Industrial Mini-ITX board with fanless 2GHz (2.7GHz Burst) Intel Quad Core J4125 Gemini Lake processor and integrated Intel UHD Graphics 600. VGA, HDMI, LVDS and eDP, 2x Gigabit Ethernet Ports, 64GB DDR4 SODIMM memory support, M.2 SATA and 5x SATA storage (4 with Integrated Marvell 88SE9230 RAID), M.2 Type E CNVi Slot, PCIe x4 Slot and up to 6 COM ports.

Rear Panel Connectors: 12V regulated DC Input, 2x RS232/422/485 DB9 Serial Ports; VGA Port (up to 1920x1080 @ 60Hz); HDMI Port (up to 3840x2160 @ 60Hz); 2x Realtek RTL8111HS RJ45 Gigabit Ethernet Ports; 2x Type-A USB 2.0 Ports; 2x Type-A USB 3.0 Gen1 Ports; 3.5mm Line-Out, Mic and Line-In Ports.

Power Connectors: 1x 4pin 12V alternate power connector (must not be used at the same time as the external DC input); 1x AT/ATX Power Mode Jumper.

Expansion: 1x M.2 2230 Type-E socket (for CNVi Wi-Fi/Bluetooth cards); 1x PCIe x4 (Gen2 x 2) Expansion Slot.

Storage Connectors: 5x 6Gbps SATA Ports (4 support RAID-on-motherboard 0/1/10 through Marvell 88SE9230 host controllers, 1 supports SATA DOM); 3x SATA Power Out (2 cables included, each supports 2 drives); 1x M.2 2242/2260/2280 Type-M Socket (underside of board, supports SATA M.2 drives).

Graphics Headers: 1x LVDS Header (up to 1920x1280 @ 60Hz), 1x eDP Header (up to 1920x1280 @ 60Hz). VGA and HDMI connectors on the rear of the board. 3 independent graphics outputs supported.

Serial and USB Headers: 4x RS232 Headers (2mm pitch); 2x USB 3.0 Gen1 headers on one connector; 2x USB 2.0 headers.

Fan Headers: 1x 4-pin CPU Fan Header; 1x 4-pin Chassis Fan Header.

Additional Board Headers: Audio Header; Backlight Control Header; Buzzer; Chassis Intrusion Header; Clear CMOS Jumper; GPIO Header; 2x LAN LED Connectors; RAID LED Header; 3x SATA Power Out Headers; SMBUS Header; 2W Speaker Header; System Front Panel Header; 14-pin TPM Module Connector.

12V DC Power input: The mITX-4125A requires a 12V AC Adapter to power the board and feed power to any SATA devices through 3 on-board 4pin power output connectors (2 cables included). There is an alternate 12V input on a 4pin Molex 5566 connector which can also be used (though not at the same time as the rear input). We sell several enclosures without power supplies, or you can bypass the PSU on any other compatible Mini-ITX case.

Powering from an ATX PSU: To power using an ATX PSU, an ATX Bridging Plug can be connected to the ATX connector of the PSU, and the 12V P4 plug (Black/Yellow cables) connected to the motherboard. Use the AT/ATX Mode jumper to control power up behaviour (AT Mode = power on immediately, ATX Mode = power when power switch pressed).

Suitable cases: The following enclosures come without an internal PSU and are compatible with the mITX-4125A: M350 and M5X**. Other Mini-ITX Chassis can be used with the mITX-4125A if their PSU is bypassed and a 60W minimum 12V external AC Adapter is used.

Memory: The mITX-4125A supports up to 64GB DDR4 memory on 2x up to 32GB DDR4 SODIMMs, running at 2400MHz.

Packaging: The mITX-4125A is an industrial board sold only in multi-packs. We have individually repackaged each board in recycled Mini-ITX board boxes.

Box contents: Motherboard, 2x SATA Power Cables (each cable can power 2 devices), Standard I/O Shield. If connecting a SATA device you will require a SATA data cable.
