UDPTCP vs HEIGAOLAPC Mini PC
processor performance
The HEIGAOLAPC uses an Intel J4115 processor, while the UDPTCP relies on a Celeron N2840. The J4115 is a quad-core chip designed for general computing tasks and media playback. It handles Windows 11 Pro smoothly out of the box. The N2840 is a dual-core unit with a lower thermal design power. It offers a max turbo frequency of 2.58 GHz. This chip is optimized for low-power industrial applications rather than heavy desktop workloads. If you need more processing power for multitasking or modern software, the J4115 provides a clear advantage. The N2840 is sufficient for basic routing or light Linux tasks.
operating system
The HEIGAOLAPC comes pre-installed with Windows 11 Pro. This allows you to use it immediately for standard desktop applications without additional setup. It also supports Linux and Ubuntu for development needs. The UDPTCP does not include a pre-installed operating system. You must install your own software, such as Linux, ESXI, or OpenWrt. This flexibility is ideal for users who want to build a specific network appliance or firewall. However, for general users who want a plug-and-play experience, the HEIGAOLAPC is more convenient. The UDPTCP requires technical knowledge to configure the BIOS and install drivers.
memory and storage
The HEIGAOLAPC includes 6GB of RAM and 128GB of eMMC storage. This configuration is ready to use for everyday tasks like web browsing and document editing. The UDPTCP offers no installed RAM or SSD in its base configuration. You must purchase memory and storage separately. It supports DDR3L SO-DIMM memory and SATA or mSATA drives. This modular approach allows you to customize the capacity to your exact needs. However, it adds complexity and upfront cost. For users who want a complete package with sufficient resources for light use, the HEIGAOLAPC is the better choice. The UDPTCP is better for those who already have components.
networking capabilities
The UDPTCP features two Gigabit Ethernet ports. This makes it suitable for use as a router, firewall, or soft router. It supports Wake on LAN and GPIO functions for industrial control. The HEIGAOLAPC has a single Gigabit Ethernet port plus Wi-Fi and Bluetooth. This wireless connectivity is useful for portable setups or environments where cabling is difficult. The UDPTCP lacks built-in Wi-Fi, requiring an external module if needed. If you need dual LAN connections for network segmentation or routing, the UDPTCP is superior. For general desktop use with wireless flexibility, the HEIGAOLAPC is more versatile.
form factor and size
The HEIGAOLAPC is a mini PC stick. It measures 5.51 inches in height and weighs only 3.53 ounces. It is designed to mount directly behind a monitor or TV, saving desk space. The UDPTCP is a small industrial box. It weighs 4 pounds and has a larger footprint. This box design provides more internal space for components and better heat dissipation for industrial environments. The UDPTCP also includes RS232 COM ports for legacy equipment. The HEIGAOLAPC is ideal for digital signage or home theater use. The UDPTCP is better for fixed installations in offices or factories where durability and connectivity matter more than size.
Which Mini PC Matches Your Needs

Users needing dual Ethernet ports for networking tasks
The UDPTCP features two Gigabit Ethernet ports, making it ideal for soft router or firewall setups like OPNsense or OpenWrt. It supports Linux and ESXI systems natively. You must add your own RAM and storage, but this modular approach allows you to customize the hardware for specific industrial or networking applications without paying for unused components.
Users prioritizing silent operation and portability
This fanless stick PC weighs only 3.53 ounces and measures just 0.35 inches thick. Its passive cooling design ensures zero noise, which is perfect for quiet offices or bedrooms. The integrated Wi-Fi and Bluetooth connectivity offer flexible placement options, allowing you to connect wirelessly to peripherals and networks without cluttering your workspace with cables.
Users requiring industrial connectivity options like COM ports
The UDPTCP includes two RS232 COM ports and GPIO support, which are essential for industrial automation and legacy equipment integration. It also offers a VGA output alongside HDMI, providing display flexibility for older monitors. The 6-layer PCB board is designed for stability in demanding environments, and you can configure it with SATA or mSATA drives for reliable data storage.
