Compact Bay Trail SBC has option for third GbE port

Jan 22, 2019 — by Eric Brown — 681 views

Axiomtek’s “CAPA84E” is a 3.5-inch Bay Trail SBC with an optional third GbE port, dual M.2 slots, plus VGA, DisplayPort, USB 3.0, SATA, and -20 to 70°C support.

Axiomtek’s motto may well be: “If first you succeed, iterate until you don’t.” The king of the spinoffs has released yet another iteration of one of the first Intel Bay Trail SBCs, the CAPA841, which in 2015 was followed by the slightly scaled down CAPA840. The new CAPA84R similarly supports Bay Trail and conforms to the 3.5-inch form factor, but with a different mix of features.

Compared to the CAPA840, the CAPA84R removes more than it adds. On the plus side, you get an optional third GbE port. The dual mini-PCIe slots have advanced to a pair of M.2 slots, one of which supports SATA. The HDMI port has switched to a DisplayPort. There’s also a new SMBus interface.

On the deficit side, the new model loses the CAPA840’s Axiomtek ZIO expansion interface, and it has fewer USB ports, with only one USB host port on the coastline and dual internal USB 2.0 interfaces. The earlier wide-range power supply is now locked at 12V, and there’s no more battery support.

    Strange . . . the Bay Trail architecture has been horribly buggy on most Linux kernel’s newer than 4.1.3. I wonder why any company would continue to use it?
