Rugged signage player runs Android on quad-core i.MX6

Feb 12, 2015 — by Eric Brown 924 views

AOpen’s rugged “MEP320” media player and signage device runs Android 4.2.2 on a 1GHz Freescale i.MX Quad, and offers a thin profile and dual HDMI ports.

Taiwanese OEM vendor AOpen has long been making Linux-ready mini-PCs such as its circa-2010 Intel Core-based MP57. Now, it’s introducing a rugged AOpen Media Engine MEP320 Android media player for digital signage based on an ARM platform. Its other current signage players run Windows on Intel processors.

The MEP320 runs on a quad-core Freescale i.MX6 with 1GB of DDR3 RAM. You get 8GB of eMMC flash, an SD slot, and four USB ports for storage. A USB OTG port is also available, along with dual HDMI ports, a COM port, and audio I/O.

The system is designed to communicate with the outside world with a gigabit Ethernet port. However, WiFi, Bluetooth, and 3G are optional, and the system is fitted with antenna holes and a SIM slot. It’s likely that these options take up the one available mini-PCIe slot.
