Diamond Zeta Miniature COM-Based SBC

Complete Zeta SBC

Zeta Carrier Board top, with data acquisition

Description

The Zeta COM Express SBC family of ultra-small embedded computer boards combines a COM Express Mini CPU module mounted on a same-size carrier board to create a complete embedded PC. Designed in the COM Express Mini Type 10 form factor (84 x 55mm/ 3.3 x 2.2 in), Zeta provides an ultra-compact, industry-standard form factor solution.

3 key components pre-assembled:

		A Computer on Module (COM) providing the core CPU functionality
		A carrier board providing the I/O transceivers and connectors, power supplies, and expansion sockets
		A heat spreader with a flat exterior surface for direct mounting and heat transfer to the system enclosure

This layered architecture offers the highest functional density for any given footprint. As a comparison, Zeta offers functionality and performance equivalent to Diamond’s top-selling Aries SBC at just 40% of the size.

Zeta currently supports three processor options:

		Intel Bay Trail E3825 1.33GHz Dual Core CPU with 2GB RAM
		Apollo Lake E3940 1.6GHz quad core CPU with 4GB RAM
		Apollo Lake N4200 1.1GHz (burstable to 2.5GHz) Quad Core CPU with 8GB RAM

Zeta’s small size and high feature density make it an ideal choice for mobile applications. It stands ready to meet the challenges of these environments with a wide range 6-36VDC input voltage, a -40 to +85°C operating temperature range, and fanless heat spreader cooling (heat sink options are available).

Benefits of COM-based SBCs
The use of interchangeable industry-standard CPU modules on Zeta offers two important system designer benefits:

		Performance scalability: One can design multiple applications based on a consistent hardware platform and select the CPU that best fits the price / performance / power requirements of each one. In addition, as time goes on and your application needs more horsepower to support increased functionality, you can simply upgrade to a newer CPU with minimal to no redesign effort.
		Long product life: The majority of today’s x86 embedded processors offer limited lifecycles of 5-7 years, so any long-life product dependent on an x86 single-board computer (SBC) is likely to require redesign sometime during its lifecycle. Using industry-standard COMs lets you easily migrate to a new generation CPU module in the exact same form factor and containing the same feature set, with virtually no hardware or physical redesign efforts. Zeta is ideal for long-life applications such as Military, Medical, and Transportation.

Conduction Cooling

The bottom side heat spreader on Zeta provides the most efficient cooling solution in a size-optimized design, enabling Zeta to run reliably at up to 85ºC. The heat spreader conducts heat directly to the system chassis for maximum heat dissipation to the ambient environment and minimum radiation into the enclosure interior. By reducing the interior temperature, Zeta helps to improve overall system reliability. In addition the bottom side heat spreader leaves the entire top side of the board free for expansion and simplifies system configuration and maintenance.

 Available Models

Zeta is available with three different processor options. Each CPU may be paired with both the digital I/O and full analog/digital I/O baseboard.

Development Support

Operating system support is available for Linux (Ubuntu 16.04), and Windows 10 IoT. Drivers and instructions are available for free download on the Diamond website. Software development kits / board support packages are available as well and consist of the selected operating system installed and pre-configured on a solid state flashdisk (SSD).

Development Kits

Zeta is available in a complete development kit that includes a full set of I/O cables and the selected SDK. Simply install the pre-configured flashdisk, attach cables / keyboard / mouse / monitor, power up, and the system is ready to run.

Cable kits

The Zeta cable kit includes cables for all I/O features on Zeta except LCD. Details are provided below. Individual cables are available as a special order item; minimum order quantities and leadtimes may apply.

An LCD / backlight cable kit is available for specific displays used in our manufacturing environment. Customers may purchase this cable kit as a starting point and modify the LCD ends to support their specific display.
