Linux-ready i.MX6 SBC is loaded with wireless options

Apr 30, 2015 — by Eric Brown 1,856 views

Forlinx launched an SBC that runs Linux or Android on a quad-core i.MX6, and offers extras like WiFi, Bluetooth, GPS, 3G, and an image sensor interface.

China-based Forlinx Embedded Technology first appeared on LinuxGizmos last October when it released an OK335xS-II SBC with a TI Sitara AM3354 SoC. Like the OK335xS-II, the new i.MX6-based, sandwich-style SBC embeds a soldered COM, which appears to be available separately. The COM is slightly larger than the previous model, at 60mm square, and the baseboard is a sizable 190 x 130mm.

The i.MX6 module runs Android 4.4 or Linux, including Ubuntu, on a quad-core Cortex-A9 Freescale i.MX6 SoC with 1GB of DDR3 RAM and 8GB eMMC flash. The module provides a gigabit Ethernet controller, and supports I/O including HDMI 1.4, dual-channel LVDS, SATA, CAN, USB, mini-PCIe, and image sensor interfaces.
