Industrial computer runs Linux on quad-core i.MX6

Dec 3, 2013 — by Eric Brown 1,894 views

Via Technologies announced a ruggedized, fanless industrial “AMOS-820” computer based on its VAB-820 Pico-ITX board and Freescale’s i.MX6Quad SoC. The Via AMOS-820 supports Linux, Android, and WEC7, offers a variety of USB, serial, CAN, HDMI, and gigabit Ethernet connectivity, and can withstand -20 to 65°C temperatures.

Designed for a wide range of industrial automation, transportation, HMI, and energy management applications, the Via AMOS-820 is built around Via’s first quad-core Pico-ITX board, the recently unveiled VAB-820.

The board incorporates Freescale’s Cortex-A9 based i.MX6Quad system-on-chip clocked at 1GHz, which integrates a trio of specialized GPUs. The VAB-820 includes coastline HDMI, gigabit Ethernet, composite video, and dual USB 2.0 ports.


The AMOS-820 computer uses the VAB-820’s same complement of 1GB RAM and 4GB flash, and similarly offers a microSD slot, along with a boot switch between microSD and SPI flash sources. The computer offers front I/O including two COM ports, one DIO port, two CAN ports, one USB 2.0 port, and one Micro-USB 2.0 OTG port. The front panel also provides a DC power jack, as well as audio line-in, line-out and mic-in jacks.
