Diamond Systems Zeta is a Miniature SBC Based on Bay Trail/Apollo Lake COM Express Mini Modules

Diamond Systems, a Silicon valley based company providing embedded computing solutions for transportation, energy, aerospace, defense, manufacturing, medical and research market, has recently introduced Zeta single board computer comprised of a baseboard, a choice of COM Express Mini type 10 modules based on Intel Bay Trail or Apollo Lake processor, and a heatspreader for cooling.

The company explains the small size and high feature density of the solution make it particularly suitable for mobile applications. The SBC also supports a wide range 6-36VDC input voltage, and works in -40 to +85°C temperature range.
