SENORTECH motherboard for bssh11

Embedded system integrators and industrial automation engineers often need a compact, reliable mainboard that can drive kiosks, thin clients, or digital signage without a dedicated GPU. The SENORTECH MK-BKE1ASTA0 steps into that role: a Mini-ITX board built around the Intel Celeron J1900 quad-core SoC, offering a fanless-friendly 10 W TDP and a rich set of legacy and modern I/O. It is the direct replacement board for the bssh11 system, so drop-in upgrades or repairs are straightforward.

Key specifications

• Form factor: Mini-ITX (170 × 170 mm)
• CPU: Onboard Intel Celeron J1900 (4 cores, 2.0 GHz burst, 10 W TDP)
• Memory: 1× DDR3L SO-DIMM slot, up to 8 GB
• Storage: 1× SATA III, 1× mSATA
• Video outputs: 1× HDMI, 1× VGA
• Network: 2× Gigabit Ethernet (Intel I211AT)
• USB: 2× USB 3.0, 4× USB 2.0 (2 rear, 2 via header)
• Serial: 2× RS-232 COM ports
• Expansion: 1× full-size Mini PCIe
• Audio: Realtek ALC662 HD Audio
• Power: DC 12 V input
• Operating temperature: -10 °C to 60 °C

Why choose it

The J1900's low power draw means the board can run in sealed, fanless enclosures, reducing dust ingress and maintenance. Dual Intel Gigabit LAN ports make it suitable for firewall, router, or network appliance builds, while the legacy VGA and RS-232 ports keep it compatible with older industrial displays and peripherals. The mSATA slot allows a compact SSD, and the Mini PCIe slot can host a Wi-Fi card or other expansion module.

Ideal use cases

• Industrial control and automation PCs
• Digital signage and kiosk systems
• Network appliances (pfSense, OPNsense, etc.)
• Thin clients and point-of-sale terminals
• Repair or upgrade of bssh11-based systems

Good to know

The board uses a standard 12 V DC input, so a suitable power supply is required (not included). It supports Windows and Linux operating systems. The AMI UEFI BIOS includes a programmable watchdog timer (1–255 seconds/minutes) for unattended operation. Always verify chassis clearance and cooling when installing in compact enclosures.
