DFI ALF51-BN-26N50 Intel Celeron N3350 (Apollo Lake) Femto-ITX Single Board Computer with Dual GbE and 2GB LPDDR4 Memory

Kiosks, thin clients and self-service terminals tend to spend their time on one interactive application, where a quick response to a tap matters more than parallel threads. The ALF51-BN-26N50 is a 1.8″ Femto-ITX single board computer in the DFI ALF51 series that uses the Intel Celeron N3350 for that kind of indoor terminal, on an 84 x 55 mm board that fits behind a display.

The Celeron N3350 is a dual-core Apollo Lake processor at 1.1 GHz with a burst clock of 2.4 GHz, the highest in the series, and a 6 W TDP. It has 2 GB of single-channel LPDDR4 at 2400 MHz soldered down and 64 GB of eMMC for the operating system and application. Intel HD Graphics drives a DP++ output at up to 4096 x 2160 at 60 Hz. DFI lists Windows 10 IoT Enterprise 64-bit and Linux support with UEFI boot, and the board has a firmware TPM 2.0 and a watchdog timer.

Two GbE ports on Intel I210 controllers connect the terminal to the network, with a second port free for a local device. Two USB 3.1 Gen 1 Type-A ports and a USB 2.0 header serve a touch controller, card reader or printer, and one RS-232/422/485 header links a payment terminal or older peripheral. An 8-bit DIO header and a full-size mini PCIe socket for Wi-Fi complete the I/O.

The ALF51-BN-26N50 runs from 12 V DC on a terminal block with a passive heatsink, from 0 to 60 °C, and carries CE, FCC and RoHS compliance. For four cores at 9.5 W, choose the ALF51-BN-26E40, or the ALF51-BN-26E30, whose Atom x5-E3930 is also offered in wide and extended temperature builds.
