BIOSTAR BIWCL-PAT: 3.5-inch industrial SBC with Intel Wildcat Lake, dual 2.5GbE

BIOSTAR has introduced the BIWCL-PAT, a 3.5-inch industrial single-board computer in the 148 x 102mm form factor. The board uses Intel's Core 3 through Core 7 'Wildcat Lake' processors with 15W TDP, includes three M.2 slots for NVMe storage and wireless modules, and offers four serial interfaces plus an 8-bit digital I/O header for industrial use. BIOSTAR lists Ubuntu 24.04 as a supported operating system alongside Windows 11 IoT Enterprise 24H2.

BIWCL-PAT hardware details

• SoC options: Core 3 304 (1P+4LPE cores) through Core 7 360 (2P+4LPE cores), all at 15W TDP; Xe3 graphics with 1-2 cores
• NPU: 15-17 TOPS on most SKUs; Core 3 305 omits the NPU entirely
• Memory/storage: Single DDR5-6400 SO-DIMM up to 64GB; M.2 M-key 2242/2280 with PCIe 4.0 x2 for NVMe
• Display outputs: HDMI 2.1 (4K), DisplayPort 1.4 (4K), internal LVDS up to 1920x1200; triple independent display support
• Networking: Dual 2.5GbE via Intel i226-LM and i226-V; optional Wi-Fi/Bluetooth (M.2 E-Key) and 4G/5G cellular (M.2 B-Key with SIM)
• Industrial I/O: 4x serial (2x RS232, 2x RS232/422/485 with voltage selection), 8-bit DIO header, 9-24V DC input
• Security: Onboard TPM 2.0
• Operating temperature: 0°C to 60°C

Why it matters

The explicit Ubuntu 24.04 support distinguishes this from typical Windows-only industrial boards, though BIOSTAR currently only publishes Windows drivers. The three dedicated M.2 slots (B-key for cellular, E-key for Wi-Fi, M-key for storage) reduce the expansion conflicts common on compact industrial SBCs.
