CWWK F4 4-Port 2.5GbE Firewall Mini PC

The CWWK F4 is a fanless 4-port 2.5GbE firewall mini PC based on CWWK's Pioneer N-Series motherboard. It supports Intel N150, Core i3-N305, and Core 3 N355 processors, four Intel i226-V 2.5GbE LAN ports, DDR5 memory, flexible NVMe storage expansion, VESA mounting, optional 8010 fan installation, and an Official aluminum chassis with a copper alloy heat conductive sheet and internal heat pipe.

Intel N150, N305 and N355 Processor Options

The F4 supports Intel N150, Core i3-N305, and Core 3 N355 processor configurations. N150 provides a low-power platform for firewall, routing, VLAN, and VPN workloads, while N305 and N355 provide additional CPU resources for virtualization, containers, and multi-service home lab deployments.

N150 4 cores / 4 threads for OPNsense, pfSense, OpenWrt, routing, VLAN segmentation, and low-power networking.

N305 8 cores / 8 threads for Proxmox, virtual firewalls, containers, VPN services, and heavier network workloads.

N355 8 cores / 8 threads for more demanding virtualization and multi-service home lab deployments.

Four Intel i226-V 2.5GbE Network Ports

Four Intel i226-V 2.5GbE LAN ports provide dedicated physical interfaces for WAN, LAN, VLANs, NAS systems, wireless access points, cameras, IoT devices, and isolated network segments.

4 × 2.5GbE Assign dedicated interfaces to WAN, LAN, NAS, access points, cameras, IoT devices, or independent lab networks.

Multi-WAN Configure multiple interfaces for separate upstream connections, failover, or independent gateway routes.

Network Segmentation Separate trusted devices, servers, guests, IoT equipment, and lab systems through physical ports or VLANs.

Pioneer Motherboard with PCIe 3.0 x4 NVMe Expansion

The F4 uses CWWK's Pioneer N-Series motherboard with a dedicated NVME1 PCIe 3.0 x4 expansion path. NVME1 can connect to the separately sold 1V4 adapter board, dividing the x4 connection into four PCIe x1 channels for four M.2 2280 NVMe SSDs.

Up to 5 NVMe or 4 NVMe + SATA Storage Expansion

The F4 provides two storage expansion paths. NVME1 uses the PCIe 3.0 x4 connection with a separately sold 1V4 adapter board to support four M.2 2280 NVMe x1 SSDs. NVME2 provides one additional PCIe 3.0 x1 NVMe connection by converting the M.2 Wi-Fi E-Key interface to M-Key.

NVME1: 4 × NVMe PCIe 3.0 x4 connects to the 1V4 adapter board and expands into four M.2 2280 NVMe PCIe x1 SSD positions.

NVME2: +1 NVMe The M.2 Wi-Fi E-Key interface can be converted to M-Key through an adapter to provide one additional PCIe 3.0 x1 NVMe connection.

Flexible Storage Layout Configure the system with up to 5 NVMe SSDs, or use 4 NVMe SSDs together with one SATA3.0 drive.

NVME2 and SATA3.0 cannot be used at the same time. To use the M.2 Wi-Fi slot for a Wi-Fi/BT module, remove the E-Key to M-Key storage adapter and install the wireless module instead.

Official Chassis Fanless Copper Alloy Sheet Heat Pipe Dust-Resistant VESA Mounting

The F4 uses CWWK's Official aluminum chassis with a clean rectangular profile. Its passive cooling system combines a copper alloy heat conductive sheet, internal heat-conduction structure, heat pipe, aluminum enclosure, and external cooling fins.

The copper alloy sheet provides high-efficiency thermal conduction from the processor area, while the heat pipe transfers thermal energy toward the larger chassis surface for passive dissipation without requiring continuous fan operation.

Copper Alloy Heat Conductive Sheet High-efficiency copper alloy material helps transfer heat away from the processor area quickly.

Heat-Conduction Structure Provides a direct thermal path between the main heat source and the internal cooling system.

Internal Heat Pipe Transfers thermal energy toward the larger aluminum chassis heat-dissipation area.

Passive Fanless Cooling The aluminum enclosure and external fins release transferred heat without continuous fan operation.

8010 Fan and 2.5-Inch SATA Installation

The F4 operates as a fanless system but supports an optional 12V 4-pin 80 × 80 × 10 mm 8010 cooling fan when additional airflow is required. The chassis also supports a 2.5-inch SATA drive when the system is configured for the 4-NVMe + SATA storage layout.

OPNsense, pfSense, OpenWrt and Proxmox Compatibility

The F4 supports OPNsense, pfSense, OpenWrt, Proxmox, Linux, Ubuntu, Debian, ESXi, Windows, and other compatible x86 operating systems. Its four physical 2.5GbE interfaces and flexible storage architecture make it suitable for firewall routing, VLAN segmentation, VPN gateways, storage-focused home labs, and virtualized network services.

Firewall & Routing Deploy OPNsense, pfSense, OpenWrt, VPN gateways, VLAN routing, and multi-interface network services.

Storage-Focused Home Lab Use up to five NVMe SSDs for virtual machines, containers, local services, and compact lab storage.

Fanless Network Appliance Run network services with passive cooling while retaining optional 8010 fan expansion when additional airflow is required.

Front and Rear I/O Connectivity

The F4 provides front and rear interfaces for networking, system installation, display output, USB peripherals, storage connectivity, and power. Four Intel i226-V 2.5GbE LAN ports provide the primary connectivity for firewall and routing deployments.
