keyboards and mice, insert the receiver into the USB port.
3. Camera Connection: Find the camera interfaces on the single board (usually marked camera1 and camera2), point the gold finger surface of the camera cable towards the onboard HDMI interface, gently insert it, and fasten the buckle (avoid pulling the cable hard).
4. Network Connection: Connect one end of the network cable to the gigabit network port of the single-board computer, and the other end to the network port of the router (ensure the router is connected to the internet).
5. Power Supply Connection: Finally, connect the USB-A end of the USB-A power cable to the power adapter, and the USB-C end to the power port of the single-board computer (usually marked POWER IN).

3.3 System Startup and Initialization

1. Start the System:
   • Turn on the display power and confirm that the display input source has been switched to the corresponding interface (such as USB-C or HDMI).
   • Connect the single board to power (plug in the power cable). At this time, the power indicator of the single-board computer (usually red) will be on steadily, and the system indicator (usually green) will flash, indicating that the system is starting.
   • Wait for about 1-2 minutes, and the display will show the system login interface.
2. Initialization Settings:
   • Login: The default username is pi and the password is quecpi.
   • System update: Open the terminal (shortcut key Ctrl+Alt+T) and enter the following command to update the system (ensure the network is connected):

   sudo apt update && sudo apt upgrade -y

5. Notes

5.1 Hardware Usage Specifications (Avoid Damage)

• Power Supply Restrictions:
  • Please use the USB-A power cable (5A) provided with the kit. Do not use a power supply with a current lower than 3A (such as a mobile phone charger), otherwise, it may cause insufficient power supply to the single board and frequent crashes;
  • If it is necessary to connect high-power modules (such as motors), power the modules separately. Do not take power through the single board's USB port or GPIO port (to avoid overload and board burnout).
• Interface Operations:
  • When plugging or unplugging accessories (such as camera cables, network cables), the single board's power must be disconnected first. Hot-plugging may burn the interface chip;
  • The USB&DP interface only supports DP display + power output and cannot supply power to the single-board computer.
• Environmental Requirements:
  • Operating temperature: -20 ~ +70 °C. Do not use in high-temperature (such as direct sunlight), humid (humidity > 80%) or dusty environments;
  • Electrostatic protection: Touch a metal object to release static electricity before operation. Do not directly touch the chip pins on the single board with your hands.

5.2 System and Software Notes

• System Compatibility:
  • Only official system images are supported. Do not flash images from other single boards (such as Raspberry Pi), otherwise, problems such as incompatible drivers and failure to start may occur;
  • If you need to customize the system, you must use the Yocto Linux SDK for development to ensure that the kernel version and driver modules match the PI-SG565D.
• Software Operations:
  • Do not modify the core configuration files in the /boot partition (such as config.txt). Incorrect modification may cause the system to fail to start (it is recommended to back up the file before modification);
  • When installing software, prefer to use the apt command to download from official sources. Avoid installing DEB packages from unknown sources to prevent system poisoning or crashes.
