EOMA-200
- Dimensions: 100mm x 65mm PCB in a 103 x 68 x 16mm case
- Pinouts: 4 50-pin B2B connectors providing 200 mandatory pins
- Extensibility: 30mm x 14mm front-facing panel space and 2nd 65mm x 14mm front-facing panel
- Power provision: 5V @ 3.5A and 3.3V @ 3.5A (29 Watts total)
- Target uses: Small Desktop systems, Micro servers, Smart NAS Home Servers, Digital Signage, Industrial PCs, Education and R&D purposes.
Introduction
With many standards providing 200 or more pins, the differentiator which makes EOMA-200 worthwhile is that all other standards are bare PCB factory-only modules with optional sizes and optional functions. These factors combine to make other standards realistically installable only by experts or technical engineers with knowledge of ESD precautions and the full details of the available options.
The EOMA-200 modular standard is designed to be user-installable in mass-volume appliances. There are no options on the pinouts, thus making the purchasing decisions and the installation easy for the average person. Instead, options for extensibility are offered via two front-facing panels, in exactly the same way that standard ITX and ATX motherboards provide a standard front-facing area. One is of size 30mm x 14mm, and the other is of size 65mm x 14mm. The 65mm panel is sufficient to fit up to 4 Ethernet ports, or up to 8 USB2/3 ports, an HDMI connector, eSATA etc. The 30mm panel is intended but not limited to having an on-board MiniPCIe slot behind it, such that WIFI SMA connectors can be put into the 30mm panel.
