ALF51: Intel Atom / Pentium/ Celeron 1.8inch SBC


ALF51: Intel Atom / Pentium/ Celeron 1.8inch SBC


ALF51 is a 1.8” SBC based on the Intel Atom® Processor E3900 Series, ideal for many space-critical and thermally demanding applications, including robotics, industrial automation and medical devices.

As small as a credit card (84 x 55 mm), the ALF51 is designed with 30% extended process capability and low power consumption of an average of 9W TDP thus providing energy efficiency. Thanks to the fanless design and its industrial-grade features that support extended temperature range of up to -40 to 85°C and 12VDC, the ALF51 SBC provides reliable performance even under harsh conditions whilst ensuring long-term service life up to 15 years.

The ALF51 SBC is fully equipped with various I/O ports such as 2 Intel GbE, 1 COM, 2 USB 3.1 Gen 1 and 1 USB 2.0. The ALF51 is especially designed as an IoT gateway with dual GbE, where one GbE can be connected to the network server and the other GbE to the respective device, e.g. an I/O controller or a camera that receives and transmits data. It also supports the Mini-PCIe expansion for WIFI / BT and 3G/4G in IoT solutions
