Zeta miniature COM-based SBCs are interchangeable and scalable

Diamond Systems unveils the small COM-based Zeta single board computer (SBC) family.

Highlights include interchangeable COM Express COMs for scalability and long product life, a compact size, and levels of I/O, including an analogue and digital data acquisition sub-system.

Designed in the COM Express Mini Type 10 form factor (84 x 55mm / 3.3 x 2.2-inch), the Zeta family offers performance scalability due to its use of COM Express CPU modules.

Three processor options are currently available:   Intel Bay Trail E3825 dual core 1.33GHz CPU with soldered 2Gbyte RAM, Intel Apollo Lake E3940 quad core 1.60GHz CPU with soldered 4Gbyte RAM, Intel Apollo Lake N4200 quad core 1.1GHz (burstable to 2.5GHz) CPU with soldered 8Gbyte RAM.

The use of interchangeable CPU modules in the popular COM Express Mini Type 10 format enables Zeta to serve applications across a spectrum of price and performance needs, says Diamond Systems. The Zeta family also offers a long product lifetime by simplifying migration to a new CPU when the current one reaches its end-of-life.

Zeta is particularly suitable for applications with expected lifetimes of 10 or more years, including military, medical, and transportation. Zeta’s two-board COM + baseboard construction yields the highest feature density possible in a given footprint. The COM provides the core CPU functions, while the baseboard provides system I/O plus the data acquisition subsystem, power supplies, and expansion sockets. Zeta provides as much as a 60 per cent reduction in size compared to boards in larger form factors offering the same level of I/O.

Zeta’s I/O list includes VGA display and single channel LVDS port, dual Gigabit Ethernet, four USB 2.0 ports and one USB 3.0 port, four RS-232/422/485 ports with software-programmable protocol and termination, 16 digital I/O lines, optional complete analogue and digital data acquisition system, integrated wide-range six to 36V power input circuit Zeta is available in two I/O configurations, digital I/O only or digital + analogue I/O. The DIO-only circuit offers 16 DIO lines with selectable 3.3V/5.0V logic levels. The full circuit includes 16 channels of 16-bit A/D, four channels of 16-bit D/A, 27 digital I/O lines with selectable 3.3V/5.0V logic levels, and eight 32-bit counter/timers, all supported by Diamond’s free, Universal Driver data acquisition programming library. An interactive graphical control panel for Windows and Linux is also provided to control all data acquisition features. Zeta offers multiple options for system expansion and mass storage. It includes a PCIe Minicard / mSATA socket and a micro-SD socket. An expansion connector enables the installation of a daughterboard that contains an M.2 SATA SSD socket, a second PCIe Minicard socket, HD audio, and 16 additional GPIO lines. Zeta’s built-in heat spreader efficiently removes heat from the SBC to keep the processor and all internal electronics cooler for improved reliability. The bottom-side mounting configuration of the heat spreader provides a secure and convenient mounting system for the board. It also simplifies the installation of I/O expansion modules by eliminating interference or airflow problems that can occur with traditional heat sinks. All three models of Zeta are tested for operation over the full industrial temperature range of -40 to +85 degree C, for vehicle applications. 

Six models are currently offered, based on various combinations of CPU and baseboard.

Complete development kits consisting of the selected CPU, a flashdisk with either Windows 10 or Linux OS installed, and a cable kit are available to accelerate the development effort.
