3.5-inch Apollo Lake SBC has dual mini-PCIe slots and triple displays
Nov 21, 2017 — by Eric Brown 3,430 viewsAvalue’s Linux-friendly, 3.5-inch “ECM-APL2” SBC features Apollo Lake SoCs, 2x GbE, 4x USB 3.0, 2x mini-PCIe, triple displays, and optional -40 to 85°C.
Avalue’s 3.5-inch, Apollo Lake based ECM-APL single-board computer was announced a year ago, shortly after Intel unveiled its Apollo Lake generation. Now it has followed up with an ECM-APL2 3.5-incher with a slightly different, and reduced, feature set.

Like the original, the new model supports up to 8GB of 1866MHz DDR3L, and features a wide range 12-26V power input and optional -40 to 85°C operation. It similarly runs Linux or Windows 10 on Atom, Celeron, and Pentium Apollo Lake SoCs. The specific Atom models were not listed, but the earlier ECM-APL supported the quad-core Atom x7-E3950 and Atom x5-E3940, and the dual-core Atom x5-E3930.
Compared to the ECM-APL, the ECM-APL2 eliminates the M.2 and micro-SIM slots in favor of a half-size mini-PCIe slot. As before, there’s a full-size mini-PCIe with mSATA support.

Like the ECM-APL, the new model supports triple displays, and offers 2x HDMI ports. However, instead of the LVDS interface you get a VGA header. Previously there were 5x RS-232 and one RS-232/422/485, but the new model’s serial interfaces are limited to 2x RS-232/422/485, one of which is on the coastline. On the plus side, you get dual USB 2.0 headers instead of one.
