Sintrones SBOX-2625-SF-3S Intel Processor N150 Compact Embedded Computer with 3x COM and Dual 2.5GbE

Point-of-sale and line-side systems still lean on RS-232: receipt printers, weighing scales, barcode readers and payment terminals without a network port. The Sintrones SBOX-2625-SF-3S gives them three serial ports on a compact embedded computer, two RS-232/422/485 and one RS-232, with dual 2.5GbE for the network side. It is the three-COM build of the SBOX-2625-SF series, and it trades the digital I/O of its sibling for that extra port.

Its Intel Processor N150 has four Twin Lake cores running up to 3.6 GHz and Intel Graphics, with one DDR5-4800 SO-DIMM socket for up to 16 GB. TPM 2.0 and a watchdog with BIOS delay settings are included. Two HDMI 2.0b outputs reach 3840 x 2160 at 60 Hz, enough for a customer display and an operator screen, and Sintrones lists Windows 11 IoT Enterprise LTSC and Ubuntu 24.04 LTS.

Networking is two Intel I226-LM 2.5GbE ports. The SBOX-2625-SF-3S has two USB 3.2 Gen 1 and two USB 2.0 ports, line-out and mic-in, and no digital I/O. The M.2 3042/3052 Key B socket with SIM support is a combo slot for an optional 5G or LTE module or an M.2 2242 SATA SSD, the M.2 2230 Key E socket takes optional Wi-Fi and Bluetooth, and a 2.5″ SATA SSD holds the operating system. We supply it configured and tested, with memory, storage, the OS image and any wireless module fitted.

Input is 9 to 36 V DC on a two-pin terminal block, protected against over-current, over-voltage, surges and reverse polarity. The SBOX-2625-SF-3S operates from -30 °C to 60 °C with 0.6 m/s airflow, tested on an aluminium heat spreader to simulate a cabinet, and lists CE, FCC Class A, UKCA and IEC/EN 62368-1. The steel case wall-mounts and weighs 720.5 g. The SBOX-2625-SF-2S has digital I/O in place of the third port, and the SMB-2615 brings four COM ports to a 3.5″ SBC.
