Today, Boingfire Systems unveils the BFT4KB, a purpose-built network appliance that combines Intel Atom architecture with enterprise-grade connectivity in a turnkey, fanless design.
Built on Intel Atom Architecture
The BFT4KB is powered by the Intel® Atom™ x5-E3940 quad-core processor, running at a base frequency of 1.6 GHz with a burst capability of 1.8 GHz. This efficient architecture delivers balanced performance and power consumption, making it particularly well-suited for always-on network infrastructure where energy efficiency matters. Paired with 4 GB of onboard DDR4 memory and housed in a compact black anodized aluminum BFCASET4S enclosure (189 × 157 × 29 mm), the BFT4KB is engineered for reliable, continuous operation.
Core Capabilities
2.5 GbE Connectivity: Four Intel I226-V 2.5 Gigabit Ethernet ports deliver the throughput required for modern networks, providing 2.5× the bandwidth of standard gigabit connections without the complexity of 10GbE infrastructure.
Versatile Expansion Architecture: The BFT4KB features four mini-PCIe slots and one M.2 B-key slot, enabling diverse expansion configurations—from dual-band Wi-Fi and multi-carrier LTE/5G connectivity to specialized network interface cards. Four integrated SIM slots support complex multi-carrier deployment scenarios.
Dual mSATA Storage: Two full-size mSATA slots with SATA 3.0 interfaces provide fast, reliable solid-state storage and support software RAID for data redundancy and performance optimization.
Comprehensive I/O: Access your system through multiple interfaces, including Micro-HDMI (4K @ 60Hz), USB 3.0, USB 2.0, a serial console via RJ45 and TTL headers, and 24 GPIO pins for custom integrations and external device control.
Fanless & Rugged: With a fanless thermal design and an operating temperature range from 0°C to 60°C, the BFT4KB operates silently while withstanding challenging environmental conditions. The programmable watchdog timer and optional TPM 2.0 module add layers of reliability and security.
