The Changfan Tech CF-NANO300 is a fanless mini industrial PC that perfectly balances extreme compactness with industrial reliability. It utilizes a full-aluminum passive cooling chassis, eliminating the highest point of failure (the fan) while ensuring 0dB silent operation. It supports a wide operating temperature of -20°C to 50°C. It natively integrates 2 Gigabit Ethernet ports, 2 COM ports (jumper-switchable to RS485), and 6 USB ports. Its compact design allows it to be easily embedded into crowded electrical cabinets, equipment interlayers, or self-service kiosks.
Typical Application Scenarios
Factory Automation: Acts as a PLC host, SCADA/HMI terminal, or for machine tool data collection and MES uploading.
Edge IoT Gateway: Modbus/Profinet protocol conversion, paired with an optional 4G/WiFi module for data backhaul.
Digital Signage & Self-Service Terminals: 7x24 silent playback behind display screens, POS systems, self-service query machines, and smart lockers.
Medical & Lab Equipment: Ideal as a built-in host for analyzers requiring silence and cleanliness (optional medical-grade EN 60601-1-2).
Network & Security: Multi-LAN soft routers, basic firewalls, and NVRs.

VI. Frequently Asked Questions (FAQ)
Q1: How is the heat dissipation of the fully sealed fanless design in hot industrial sites?
A: Excellent. The NANO300 uses a full-aluminum finned chassis for passive cooling. The fanless design ensures 0dB absolute silence and prevents dust from being sucked in, which could cause short circuits. It supports an operating environment of -20°C to 50°C. As long as it is not placed in a completely sealed plastic box without convection, the aluminum housing can easily handle 7x24 continuous operation with an MTBF exceeding 50,000 hours.
Q2: The sensors at our site use the RS485 protocol. Does the serial port support this?
A: Yes. The CF-NANO300 comes standard with 2 COM ports, defaulting to RS232. However, a jumper is built into the motherboard. An engineer simply needs to open the chassis and switch the jumper to change the COM port to RS485 mode, allowing direct connection to RS485 sensors or PLCs without any extra conversion modules.
Q3: Our project is for smart lockers, and the PC needs to fit inside a very small cabinet. Can it be mounted?
A: It is highly suitable. The NANO300 measures only 127 x 136 x 40mm, making it much smaller than a traditional IPC (about the size of a thick book). Standard mounting holes are reserved on the bottom, supporting VESA wall-mounting or embedded installation. It fits easily into the narrow interlayers of smart lockers or self-service kiosks. Its low power consumption (6~25W) prevents excessive heat buildup in enclosed spaces.
Q4: If the customer needs to transmit data to the cloud via a 4G network, can a 4G module be built-in?
A: Yes. The NANO300 is designed with internal expansion interfaces. You can choose to add a WiFi/BT module or a 4G (optional GPS) module at the time of purchase. Antenna holes are pre-reserved on the chassis. Changfan Tech will install and test the module before shipping, so it is ready to use upon arrival.
Q5: We want to make bulk purchases. Can we remove unnecessary interfaces or customize our own system?
A: Changfan Tech supports deep OEM/ODM customization. If you only need a single LAN, we can provide that configuration. We can pre-install a customized Windows or Linux OS image, your proprietary business software, and even customize the boot logo and chassis silk-screen printing. For bulk projects, dedicated FAE engineers are assigned to ensure long-term stable supply (core materials remain unchanged for 3-5 years).
