Airborne Modular Computer (PCIe/104)

F1-30 banner


Introduction of ATR

ATR (Air Transport Rack) is a standard that specifies form fit and function of enclosures designed to protect the main internal system. This military enclosure must meet EMI / EMC requirements to prevent noise interference, provide lightning protection and be isolated from small particle contaminants. So, it can be deployed in unmanned aerial vehicles, fighters, and helicopters. To satisfy diverse conditions, ATR chassis are available in different sizes—1/2, 3/4 and Full ATR sizes. Based on 3/4 ATR size, 7StarLake launches a new Rugged Airborne Mission Computer F1-30.

As a modular mission computer, F1-30 has mechanical feature for mounting in horizontal orientation, offering open architecture to maximize use of interoperability. For example, together with PCIe104 expansion connectors, F1-30 is able to build a stackable architecture, which can be integrated with PCIe/104 expansion modules depending on customers’need, hence it's highly configurable to specific requirements. Founded on such an open structure, It is an optimum choice for mission computing, demanding graphics generation applications, and GPU-accelerated data processing.

Integrated Features List

I. Frame grabber card (Analog to Digital / PAL )

Frame grabbers may be used in military applications. For instance, when a potential breach of abnormal signal is detected, a frame grabber captures an image or a sequence of images in digital form, and then transmits the data to pilots or command control center. By adding frame grabber card, F1-30 can collect useful images and help pilots to react promptly on the ever-changing battlefield.

CAN bus

Mini PCIe GNSS Card

F1-30 series has been integrated with multi vendor’s CAN Bus module, such as PEAK – a leading provider of hardware, software, and services for automotive and industrial communication.

Nowadays, the modern aircraft may have many electronic control units (ECU) for various subsystems, and a subsystem may need to receive feedback from sensors. The CAN standard was devised to fill this need. Combining with CAN Bus, F1-30 can establish interconnection between different systems, and collate various sensor inputs from around aircraft without a network host.


III. Multi-I/O expansion card

SK401 is a PCIe/104 (StackPC) peripheral module designed for different stacking criteria. For example, it can expand storage by supporting either with two mSATA modules or one mSATA with one 2.5” SSD which can be stacked with other StackPC modules. Based on mini-PCIe, SK401 also supports further I/O modules’ expansion, such as LAN module offering 4 LAN port, which makes receiving data from sensors over Ethernet become possible.





IV. NVIDIA MXM carrier card

SK220 is a PCIe/104(StackPC) carrier module supporting most MXM graphic cards from NVIDIA and AMD. By using SK220 our customers can upgrade graphic card easily to respond well in the ever-developing world. Plus, SK220 possess the flexibility of switching the signals between FPE connector (PCIe x16), StackPC (PCIe x1, x4) via dip switch. Thus, it is a best solution for multi-display  demanding applications like control cab and command center.




MIL-STD-461/1275/704 150W DC-DC Power Module

Durable metal casing with an isolated MIL-STD-461, MIL-STD-1275, MIL-STD 704 and DO-160 compliant power module SK710 that protects against aircraft voltage surges, spikes and transients is well suited for the strictest military requirement and deliver optimal performance in harsh conditions. Thanks to SK710, F1-30 is suitable for outdoor airborne applications. What’s more, SK710 is a MIL-COTS power system. Thus, our customers can deploy F1-30 immediately to get a head start on the frontline




Advanced Conduction Cooling


Flexibility in Nature – Configurative Thermal Design

Complex cooling solutions are often required to meet the high power requirements of multiple boards within a chassis. Starlake’s ATR solution comes with an all-in-one design enclosure; each slot can securely fit a Wedge-Lok, and each layer comes with a firmly attached, directly touched copper heat plate to complete an effectively cooled interior. What makes conduction cooling method so practical is that it is without moving parts, therefore suitable for high altitude and underwater applications.



With 5 segments, shifted design, Wedge-Lok also help to transfer the heat and ensure best conductivity of heat load. The multi-segment design highlights on its ability to withstand massive vibration and shock, providing even higher sustainability through the torque-limiting design.

Rugged Connectors


MIL-DTL-38999 Connectors

7StarLake also provides MIL-DTL-38999 Connectors as an enhanced alternative choice compared with M12. MIL-DTL-38999 is a high-performance cylindrical connector family designed to withstand the extreme shock, exposure and vibration that are commonplace in Defense and aerospace applications. D38999 connectors are lightweight and can stand up to environmental challenges. Made with removable crimp or fixed hermetic solder contacts, these connectors provide high-vibration characteristics and are suitable for severe wind and moisture problem areas. Equipped with MIL-DTL-38999 connectors, F1-30 is undoubtedly durable and ruggedized enough despite operating in the harsh environment.


M12 Connectors

F1-30’s top side, which is designated as the customized I/O interface, is equipped with water/dust proof MIL-STD M12 connectors. All IP67 interfaces can be closed tightly using the screw plugs and sealing caps in sizing M12. The holding bands are fastened on the cable or the hosing and are thus held captive. The M12 metal protective cap with fixing chain is suitable for all pin versions. It is used in harsh industrial environments or for EMC applications.
