Versalogic’s “BayCat” is a rugged PC/104-Plus SBC with an Atom E3800 SoC, numerous I/O ports, ISA, PCI, and miniPCIe expansion, and -40 to 85°C operation.
The BayCat is basically a re-spin of VersaLogic’s Bengal single-board computer from 2014, with legacy ISA expansion substituted for the Bengal’s PCIe expansion. The BayCat conforms to the traditional PC/104-Plus spec’s format, which combines stackable ISA (104-pin) along with stackable PCI (40-pin) expansion. The Bengal’s nascent “PCIe/104 OneBank” format, which does not appear to have garnered much industry support, implemented a combination of stackable PCIe and stackable PCI expansion.
Like the Bengal, the BayCat is promoted as a legacy replacement for PC/104 customers looking to move up to an Intel Atom E3800 Bay Trail SoC. Once again, you can choose from single, dual, and quad-core options.
The rugged BayCat “enables the next generation of intelligent medical, military, and industrial systems to be smaller, lighter, and more energy efficient,” says VersaLogic. Applications are said to include in-vehicle communications, complex medical devices, industrial control and automation, mobile autonomous systems, and other embedded devices.

Compared to the Bengal, the BayCat adds a microSD slot, and instead of 16x GPIOs, it provides 24x 3.3V DIO lines. Other than the differing PC/104 interfaces, it appears to be otherwise identical, right down to the Linux support and 4.2 x 3.8 inch dimensions. You can load up to 8GB RAM, and store data with SATA 2 and mSATA interfaces, the latter coming via a general-purpose mini-PCIe slot.

VGA and dual mini-DisplayPorts are available for displays, and additional connectivity includes dual Gigabit Ethernet ports, one USB 3.0 port, and four USB 2.0 ports. There are also two RS-232/422/485 ports, and an SPI/SPX expansion interface among other I/O.
The BayCat supports plus -40 to 85°C temperatures, and offers shock and vibration resistance per MIL-STD-202G. A TPM module is available, along with a heatspreader and optional heatsinks, fans, and other add-ons, including customization services.
