Sintrones SBOX-2625-SF Intel N150 Compact Embedded Computers with Dual 2.5GbE and Serial or Digital I/O Options

A lot of edge computing happens in small cabinets and behind counters, where the job is steady and modest: run a kiosk, drive a menu board, log a machine, gather data from a few serial devices. The Sintrones SBOX-2625-SF series is a family of compact embedded computers for that work, in a steel case of 182 x 106 x 40 mm weighing 720.5 g. Sintrones rates the SBOX-2625-SF series from -30 °C to 60 °C with 0.6 m/s airflow, tested with the unit mounted on an aluminum heat spreader to simulate cabinet conditions.

Every model uses the Intel Processor N150, a four-core Twin Lake part running up to 3.6 GHz, with Intel Graphics and one DDR5-4800 SO-DIMM socket for up to 16 GB. Two HDMI 2.0b ports drive up to 3840 x 2160 at 60 Hz, and networking is two Intel I226-LM 2.5GbE ports, which can keep a device network separate from the uplink. TPM 2.0 and a watchdog are standard. An M.2 Key B combo socket with SIM support takes an optional 5G or LTE module or an M.2 2242 SATA SSD, an M.2 Key E socket takes optional Wi-Fi, and a 2.5″ SATA SSD holds the operating system, with Windows 11 IoT Enterprise LTSC or Ubuntu 24.04 LTS listed.

The three builds differ at the rear panel. The SBOX-2625-SF has two RS-232/422/485 ports and six USB ports, two USB 3.2 Gen 1 and four USB 2.0, for retail set-ups with scanners and printers. The SBOX-2625-SF-2S trades two of the USB 2.0 ports for four digital inputs (5 to 36 V DC) and four digital outputs, for sensors, indicators and relays. The SBOX-2625-SF-3S adds a third serial port, an RS-232, in place of the digital I/O, for point-of-sale and line-side devices that still use serial.

In practice, the SBOX-2625-SF series suits kiosks, digital signage players, point-of-sale systems and small automation cabinets. Power is 9 to 36 V DC on a two-pin terminal block with over-current, over-voltage, surge and reverse polarity protection, which suits 12 V and 24 V supplies, and every model lists CE, FCC Class A, UKCA and IEC/EN 62368-1. Each model wall-mounts, with four antenna holes for the optional wireless modules and line-out and mic-in audio for kiosk prompts.
