SKU: BFN5 Category:

The BFN5 system board by Boingfire is a compact, yet powerful, platform designed for a variety of embedded applications. It features the Intel Atom E3845 processor with four cores, operating at 1.91 GHz, and includes 2 MB of L2 cache and AES-NI, TPM2.0 for enhanced security and performance. The board supports DDR3L memory at 1333MHz with a maximum capacity of 8 GB through a single 204-pin SODIMM socket.

For display outputs, it offers an HDMI port supporting resolutions up to 2560×1600 at 60 Hz, catering to high-definition content. Networking is robust with up to three RJ45 Ethernet ports powered by the Intel I211 Gigabit controller, ensuring fast and reliable data transmission.

Storage options are versatile, including one full-size mSATA slot, an eMMC slot supporting eMMC modules, and a SATAII interface for additional storage expansion. The board’s internal I/O includes three serial ports, HDMI, reset and power buttons, four USB ports (three USB2.0 and one USB3.0), and 24-bit GPIOs for a wide range of connectivity and expansion possibilities.

Expansion is further enhanced with three MINI_PCIE slots designated for 4G/LTE, WiFi modules, enabling various communication capabilities in embedded systems. The board operates efficiently with a low power input of 12V ±10%, with typical power consumption as low as 5.28W and a maximum consumption of around 12W under full load, making it an energy-efficient solution for sustained operations.

Designed to operate in a broad range of temperatures from 0 to 60°C and withstand non-operating conditions from -40°C up to 85°C, the BFN5 ensures reliability in challenging environments. Its compact dimensions (160 x 152 mm) and a total height of 33mm with the cooler, PCB, and bottom included, along with a lightweight profile (0.45 kg with heatsink), make it an ideal choice for applications where space and power efficiency are critical.

The BFN5 by Boingfire is a versatile, durable, and energy-efficient system board, suitable for a wide range of embedded computing applications, from industrial automation to digital signage and beyond.
