$99 SBC runs Linux on 1GHz dual-core ARM SOC

Apr 3, 2013  |  Rick Lehrbaum

Embest is accepting pre-orders for a $99 single-board computer (SBC) based on a 1GHz dual-core Freescale i.MX6 ARM Cortex-A9 system-on-chip (SOC). The compact “MarS Board” provides interfaces for Gig-Ethernet, high-speed USB, HDMI, camera, and more, and it’s supported with ready-to-use embedded Linux and Android OS images.

The MarS Board’s small size (100 x 65 mm) precludes fitting “real-world” style connectors for all interfaces directly on-board. Consequently, it provides a pair of 24-pin female header connectors topside, into which various adapters can be plugged in order to access all the board’s features (see photo and block diagram down below).

Software and hardware options

Embest will support the MarS Board with ready-to-use embedded Linux 3.0.15 and Android 4.0.4 OS images. Additionally, the company says it can supply a demo version of uC/OS-II V2.92.05 for the SBC.

Hardware add-ons for the MarS Board will include a series of expansion options, including a USB WiFi module, an HDMI-to-VGA converter module, and 4.3- and 7-inch TFT LCD touchscreen displays.

    The first paragraph says it has SATA, but later on it is not listed. I think it is not wired to expansion or onboard connectors, so the board does not have SATA, even if the SOC supports it (I haven’t checked). You may want to check and correct the first paragraph if needed. Thanks.

    In what world is a mini USB port attached to an FT232 an “RS232 port”?

    Hello!

    Do you know if the electronic schematic will be available for everyone?
