Jetway B903DMTX is a fanless industrial box PC built around the Intel N97 quad-core Alder Lake-N CPU and designed for industrial applications with up to ten USB Type-A ports, four DB9 serial ports, dual GbE, and support for M.2 wireless modules.

It supports up to 32GB of DDR5-4800 SO-DIMM memory, SATA III and M.2 SSD storage, along with WiFi and Bluetooth through an M.2 E-Key slot. The system also features 4Kp60-capable HDMI and DisplayPort video outputs. The embedded box PC runs on a 12–19V DC input, supports AT/ATX power modes, and includes features such as a watchdog timer, Intel PTT (fTPM), and a wide -10°C to 60°C operating temperature. These features make it suitable for factory automation, kiosks, digital signage, industrial gateways, and edge computing systems.

The Jetway B903DMTX typically ships with a 12V/5A (60W) power adapter, power cord, and two external 2.4/5GHz Wi-Fi antennas, along with basic mounting and grounding hardware. On the software side, the system supports Windows 10 (64-bit), Windows 11 (64-bit), and Linux. Since the consumer variants of Windows 10 are not supported anymore, this likely means Windows 10/11 IoT Enterprise LTSC 2021, or a similar Windows version with long-term support.

Usually, Jetway introduces multiple SKUs for different use cases, but for the B903DMTX, it comes with a single commercial SKU listed as HBJC903MTX-9700-N, which includes the Intel Processor N97 and the standard I/O configuration. Jetway also supports project-based customization, including an optional M.2 M-Key 2242 SATA interface (by request).

The list of Intel N97-based industrial fanless systems continues to grow, and the B903DMTX adds to products such as the BIOSTAR MT-N97 mini PC, which features a wide 9V-24V DC input, support for M.2 wireless and 4G/5G cellular modules, the AEEON UP Squared 7100 embedded system with a screwable DC input jack, dual Ethernet, and dual COM ports (RS232/RS485), and even Jetway’s own B420UADN1 Intel N97 fanless mini PC for kiosks and digital signage applications, among many others.

As always, Jetway does not provide public pricing and availability information. More details, including a user manual, can be found on the product page. The company usually provides the BIOS along with Windows/Linux drivers, but at the time of writing, I cannot find those in the download section.
