Apollo Lake Pico-ITX SBC supplies mini-PCIe and M.2 expansion

Jul 23, 2019 — by Eric Brown 8,980 views

Axiomtek’s “PICO319” SBC is built around a quad-core Atom x5-E3940 SoC and offers 2x GbE, 2x USB 3.0, DP and LVDS, mini-PCIe and M.2, and -40 to 70°C support.

The PICO319 is the latest of several Axiomtek Pico-ITX boards with an Intel Apollo Lake processor, including last year’s PICO316. The PICO319 incorporates the quad-core, up to 1.8GHz Atom x5-E3940 instead of the PICO316’s choice of a Pentium N4200 or Celeron N3350. The Atom x5-E3940 enables the PICO319 to support a wider temperature range of -40 to 70°C. No OS support was listed, but the earlier PICO316 supports Linux (Red Hat, Fedora, Ubuntu) and Windows.

The fanless, 100 x 72mm PICO319 lacks the PICO316’s dedicated SATA III interface, but offers a half-sized mini-PCIe slot with mSATA and wireless support, as well as an optional SIM card module. There’s also an M.2 B-key 2242/3042 interface that was missing from the earlier model that enables SATA, USB 2.0, and PCIe x2.

Instead of an HDMI port, you get a DisplayPort, and once again there’s an LVDS interface for dual simultaneous displays. The line-out audio jack has been replaced with an onboard audio interface with line-in and mic-in, as well as the earlier line-out.

The PICO319 gives you dual USB 3.0 host ports instead of the earlier 3x 3.0 Type-A and Type-C ports. One of the two serial interfaces is now RS-232/422/485, and the board adds a digital I/O header. The PICO319 offers a 12V input with an AT auto power-on instead of the earlier 5V input. Most of the other features remain the same, including dual GbE ports and up to 8GB DDR3L.
