User Guide for Quectel Pi H1 Development Kit

Kit Overview

The Quectel Pi H1 Development Kit is an embedded solution centered on the Quectel Pi H1 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.

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.

Target Users

• Embedded Development Engineers: Carry out terminal-level embedded development (such as Linux driver adaptation, terminal application programming), verify hardware interface functions and software compatibility, quickly locate problems in terminal product development, and improve development efficiency;
• College Students: Complete course design and graduation projects in embedded systems, IoT, etc., participate in electronic competitions (such as the National College Students' Electronic Design Competition), accumulate practical experience based on terminal-level hardware, and connect with actual industry needs;
• Makers and Open-Source Project Enthusiasts: Develop open-source hardware projects (such as smart home terminals, environmental monitoring stations), DIY creative works, use the stability of terminal-level hardware to ensure long-term operation of projects, and quickly complete prototype construction relying on kit accessories;
• Enterprise R&D Personnel:
  • Terminal product R&D teams: Promote small-batch trial production and function iteration of IoT, industrial control, and edge computing terminal products, and accelerate the mass production process;
  • Embedded technical teams: Conduct terminal-level technical pre-research (such as low-power optimization, anti-interference design) to provide technical support for enterprises' terminal product layout;
• Intelligent Terminal Solution Providers: Provide customers with terminal basic solutions of "core hardware + adapted accessories", and support customized development for customers based on the kit, reducing customization costs and cycles.

Notes

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.

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 Quectel Pi H1.
• 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.
