HKAIOT Fanless Firewall Mini PC Alternatives: 6 Similar Picks Compared

How these alternatives differ

HiGOLE Fanless Mini PC Stick

The HiGOLE Fanless Stick PC shifts form factor from a box to a compact stick. It uses an Intel Celeron processor instead of the AMD A4, which may offer different performance characteristics for basic tasks. Both units provide 4GB of RAM and silent operation. The HiGOLE model includes Windows 10 and 64GB of eMMC storage, whereas the HKAIOT uses an mSATA SSD. The HiGOLE lacks the multiple serial ports found on the HKAIOT, making it better suited for simple digital signage or office work rather than industrial legacy connectivity. You should choose this if you need a smaller footprint and do not require RS232 interfaces.

HiGOLE 15.6-Inch Fanless Android All-in-One PC

This HiGOLE All-in-One PC integrates a 15.6-inch display, removing the need for an external monitor. It runs Android, which differs significantly from the Windows environment typically used with the HKAIOT. Both are fanless and target industrial use. The HiGOLE offers 4GB of RAM and 64GB of storage, similar to the HKAIOT base configuration. However, the integrated touch screen and rugged design make it ideal for kiosks or control panels. The HKAIOT provides more traditional PC ports and dual display outputs via HDMI and VGA. Select this alternative if you require an all-in-one solution with touch capability for industrial deployment.

UDPTCP Fanless Industrial Mini PC

The UDPTCP Fanless Industrial Mini PC is designed specifically for Linux-based networking tasks. It features dual network interfaces, which is a key advantage over the single Gigabit LAN port on the HKAIOT. Both systems offer 4GB of RAM and passive cooling. The UDPTCP model supports 64GB of SSD storage. Its dual WAN capability makes it superior for firewall or soft router applications. The HKAIOT is better for general industrial computing with serial ports. Choose the UDPTCP unit if your primary goal is building a dedicated Linux router or firewall rather than a general-purpose industrial computer.

WEIDIAN Fanless Core i5 Industrial Mini PC

The WEIDIAN Core i5 Mini PC offers significantly more processing power with an Intel Core i5 processor compared to the AMD A4 in the HKAIOT. It also doubles the memory to 8GB and provides 512GB of SSD storage versus 64GB. Both are fanless and support dual display outputs. The WEIDIAN includes dual Gigabit Ethernet ports, enhancing network flexibility for industrial setups. The HKAIOT retains the advantage of multiple RS232 serial ports. This alternative is better for users who need higher performance for office or industrial applications and do not require legacy serial connectivity. It is a more robust choice for multitasking.

AZULLE Access Pro Fanless PC Stick

The Azulle Access Pro is a stick PC, offering a much smaller form factor than the box-style HKAIOT. It uses an Intel N100 processor, which is more modern than the AMD A4. Both provide 4GB of RAM and 64GB of storage. The Azulle runs Windows 10 and features a fanless design. It lacks the serial ports and multiple USB ports of the HKAIOT. This unit is ideal for digital signage or IoT deployments where space is critical. The HKAIOT is better for tasks requiring extensive peripheral connections. Pick the Azulle if you prioritize low profile and silent operation for specific IoT or signage roles.

WEIDIAN Fanless N100 Mini PC

The WEIDIAN N100 Fanless Mini PC uses an Intel N100 processor, offering better efficiency than the older AMD A4. It includes dual Gigabit Ethernet ports, unlike the single port on the HKAIOT. Both units have 4GB of RAM, but the WEIDIAN provides 128GB of SSD storage, double the capacity of the HKAIOT. The WEIDIAN runs Windows 11, while the HKAIOT typically targets industrial legacy systems. The WEIDIAN lacks the RS232 ports found on the HKAIOT. This alternative is suitable for dual-network industrial setups where higher processing power and modern operating systems are preferred over legacy serial connectivity.
