In the fields of industrial automation, military measurement and control, and medical imaging, full-length system motherboards (SHBs) based on PICMG 1.3 specifications remain the preferred computing platform for many critical task applications due to their standardized external dimensions, rich I/O expansion capabilities, and long-term supply commitments. ADLINK NuPRO-E330 is an industrial grade SHB that supports LGA1156 packaged Intel Core i7/i5/i3 and Pentium processors. Paired with the Intel Q57 Express chipset, it offers up to 8GB of DDR3 memory, 6 serial ports (including 1 multi protocol configurable port), 9 USB 2.0 ports, 6 SATA interfaces (supporting RAID 0/1/5/10), and integrates Intel Active Management Technology (AMT) 6.0 and PCIe 2.0 bus. This board is particularly suitable for industrial control and data acquisition systems that require multi serial communication, data storage redundancy, and remote management capabilities. It is also an ideal upgrade path to replace early LGA775 or 945G chipset motherboards. This article will provide engineers with a complete technical reference from the aspects of hardware specifications, interface layout, expansion options, compatibility, and deployment considerations.
Product positioning and target applications
The NuPRO-E330 follows the PICMG 1.3 full-length dimension specification (338mm × 126mm) and can be combined with corresponding backplates (such as the NuPRO series backplate) to achieve multiple expansion card combinations. It is positioned as a mid to high end industrial computing platform, suitable for:
Production line automation control: Connect PLC, barcode scanner, sensor, and HMI equipment through multiple serial ports;
Data acquisition and monitoring (SCADA): using RAID storage to ensure the security of historical data, and implementing remote out of band management through AMT;
Medical image processing: compatible with PCIe x16 discrete graphics card or mPCle-8770 graphics card, supporting high-resolution display;
Military/vehicle mounted computing: wide temperature design (working from 0~60 ℃), meeting the requirements of general industrial environments.
Compared to the previous generation LGA775 platform, NuPRO-E330 offers higher computing performance (supporting quad core eight threading), faster I/O bandwidth (PCIe 2.0), and lower power consumption (32nm process processor).
Detailed explanation of compatibility between processors and chipsets
The board supports LGA1156 socket and is compatible with the following processor series (please note TDP and heat sink matching):
Intel Core i7-860: 2.80GHz, 8MB cache, 4-core 8-thread, 45nm, TDP 95W (without built-in graphics card);
Intel Core i5-750:2.66GHz, 8MB cache, 4-core 4-thread, 45nm, TDP 95W (without built-in graphics card);
Intel Core i5-660: 3.33GHz, 4MB cache, 2-core 4-thread, 32nm, TDP 73W (built-in graphics card);
Intel Core i3-540: 3.06GHz, 4MB cache, 2-core 4-thread, 32nm, TDP 73W (built-in graphics card);
Intel Pentium G6950: 2.80GHz, 3MB cache, 2 cores and 2 threads, 32nm, TDP 73W (built-in graphics card).
Selection suggestion:
If high parallel computing capability is required (such as multi-channel video encoding), choose i7-860/i5-750;
If integrated display output is needed to save expansion slots, choose i5-660/i3-540 or G6950;
Please note that the i7-860 and i5-750 do not come with built-in graphics and require an external graphics card (PCIe x16 or mPCle-8770) to light up the monitor.
The chipset is Intel Q57 Express, supporting PCI Express 2.0 (twice the bandwidth of 1.0), providing 6 SATA 3Gb/s ports, and supporting Intel Matrix Storage Technology (RAID 0/1/5/10), suitable for building data redundancy systems. In addition, Q57 supports Intel AMT 6.0 (with specific 82578DM network port), which can achieve remote power management, keyboard/mouse redirection, and system event logging, greatly improving maintenance efficiency.
Memory and Storage Configuration
Memory: 2 240 pin DIMM slots, supporting dual channel DDR3 1066/1333 MHz, with a maximum capacity of 8GB (it is recommended to use 2 × 4GB or 2 × 2GB non ECC, unbuffered memory modules). ECC is usually not required in industrial applications, but if high data reliability is required, industrial grade wide temperature memory can be chosen.
SATA storage: 6 SATA 3Gb/s interfaces, of which 4 are on-board standard 7pin connectors, and the other 2 are led out through the backplane (can be used for hot swappable hard drive enclosures). Supports RAID 0/1/5/10, suitable for building mirrored or parity checked arrays. Note that if using RAID 5, it is necessary to use Intel Rapid Storage Technology drivers and enable the corresponding options in the BIOS.
Additional storage: onboard a Floppy interface (although gradually phased out, some older devices still require floppy drive firmware updates), and an LPT parallel port (via backplane or cable).
Rich peripheral I/O interfaces
4.1 Serial Communication (6 × COM)
This is the outstanding advantage of NuPRO-E330, which provides 6 serial ports:
COM1~COM5: Standard RS-232, supports full duplex communication, suitable for traditional serial devices;
COM6: Multi protocol configurable, supports RS-232, RS-422, RS-485, and RS-485+(with automatic direction control or enhanced driver), and selects the working mode through jumper or BIOS settings. This port is particularly suitable for connecting remote sensors, frequency converters, or smart meters, and can directly achieve differential communication without the need for additional converters.
All serial ports are led out from the onboard 10 pin pin pin through the matching COM port cable (with bracket), and a dual port cable is randomly attached for easy installation on the front panel of the chassis.
4.2 USB and Keyboard/Mouse
9 USB 2.0 ports: One is located on the panel (standard Type A), four are led out through onboard pins (cable required), and the other four are provided through the backplane (USB signal defined by PICMG 1.3). Supports multiple USB devices, such as keyboards, mice, USB drives, cameras, etc.
PS/2 interface: 1 Mini DIN socket, capable of simultaneously connecting keyboard and mouse (via Y-shaped cable), suitable for pure industrial environments that do not require USB.
4.3 Parallel ports and floppy drives
The parallel port (LPT) supports SPP/ECP/EPP mode and can be used to connect parallel port printers or old-fashioned EPROM programmers.
The floppy drive interface (FDD) supports 1.44MB/2.88MB floppy drives, making it easy to upgrade old system firmware.
4.4 Audio
The onboard High Definition Audio pin head (HDA) needs to be connected to a DB-Audio2 motherboard (optional) to provide Mic in, Line in, and Line out interfaces, suitable for situations that require voice alarms or recording.

Display and Expansion Slot
5.1 Display Output
Integrated graphics card: Only available when using processors with built-in GPUs (i5-660, i3-540, G6950), output signals are achieved through onboard PCIe Mini Card slots or external PCIe x16 graphics cards? ——Original text description: The integrated graphics card signal needs to be output through the PCI Express x16 or onboard PCI Express Mini Card slot (for optional mPCle-8770 graphics card), which means that the card itself does not have a direct VGA/DVI/HDMI interface and must be converted through an expansion card or daughter card. Users should note that if using a CPU (i7-860/i5-750) without an integrated graphics card, a dedicated graphics card (such as a standard PCIe x16 graphics card or mPCle-8770) must be installed.
Independent graphics card: Provides PCI Express x16 slots, supports full height graphics cards, and can drive multiple displays or high-performance graphics applications (such as machine vision). At the same time, there is a PCIe Mini Card slot on the board that can accommodate the mPCle-8770 (2D VGA display card) as a low-cost display solution, saving x16 slots for other high-speed devices.
5.2 Expansion Slot
As a PICMG 1.3 system motherboard, its PCIe and PCI resources are expanded through the backplane. The NuPRO-E330 itself provides a PCIe x16 and a PCIe Mini Card, while the remaining PCIe and traditional PCI signals are transmitted to the expansion slots on the backplane through backplane connectors (P1/P2), depending on the backplane design (such as a 14 slot backplane that can expand up to 7 PCIe and 6 PCI devices).
Network and Remote Management
Onboard dual network card:
Intel 82578DM Gigabit Ethernet PHY: Supports Intel Active Management Technology (AMT) 6.0 and provides hardware based remote management features such as remote boot, BIOS updates, and operating system recovery, which can be accessed through the management console even when the system is not running. This feature requires cooperation with Intel management engine drivers and AMT configuration software.
Intel 82574L Gigabit Ethernet Controller: an independent PCIe x1 controller that supports Wake on LAN (WOL) and can be used as a regular data network interface, as well as forming dual network redundancy or load balancing with 82578DM.
If AMT needs to be enabled, the relevant options need to be enabled in the BIOS and ensure that it is connected to a switch or router that supports AMT.
Mechanical, environmental, and power characteristics
Appearance: Full length PICMG 1.3 (338mm × 126mm), height compatible with standard 4U industrial control chassis.
Working temperature: 0~60 ℃, storage -20~80 ℃, humidity 10%~90%, no condensation.
Power consumption: Depending on the CPU model, the maximum TDP is 95W (i7-860/i5-750), and it is recommended to use a matching 1U/2U/3U heat sink (corresponding models are included in the random selection list). Note that the 95W processor may require forced air cooling inside a sealed chassis.

Typical upgrade and replacement scenarios
Many existing systems are based on older LGA775 platforms (such as Intel Q965/G31 chipset) or AMD platform PICMG 1.3 motherboards, facing issues such as insufficient performance, few peripheral interfaces, and inability to support new operating systems (such as Windows 7/10 64 bit). NuPRO-E330 offers the following significant improvements:
Performance improvement: From dual core to quad core/hyper threading, doubling the performance of integer/floating-point operations;
Memory bandwidth: DDR3 1333 has increased bandwidth by about 60% compared to DDR2 800;
Storage acceleration: Supports RAID to improve data reliability and read/write speed;
Remote management: AMT can significantly reduce on-site maintenance time;
Multiple serial ports: 6 native serial ports to avoid additional expansion cards occupying the slot.
When replacing, attention should be paid to the compatibility of the chassis heat sink (check if the CPU heat sink height matches the chassis limit), whether the backplane supports PICMG 1.3 definition (at least+12V CPU power supply is required, PICMG 1.3 specification requires the backplane to provide additional 12V power supply capability), and whether the operating system drivers are complete (NuPRO-E330 supports Windows XP/7, Server 2008, and mainstream Linux distributions).
Deployment precautions and common issues
CPU heat sink selection: It is necessary to choose the corresponding 1U/2U/3U heat sink according to the height of the chassis. Passive heat sinks cannot meet the 95W TDP and must be paired with fans.
Memory compatibility: Use well-known brand DDR3 1333/1066 non ECC memory, it is recommended to plug in two to activate dual channel mode. If different specifications are mixed, the system will automatically slow down.
BIOS settings: If using an integrated graphics card, shared video memory needs to be allocated in the BIOS (default may be 32MB, can be adjusted to 256MB as needed); If using a dedicated graphics card, ensure that the PCIe initial display settings are correct.
RAID configuration: Set the SATA mode to RAID in the BIOS, press Ctrl+I to enter the Intel RAID configuration interface when booting up, create the array, and then install the operating system (RAID drivers need to be loaded in advance).
Serial port mode switching: Multi protocol switching of COM6 is usually achieved through jumper caps (located near the COM6 pins on the board). Please refer to the jumper table in the manual for details to avoid communication abnormalities caused by mistakenly setting it to high voltage.
AMT activation: The first activation requires entering the ME configuration interface of BIOS, setting management passwords and network parameters, and installing Intel Management Engine interface drivers in the operating system.
Power requirements: It is necessary to ensure that the+12V output capability of the chassis power supply is sufficient (especially when using a 95W CPU), and the PICMG 1.3 backplane needs to provide additional+12V current through the P2 connector.
If encountering startup failure or instability, first check if the CPU cooling fan is running, if the memory is securely plugged in, and clear the CMOS to restore default settings.
Software Support and Lifecycle
The driver of NuPRO-E330 supports Windows XP (32/64), Vista, 7 (32/64), Server 2008, as well as mainstream Linux (Fedora 10, RHEL 5). For Windows 10, you can try using Windows 7 drivers, but it is recommended to first check the latest driver version on the ADLINK official website. As an industrial board, its product lifecycle usually lasts for 5-7 years, making it suitable for long-term projects.
